Caching in ASP .NET Core:

Introduction:

Effective data caching techniques are critical to improving the performance of web applications in the modern digital environment, where speed and scalability are critical requirements. The robust caching features of Microsoft’s open-source, cross-platform ASP.NET Core framework can greatly increase the scalability and responsiveness of web applications. We’ll examine the advantages, methods for implementation, and best practices of caching in ASP.NET Core in this article.

 The Advantages of Caching in ASP.NET Core:

Caching stores frequently accessed data temporarily, reducing the need to retrieve it from its original source repeatedly. In ASP.NET Core, caching provides several advantages, including:

  • Enhanced Performance: Caching lowers the latency involved in retrieving data from its original source by keeping frequently accessed data in memory, giving users faster response times.
  • Decreased Database Load: By providing cached data rather than querying the database for each request, caching helps reduce the strain on the database server and increase system scalability.
  • Improved Scalability: ASP.NET Core apps are more responsive and scalable when they use caching to manage more concurrent users and requests without sacrificing performance.

Types of Caching in ASP.NET Core:

Different caching mechanisms that meet different needs and scenarios are supported by ASP.NET Core. Several frequently utilized types of caching include:

  • In-Memory Caching: This technique keeps data in the memory of the application so that it is easily accessible to queries made later. For storing small to medium-sized data sets that are accessed frequently, this kind of caching is appropriate.
  • Distributed Caching: With distributed caching, data that has been cached can be shared between several applications or even between various web farm servers. Support for distributed caching with providers like Redis, SQL Server, or NCache is integrated into ASP.NET Core.
  • Response Caching: This technique allows the entire HTTP response to be cached, including the status codes, HTTP headers, and HTML content that is generated. For content that can be cached at the HTTP level and is static or semi-static, this kind of caching is perfect.

Implementing Caching in ASP.NET Core:

Developers can take the following actions to take advantage of caching in ASP.NET Core:

  • Configure Caching Services: Use the AddMemoryCache() or AddDistributedMemoryCache() methods to register caching services for either distributed or in-memory caching in the dependency injection container of the ASP.NET Core application.
  • Install Caching Middleware: To enable response caching, add caching middleware to the application’s request processing pipeline by either implementing custom middleware for more granular control or by using the UseResponseCaching() method.
  • Decorate Cached Resources: To define caching policies, such as cache duration, cache location, and cache profiles, decorate controller actions or Razor pages with caching attributes like [ResponseCache].

 Best Practices for Caching in ASP.NET Core:

The following best practices should be taken into consideration in order to optimize the advantages of caching while avoiding typical pitfalls:

  • Use Caching Wisely: Only store in cache data that is likely to be frequently retrieved or computed at a high cost. Refrain from over-caching or caching frequently changing volatile data.
  • Track Cache Performance: To guarantee optimal cache performance and avoid memory-related problems, track cache hit rates, eviction rates, and memory usage.
  • Use Cache Invalidation: Use cache expiration policies or manual cache invalidation mechanisms, among other cache invalidation techniques, to guarantee that data in the cache is accurate and current.

 Conclusion:

Caching is a potent method for enhancing ASP.NET Core applications’ responsiveness, scalability, and performance. Developers can greatly lower latency, lessen database load, and improve user experience by utilizing caching mechanisms like in-memory caching, distributed caching, and response caching. To optimize its advantages while averting any potential downsides, caching must be used sparingly and in accordance with best practices. Because caching is a fundamental component of optimization strategies, ASP.NET Core applications can easily scale to meet the demands of contemporary online environments while delivering lightning-fast performance.

Dependency Injection in ASP.NET Core

Building Modular and Testable Applications with Dependency Injection in ASP.NET Core

Introduction:

A key component of developing ASP.NET Core applications that encourages modularity, maintainability, and testability is dependency injection, or DI. In this post, we’ll examine the foundations of dependency injection in ASP.NET Core, as well as its advantages and practical uses for developing organized and expandable applications.

Understanding Dependency Injection:

Dependency injection is a design pattern that assists in the management of dependencies among various components in a software system. It refers to the technique of supplying the objects that a class requires (its dependencies) from outside rather than creating them within the class itself in the context of ASP.NET Core. This method makes classes more modular and testable.

Benefits of Dependency Injection in ASP.NET Core:
1. Modular Code: By injecting dependencies into classes, each class can concentrate on its own functionality without being tethered to the implementation details of its dependencies. As a result, the code becomes more modular and maintainable.
2. Testability: Dependency injection makes unit testing easier by allowing developers to replace real implementations of dependencies with mock or test implementations. This facilitates the isolation and testing of individual components.
3. Extensibility: It is easier to extend an application’s functionality with dependency injection by introducing new components or swapping out existing ones. This is especially useful when evolving and scaling an application.
Implementing Dependency Injection in ASP.NET Core:
1. Service Registration:

Services in ASP.NET Core are registered at application startup in the dependency injection container. Services can be added to the container via the ‘ConfigureServices’ method in the ‘Startup’ class.

public void ConfigureServices(IServiceCollection services)

{

    services.AddTransient<IMyService, MyService>();

    // Add more services...

}

‘IMyService’ is the interface in this example, and ‘MyService’ is the matching implementation. ‘Transient’ means that each time a request is made, a new instance of ‘MyService’ is created.

2. Constructor Injection:

Use the constructor of a class to inject dependencies into it. The necessary dependencies are automatically provided by the DI container when a class instance is created.

public class MyController : Controller

{

    private readonly IMyService _myService;

    public MyController(IMyService myService)

    {

        _myService = myService;

    }

    // Controller actions...

}

3. Using Dependency Injection in Middleware:

Dependency injection can also help middleware components in the ASP.NET Core request processing pipeline. The ‘Invoke’ method can have services injected into it.

public class MyMiddleware

{

    private readonly RequestDelegate _next;

    private readonly IMyService _myService;

    public MyMiddleware(RequestDelegate next, IMyService myService)

    {

        _next = next;

        _myService = myService;

    }

    public async Task Invoke(HttpContext context)

    {

        // Use _myService...

await _next(context);

    }

}

Scopes and Lifetimes of Services:

Several service lifetimes, such as ‘Transient’, ‘Scoped’, and ‘Singleton’, are supported by ASP.NET Core. Managing the lifespan of service instances requires an understanding of these lifetimes.

1. Transient: Whenever an instance is requested, a new one is created.
2. Scoped: Each request generates a single instance. Within the parameters of an HTTP request, it is shared.
3. Singleton: For the duration of the application, only one instance is created.
Best Practices for Dependency Injection in ASP.NET Core:

1. Choose Constructor Injection: For improved readability and maintainability, inject dependencies via the constructor.

2. Employ Interfaces: Write code that checks against interfaces as opposed to specific implementations. This encourages testability and flexibility.

3. Avoid the Service Location Anti-Pattern: Avoid the ‘ServiceLocator’ pattern, which involves retrieving services directly from the container within a class.

4. Register Services as Interfaces: When registering services, use interfaces rather than concrete implementations.

services.AddTransient<IMyService, MyService>();

  Conclusion:

Dependency injection is a powerful design pattern that improves the design, testability, and maintainability of ASP.NET Core applications significantly. Developers can create modular, extensible, and testable applications by leveraging the built-in dependency injection container. Understanding dependency injection principles is critical for developing robust and scalable ASP.NET Core applications.

Web API with ASP.NET Core using MVC

Creating a web API with ASP.NET Core using the MVC (Model-View-Controller) pattern entails creating controllers to handle HTTP requests, models to represent data, and routes for the API. A step-by-step guide to creating an MVC web API with ASP.NET Core is provided below.

Step 1 Install the Necessary Software

Check that your machine has the.NET SDK installed.

Step 2 Create a New ASP.NET Core MVC Web API Project

Run the following commands in a terminal or command prompt

dotnet new mvc -n MyMvcWebApi

cd MyMvcWebApi

This will create a new ASP.NET Core MVC project called MyMvcWebApi and navigate to its directory.

Step 3 Explore the Project Structure

Launch your preferred IDE and open the project. Controllers, Models, and Views are among the folders in the project structure.

Controllers In this section, you will define your API controllers.

Models To represent your data, you can create model classes.

Views Although views are not required for an API, this folder is included in the standard MVC structure.

Step 4 Create a Model

To represent your data, create a model class. Create a file called Item.cs in the Models folder, for example

public class Item

{

    public int Id { get; set; }

    public string Name { get; set; }

}

Step 5 Establish a Controller

Add a new file to the Controllers folder, such as ItemsController.cs, to create a controller

using Microsoft.AspNetCore.Mvc;

using System.Collections.Generic;

namespace MyMvcWebApi.Controllers

{

    [Route(api[controller])]

    [ApiController]

    public class ItemsController  ControllerBase

    {

        private static ListItem _items = new ListItem

   {

            new Item { Id = 1, Name = Item 1 },

            new Item { Id = 2, Name = Item 2 },

            new Item { Id = 3, Name = Item 3 }

        };

GET apiitems

        [HttpGet]

        public ActionResultIEnumerableItem Get()

        {

            return _items;

        }

GET apiitems1

        [HttpGet({id})]

        public ActionResultItem Get(int id)

        {

            var item = _items.Find(i = i.Id == id);

            if (item == null)

                return NotFound();

   return item;

        }

         POST apiitems

        [HttpPost]

        public ActionResultItem Post([FromBody] Item newItem)

        {

   newItem.Id = _items.Count + 1;

            _items.Add(newItem);

            return CreatedAtAction(nameof(Get), new { id = newItem.Id }, newItem);

        }

         PUT apiitems1

        [HttpPut({id})]

public IActionResult Put(int id, [FromBody] Item updatedItem)

        {

            var existingItem = _items.Find(i = i.Id == id);

            if (existingItem == null)

                return NotFound();

existingItem.Name = updatedItem.Name;

            return NoContent();

        }

         DELETE apiitems1

        [HttpDelete({id})]

        public IActionResult Delete(int id)

{

            var itemToRemove = _items.Find(i = i.Id == id);

            if (itemToRemove == null)

                return NotFound();

            _items.Remove(itemToRemove);

            return NoContent();

         }

     }

}

Step 6 Run the Program

Enter the following command at the command prompt or terminal

dotnet run

The URL for your API will be http://localhost:5000 or https://localhost:5001. Open an API testing tool such as Postman:

GET Request: To retrieve items, open https://localhost:5001/api/items.
POST Request: To add a new item, submit a POST request with a JSON body to https://localhost:5001/api/items.
PUT Request: To update an item, submit a PUT request with a JSON body to https://localhost:5001/api/items/1.
DELETE Request: To delete an item, send a DELETE request to https://localhost:5001/api/items/1.

Step 7 Explore and Extend

To improve your web API, investigate additional ASP.NET Core MVC features like middleware, authentication, dependency injection, and model binding. Depending on the needs of your application, you can handle various HTTP methods, define more models, and add more controllers.

Developing ASP.NET Core MVC Web Applications:

Introduction:

Creating dynamic and interactive web pages using the ASP.NET Core framework is required when developing ASP.NET Core MVC (Model-View-Controller) web applications. Model, View, and Controller (MVC) is a design pattern that divides an application into three main components: Model, View, and Controller. ASP.NET Core MVC is a lightweight, cross-platform, open-source framework for building modern, scalable web applications.

Here is a step-by-step tutorial for creating ASP.NET Core MVC web applications:

1. Install Prerequisites:

As your development environment, install Visual Studio or use Visual Studio Code.

Install the.NET SDK from the Microsoft website:

https://dotnet.microsoft.com/download

2. Create a new ASP.NET Core MVC project as follows:

Open Visual Studio and choose “Create a new project.”

Select “ASP.NET Core Web App” and then “ASP.NET Core with MVC” as the template.

Configure the project parameters and then click “Create.”

3. Understand the Project Structure:

Look into the project structure to learn about the key components:

Controllers: Controllers are responsible for handling user input and orchestrating interactions between the model and the view.

Views: Present information to the user and collect user input.

Models: Represent the application’s data and business logic.

4. Define Models:

Model classes should be created to represent the data entities in your application.

Data annotations can be used to validate data and define metadata.

public class Product

{

    public int Id { get; set; }

    [Required]

    public string Name { get; set; }

    public decimal Price { get; set; }

}

5. Create Controllers:

To handle user requests and interact with models, create controllers.

Define controller actions to respond to specific HTTP requests.

public class ProductController : Controller

{

    public IActionResult Index()

    {

        // Retrieve and return a list of products

        return View(products);

    }

public IActionResult Details(int id)

    {

        // Retrieve a specific product by id and return it

        return View(product);

    }

}

6. Develop Views:

To define the presentation layer, create view files (.cshtml).

To display dynamic content, use Razor syntax to embed C# code within HTML.

@model List<Product>

<h2>Product List</h2>

<ul>

    @foreach (var product in Model)

    {

        <li>@product.Name - $@product.Price</li>

    }

</ul>

7. Configure Routing:

Define routes in the Startup.cs file to map URLs to controller actions.

app.UseEndpoints(endpoints =>

{

    endpoints.MapControllerRoute(

        name: "default",

        pattern: "{controller=Home}/{action=Index}/{id?}");

});

8. Handle Form Submissions:

In controllers, use the HttpPost attribute to handle form submissions.

[HttpPost]

public IActionResult Create(Product product)

{

    // Validate and save the new product

    return RedirectToAction("Index");

}

9. Implement Data Access:

To interact with databases, use Entity Framework Core or other data access technologies.

10. If desired, include authorization and authentication:

Authenticate and authorize users in accordance with the specifications of your application.

11. Test Your Application:

Run your application locally and verify various scenarios to test it.

12. Publish Your Application:

Publish your ASP.NET Core MVC application to a cloud platform or hosting environment.

Note: Always refer to the official ASP.NET Core documentation for more information on each stage of development: https://docs.microsoft.com/en-us/aspnet/core/

 

Microservices Architecture with DOTNET Core

Introduction:
The ability of microservices architecture to break down large, monolithic applications into smaller, independent services has led to widespread adoption. This article delves into the design principles and implementation strategies for developing microservices with DOTNET Core, Microsoft’s versatile and powerful framework.

Understanding Microservices Architecture:

Microservices is a design style in which an application is made up of loosely coupled, independently deployable services. Each service is intended to carry out a specific business function and communicates with other services via well-defined APIs.

Design Principles:
1. Single Responsibility Principle (SRP): Each microservice should be responsible for a single business capability. This ensures ease of use and maintainability.
2. Decentralized Data Management: Databases belong to microservices. Because of this decentralization, dependencies are reduced and each service is free to select the database technology that best meets its needs.
3. Inter-Service Communication: APIs are used by services to communicate with one another, and they frequently use lightweight protocols such as HTTP/REST or messaging queues. This allows for independence and flexibility in technology stack selection.
4. Fault Tolerance and Resilience: Create services that are resistant to failure. To handle faults gracefully, use mechanisms such as circuit breakers and retries.
5. Continuous Integration and Deployment (CI/CD): Use CI/CD techniques to automate the processes of building, testing, and deployment. This guarantees the delivery of microservices quickly and consistently.
6. Scalability: Microservices can be scaled independently based on demand. By horizontally scaling instances, you can design services to handle varying levels of load.

Implementation with DOTNET Core:
1. Service Development: For each microservice, create a separate DOTNET Core project. Build web APIs with ASP DOTNET Core and consider high-performance communication technologies like gRPC.
2. API Gateway: Set up an API Gateway to manage and route requests to the proper microservices. In Azure, tools such as Ocelot and API Gateway can be used.
3. Service Discovery: To dynamically locate and call services, use service discovery tools such as Consul or Eureka. This is critical for dealing with the fluid nature of microservices.
4. Containerization: Use Docker to containerize each microservice. This ensures consistency across environments and makes deployment easier.
5. Orchestration with Kubernetes: Use Kubernetes to orchestrate and manage containers. Kubernetes makes it easier to deploy, scale, and manage microservices.
6. Logging and Monitoring: Consolidate logging and monitoring. Tools such as the ELK stack (Elasticsearch, Logstash, Kibana) or Application Insights can provide insights into the behavior of microservices.
7. Security: Implement an all-encompassing security strategy. Utilize OAuth for authentication, JWT for token-based authorization, and HTTPS for secure communication.
8. Testing: For each microservice, perform unit testing, integration testing, and end-to-end testing. In this context, tools like xUnit, NUnit, and Postman can be useful.
9. Database Management: Select databases based on the needs of the microservices. Accept polyglot persistence and think about SQL and NoSQL databases.
10. Event-Driven Architecture: Think about using event-driven patterns with message brokers such as RabbitMQ or Apache Kafka. Asynchronous communication between microservices is enabled by events.

Conclusion:
Using DOTNET Core to build microservices necessitates adhering to architectural principles that prioritize independence, scalability, and maintainability. Developers can create a robust microservices ecosystem that meets the demands of modern, scalable applications by using a containerized and orchestrated approach. The combination of DOTNET Core and microservices unleashes the power of agile development, rapid deployment, and efficient scaling, enabling organizations to deliver resilient and scalable applications in today’s dynamic computing landscape.

4. Entity Framework Core: An open-source, lightweight, and extensible object-relational mapping (ORM) framework is called Entity Framework Core. It makes working with databases using C# objects easier for developers by streamlining persistence and data access.

 

Getting Started:

Setting up your development environment, starting a new project, and learning the core principles of ASP DOTNET Core are the first steps in getting started with the framework. Here is a step-by-step tutorial to get you started with ASP DOTNET Core web application development.

 

Step 1: Install Prerequisites

Make sure the following is installed on your computer before you begin:

a.) DOTNET SDK: The DOTNET SDK can be downloaded and installed from the official DOTNET website: Get the DOTNET SDK here.

b.) Code Editor: Select a code editor for your project. Although Visual Studio Code is a well-liked option, you are free to use any other code editor of your choosing.

 

Step 2: Create a New Project for ASP DOTNET Core

To start a new ASP DOTNET Core project, launch a terminal or command prompt and type the following commands:

# Create a new folder for your project

mkdir MyFirstAspNetCoreApp

cd MyFirstAspNetCoreApp

# Create a new ASP DOTNET Core web application

dotnet new web -n MyFirstAspNetCoreApp

 

Step 3: Explore the Project Structure

Go to the project folder and examine the project hierarchy. Important documents and directories consist of:

Program.cs: Program.cs is the application’s entry point.

Startup.cs: Startup.cs is responsible for configuring the application’s services and middleware.

wwwroot: Static files (CSS, JavaScript, images) are stored in the wwwroot directory.

Controllers: The controllers that handle requests are listed here.

Views: This collection contains the views that define the user interface.

Models: Contains the data models that the application employs.

 

Step 4: Run the Program

View in SQL

View in SQL

A view in SQL is a virtual table created from the results of a SELECT query. Views simplify complex queries, encapsulate logic, and provide an abstraction layer over the underlying tables. They can be used to present data in a more meaningful or secure manner than querying the underlying tables directly. Here’s a quick rundown of how to create and use views in SQL:

Creating a View:

The CREATE VIEW statement is used to create a view. The fundamental syntax is as follows:

CREATE VIEW view_name AS

SELECT column_name_1, column_name_2, …

FROM table_name

WHERE condition;

For example, let us create a new table called studentdata using the syntax shown below.

create table studentdata(

sno int,

sname varchar(100),

slocaction varchar(100),

smothertongue varchar(100));

Insert some records as well using the syntax shown below.

insert into studentdata values(1, ‘RAM’, ‘CHENNAI’, ‘TAMIL’)

insert into studentdata values(2, ‘RAJ’, ‘CHENNAI’, ‘HINDI’)

insert into studentdata values(3, ‘RAVI’, ‘HYDERABAD’, ‘TELUGU’)

insert into studentdata values(4, ‘RAJESH’, ‘HYDERABAD’, ‘TAMIL’)

insert into studentdata values(5, ‘RAJIV’, ‘CHENNAI’, ‘TELUGU’)

Select query syntax can be used to display the table records.

SELECT * FROM studentdata

Create a view using the syntax shown below.

CREATE VIEW TN AS

SELECT * FROM studentdata

WHERE slocaction = ‘CHENNAI’

Using a View:

After you’ve created a view, you can query it like a regular table with the following syntax:

SELECT * FROM view_name

With reference to the given example,

SELECT * FROM TN

Updating a View:

You can use the ALTER VIEW statement to update views:

ALTER VIEW view_name AS

SELECT column_name_1, column_name_2, …

FROM table_name

WHERE condition;

In Microsoft SQL Server, you can use the CREATE OR ALTER VIEW statement to replace an existing view or create a new one. This is similar to the CREATE OR REPLACE VIEW syntax found in other database systems. Using the preceding example:

ALTER VIEW TN AS

SELECT * FROM studentdata

WHERE smothertongue = ‘TAMIL’

Dropping a View:                

The DROP VIEW statement is used to remove a view:

DROP VIEW employee_view;

Thinking back to the earlier illustration:

DROP VIEW TN

 

Multiple Views:

Views enable you to create a virtual table in a relational database based on the results of a SELECT query. You can use JOIN operations in your SELECT statement to combine data from multiple tables in a view. Here’s a general guide to creating a view with multiple tables:

Consider the following scenario: you have two tables: customers and orders. The customers table contains information about customers, and the orders table contains information about the orders that these customers have placed.

— Sample customers table

CREATE TABLE customers (

    CustomerId INT PRIMARY KEY,

    CustomerName VARCHAR(50),

    Email VARCHAR(50)

);

— Sample orders table

CREATE TABLE orders (

    OrderId INT PRIMARY KEY,

    CustomerId INT,

    OrderDate DATE,

    TotalAmount DECIMAL(10, 2),

    FOREIGN KEY (CustomerId) REFERENCES customers(CustomerId)

);

Let us also insert some sample records into both tables using the insert query:

INSERT INTO customers VALUES (1, ‘RAM’, ‘ram@mail.com’)

INSERT INTO customers VALUES (2, ‘RAJ’, ‘raj@mail.com’)

INSERT INTO customers VALUES (3, ‘RAVI’, ‘ravi@mail.com’)

INSERT INTO orders VALUES (101, 1, ‘2023/11/02’, 10000)

INSERT INTO orders VALUES (102, 2, ‘2023/11/03’, 12000)

Check it out with the following select query:

SELECT * FROM customers

SELECT * FROM orders

Let’s now create a view that combines data from both tables:

CREATE VIEW CustomerOrderView AS

SELECT

    c.CustomerId,

    c.CustomerName,

    c.Email,

    o.OrderId,

    o.OrderDate,

    o.TotalAmount

FROM

    customers c

JOIN

    orders o ON c.CustomerId = o.CustomerId;

The CustomerOrderView view is created in this example by selecting specific columns from both the customers and orders tables. The JOIN clause is used to join rows from both tables using the CustomerId column in common.

After you’ve created the view, you can query it like any other table:

SELECT * FROM CustomerOrderView

Remember that the exact syntax can change based on the database management system (SQL, PostgreSQL, MySQL, etc.) you are using. Depending on the system you are working with, modify the SQL statements as necessary.

SQL and .NET (sometimes spelled DOTNET) are two separate technologies that are commonly utilized in software development. SQL, which stands for Structured Query Language, is a powerful computer language that was created primarily for maintaining and manipulating relational databases. It provides a standardized approach for developers to accomplish operations including accessing data, entering records, updating information, and designing database structures.

.NET, on the other hand, is a framework developed by Microsoft for building various types of applications, including desktop, web, and mobile applications. It provides a comprehensive set of libraries and tools for developers to build, deploy, and run applications. .NET supports multiple programming languages, including C#, F#, and Visual Basic, and it includes a runtime, a set of libraries, and development tools.

While SQL is primarily focused on working with databases and managing data, .NET is a broader framework that covers a wide range of application development aspects. However, it’s common for developers to use SQL in conjunction with .NET when building applications that require interaction with a database.

In a typical scenario, a .NET application may use SQL to store and retrieve data from a relational database. This interaction is often facilitated by using an Object-Relational Mapping (ORM) framework, such as Entity Framework, which is a popular component of the .NET ecosystem. Entity Framework allows developers to work with databases using object-oriented principles, making it easier to integrate database operations into .NET applications.

Do you want to know if.NET is still in demand?

There is no need to look any further! .NET is an open-source web framework that is one of the most popular web application development frameworks for creating dynamic websites. With such promising future growth potential, it’s no surprise that professionals with prior experience in this industry are in high demand today. Keep your.NET skills sharp to stay ahead of the curve!

.NET is a framework that provides programming principles for creating a wide range of applications, from web-based to mobile-based. It supports a variety of programming languages, including C#, VB.NET, C++, F#, and others. So, when working with.NET, code is essential. Continue to experiment and study to become a skilled.NET developer!

.NET is the primary framework for developing Windows-based applications. This is due to the fact that.NET is a local framework bundled with Windows that makes it easier for programmers to construct applications. Furthermore, many programmers find it easier to construct web applications in.NET than in Java.

The.NET Framework’s ability to create a highly secure environment for applications is well known. It includes a variety of security mechanisms to ensure maximum protection. One of these mechanisms is the built-in Windows authentication system, which enables developers to create secure and safe applications with ease. This authentication system ensures that only authorized users have access to the application, improving its overall security.

Furthermore, the.NET Framework includes a set of cryptography classes that are essential for protecting sensitive data. These classes enable encryption and decryption, which improves data security. Developers can use these cryptography classes to implement strong encryption algorithms that effectively protect data during transmission and storage. This ensures that confidential data remains private and out of reach of unauthorized individuals.

As a result, by incorporating a wide range of security features, the.NET Framework enables developers to prioritize data protection and mitigate potential security risks when developing applications.

Validation in ASP.NET MVC

Validation is an essential component of any web application, including those created with ASP.NET MVC. It guarantees that data given by users is correct, secure, and satisfies the relevant standards. ASP.NET MVC includes numerous means for performing validation, and I’ll go over some of the major principles and strategies for creating validation in ASP.NET MVC.

 

1.  Model Validation: A basic method for validating data entered into a form is model validation. It entails adding characteristics that specify validation criteria to your model classes through annotation. The most prevalent qualities consist of:

[Required]: Indicates the necessity of a certain attribute.

[StringLength]: Indicates a string property’s minimum and maximum length.

[Range]: Indicates a possible range of values for a numerical attribute.

[RegularExpression]: Uses a regular expression pattern to validate a property.

[Compare]: Compare to ensure two properties of a model has same value.

[DataType(DataType.Password)] : converts the text mode to password mode.

Here’s an example of how to apply the following attributes:

public class Student

{

[Required]

public string FirstName { get; set; }

[StringLength(50, MinimumLength = 3)]

public string LastName { get; set; }

[Range(18, 100)]

public int Age { get; set; }

[RegularExpression(@”^[a-zA-Z0-9]*$”, ErrorMessage = “Invalid characters”)]

public string Username { get; set; }

[Required]

[DataType(DataType.Password)]

public string Password { get; set; }

[Compare(“Password”)]

public string ConfirmPassword { get; set; }

}

 

2. Client-Side Validation: Based on the validation characteristics added to your model properties, ASP.NET MVC can produce client-side validation code. This gives users immediate feedback in their web browsers before they submit the form. You must add the essential JavaScript libraries, such as jQuery Validation, in your project to enable client-side validation.

 

3. ModelState: ASP.NET MVC automatically populates the ModelState object with validation errors after a form is submitted. If there are any validation failures, you can check ModelState.IsValid and display error warnings to the user.

Here’s an example of how to apply the following attribute:

[HttpPost]

public ActionResult Create (Student model)

{

    if (ModelState.IsValid)

    {

        // Process the data and save it.

        return RedirectToAction(“Success”);

    }

    return View(model);

}

 

4. Displaying Validation Errors: The @Html.ValidationMessageFor and @Html.ValidationSummary helper methods can be used to display validation errors in your views. These show error warnings for either the entire model or just a subset of its properties.

Here’s an example of how to apply the following attribute:

@Html.ValidationSummary()

@Html.LabelFor(model => model.FirstName)

@Html.EditorFor(model => model.FirstName)

@Html.ValidationMessageFor(model => model.FirstName)

 

5. Custom Validation: By implementing the IValidatableObject interface or by deriving from ValidationAttribute and defining custom validation attributes, you can establish custom validation rules. You can use this to provide unique validation logic for your models.

 

6. Remote Validation: Remote validation allows you to execute server-side validation checks without requiring a complete page postback. To accomplish this, use the [Remote] attribute in conjunction with a controller action.

 

7. Anti-Forgery Token (CSRF Protection): Anti-forgery tokens must be included in your forms to guard against Cross-Site Request Forgery (CSRF) attacks. In your forms, you can utilize the @Html.AntiForgeryToken() helper method and validate it on the server with the [ValidateAntiForgeryToken] property.

 

These are the main ASP.NET MVC validation features. By employing these methods, you may guarantee that user-submitted data is secure and legitimate, assisting in preserving the application’s integrity.

Data Access in ASP.NET MVC

Data access in ASP.NET MVC refers to the process of retrieving, updating, and modifying data from a database or other data sources for use in a web application. There are various ways to accomplish data access in ASP.NET MVC, and the technology you choose generally relies on the requirements and design of your application. Here are some popular data access methods in ASP.NET MVC:

1. Entity Framework (EF): Microsoft’s Entity Framework is a prominent Object-Relational Mapping (ORM) framework. It enables you to work with your data by abstracting the underlying database using highly typed.NET objects. Entity Framework requires you to define your data model as C# classes, and Entity Framework will construct the SQL queries needed to interface with the database.

Follow these steps to get started with Entity Framework in ASP.NET MVC:

a. Use NuGet to install Entity Framework.

b. Create a DbContext-derived data context class.

Create entity classes to represent database tables.

Interact with your data using LINQ queries.

2. ADO.NET: ADO.NET is a lower-level data access technology that allows you to work directly with databases using data providers. ADO.NET can be used to make database connections, run SQL queries, and retrieve data. While it gives you greater power, it often requires you to write more code than Entity Framework.

You can utilize ADO.NET in ASP.NET MVC by following these general steps:

a. Use SqlConnection to create a database connection.

b. Using SqlCommand, create and run SQL queries or stored procedures.

c. To get data, use SqlDataReader or any data reader.

3. Dapper: Dapper is an ADO.NET-based lightweight Object-Relational Mapping (ORM) library. By offering a quick and simple method to map database records to C# objects without the complexities of Entity Framework, it streamlines data access.

You may use Dapper in ASP.NET MVC by following these steps:

a. Use NuGet to install Dapper.

b. Create SQL queries, then execute them using Dapper’s extension methods and map the results to objects.

 4. Web API and HTTP Services: In some cases, you might be able to receive data from remote servers using web APIs or HTTP services rather than directly accessing a database. To send HTTP queries to external APIs and use the results in your MVC application, you can use libraries like as HttpClient.

You can use HTTP services and web APIs in the following ways:

a. Create controller actions that send HTTP queries.

b. Create C# objects by deserializing the XML or JSON answers.

Selecting the best approach for data access security, error management, and performance optimization is crucial, regardless of the data access method you use. A clean and maintainable architecture should also be achieved by keeping your data access code distinct from your controllers and views. For example, you can encapsulate data access functionality in repositories or services.

Routing in ASP.NET MVC

Routing is a basic element in ASP.NET MVC that governs how URLs are mapped to controller actions in your application. It specifies how incoming requests are handled, as well as which controller and action methods are used to generate the answer. Routing is required when creating clean, user-friendly URLs for your web application.

The following are the main elements and ideas around routing in ASP.NET MVC:

Route Table: The routing configuration in ASP.NET MVC is normally set up in the ‘RouteConfig’ class in your project’s ‘App_Start’ folder. A set of route definitions is stored in the ‘RouteConfig’ class. The ‘MapRoute’ method is used to add these route definitions to the ‘RouteTable.Routes’ collection.

Route Definitions: A route specification contains the URL pattern, the default settings, as well as the controller and action to be executed when a specific URL is matched. An example of a route definition is as follows:

routes.MapRoute(

    name: “Default”,

    url: “{controller}/{action}/{id}”,

    defaults: new { controller = “Home”, action = “Index”, id = UrlParameter.Optional }

);

In this case, the route matches URLs like /Home/Index and delivers them to the controller and action methods defined.

Route Parameters: You can include placeholders like {controller}, {action}, and {id} in the URL pattern encased in curly brackets in the route definition. The arguments indicated by these placeholders are those that will be taken from the URL and provided to the relevant action method. As demonstrated in the last example, the route parameters may also have default values.

Route Constraints: To limit the values that can be entered for route parameters, you can apply restrictions. To guarantee that only numerical values match the route, you can, for example, stipulate that the id parameter must be an integer.

Route Handling: The routing system looks at the URL in an HTTP request and attempts to match it with one of the route definitions in the route table. In the event that a match is discovered, the relevant controller and action are called using the URL’s extracted arguments.

Attribute Routing: ASP.NET MVC allows attribute routing in addition to convention-based routing (as demonstrated in the RouteConfig example). With attribute routing, you may use attributes to define routing information directly on your controller activities. This gives individual actions greater routing flexibility and control.

As an example of attribute routing, consider the following:

[Route(“products/details/{id}”)]

public ActionResult Details(int id)

{

    // Action logic here

}

You can have detailed control over the URL structure for every action method with attribute routing.

In summary, routing is an essential component of ASP.NET MVC because it makes it possible to construct RESTful web applications, organize controllers and actions more effectively, and produce neat, SEO-friendly URLs. When routing is set up correctly, requests are routed to the right controller actions, which provide the user the right response.

Controllers in ASP.NET MVC

Controllers in ASP.NET MVC (Model-View-Controller) are critical in accepting incoming HTTP requests, processing them, and sending appropriate responses to the client. Controllers are in charge of regulating the application’s flow, communicating with models and views, and handling user input. Here are some important points to remember regarding controllers in ASP.NET MVC:

Controllers’ Role: Clients, usually web browsers, send requests over HTTP to controllers. They use the request URL and HTTP verb (GET, POST, etc.) to identify the action method to do. The logic for handling user input, making choices, and coordinating with models and views to produce a response is included in controllers.

Controller Naming Convention: In ASP.NET MVC, controllers usually have names that conclude in “Controller.” HomeController, DefaultController, and UserController are a few examples.

Action Methods: Action methods, which are public methods that respond to certain HTTP requests, make up controllers. The HTTP verbs that action methods respond to are indicated by characteristics like [HttpGet] or [HttpPost]. In order to render the answer, they must process user input, interact with models (data access), and choose the right view.

Routing: Routing is used by the ASP.NET MVC framework to map incoming URLs to controllers and associated action methods. The RouteConfig.cs file is frequently used to define the default route settings.

Parameters and Model Binding: Parameters from the URL, form data, query string, or other sources can be passed to action methods. Model binding is used by ASP.NET MVC to automatically connect incoming data to method parameters.

ActionResult: Action methods will either return an ActionResult or a derived class such as ViewResult, RedirectResult, or JsonResult. The type of answer given to the client is determined by the result type.

Dependency Injection: It is common practice to inject services and dependencies into controllers to make them more tested and manageable.

Filters:

To provide behavior and manage the execution flow of action methods, controllers can be decorated with filters such as permission filters or action filters.

Testing: Unit testing is a useful tool for verifying that controllers operate as intended. Mocking frameworks are frequently used to test controller activities and simulate HTTP requests.

RESTful Controllers: RESTful APIs can be developed with ASP.NET MVC, in which controllers manage the HTTP verbs GET, POST, PUT, and DELETE to carry out CRUD actions on resources.

In summary, controllers are an essential component of the ASP.NET MVC architecture and are in charge of managing the flow control and main logic of the application.

Here’s a simple ASP.NET MVC controller example:

_____________________________________________________________

public class HomeController : Controller

{

public ActionResult Index()

{

// Logic to retrieve and display a list

return View();

}

[HttpGet]

public ActionResult Create()

{

// Logic to create a new data in a form

return View();

}

[HttpPost]

public ActionResult Create(HomeViewModel model)

{

// Process form submission and create a new data

// Redirect to the list or show validation errors

}

}

MVC framework in ASP.NET

Introduction to MVC (Model-View-Controller) in ASP.NET:

MVC (Model-View-Controller) is a common architectural paradigm for constructing online applications in ASP.NET. It provides a structured and organized approach to web application development by dividing the application into three interconnected components: the Model, the View, and the Controller. This separation of concerns makes the codebase easier to manage and maintain, promotes code reusability, and improves overall application adaptability.

Let’s take a closer look at each component:

Model: The Model represents the data and business logic of the application. It contains the data on which your application runs as well as the rules that govern that data. It is in charge of retrieving and storing data from a database or other data sources, as well as carrying out data-related tasks.

View: The View is in charge of rendering the user interface and displaying data to the user. Views in an ASP.NET MVC application are normally built in HTML, but they can also contain embedded code (Razor syntax) to show dynamic content. Views are retained as independent files, making the display layer easier to handle.

Controller: The Controller functions as a go-between for the Model and the View. It processes user requests, interacts with the Model to retrieve or change data, and then selects the appropriate View to show the response to the user. It contains the application’s logic for handling HTTP requests and is the starting point for the majority of user interactions.

Main advantages and characteristics of ASP.NET MVC use:

Separation of Concerns: MVC requires a distinct division of responsibilities, which facilitates application understanding, maintenance, and expansion. Developers are able to work independently on various components because to this separation.

Reusability: MVC improves code reusability and reduces redundancy by allowing models, views, and controllers to be often reused in other application components.

Testability: MVC allows for independent unit testing of each component, which improves code quality and facilitates more effective debugging.

Flexibility: MVC enables developers to add to and modify some areas of the program without compromising the functionality of the other sections. It is now simpler to adjust to evolving needs as a result.

Support for Multiple View Engines: ASP.NET MVC offers flexibility in how you render your views by supporting a number of view engines, such as Razor and Web Forms.

 

Usually, you use one of the MVC project templates to create a project in Visual Studio to begin working with MVC in ASP.NET. Models, views, and controllers are all built up in the fundamental framework of your application by using these templates. After that, you may construct on top of this base by defining your views for data display, writing controller actions for user requests, and defining your data models.

In conclusion, MVC is an effective architectural pattern that encourages the creation of web applications in ASP.NET using an organized methodology. Because of its many benefits for code organization, maintainability, and testability, it is a well-liked option among developers creating ASP.NET web applications.

The Significance of Data Backup

In the era of information, data stands as the backbone of virtually every software application. Whether it’s a user’s preferences in a mobile app or financial records in an enterprise system, data forms the core of functionalities. However, with great power comes the responsibility of safeguarding this data against various threats such as hardware failures, cyberattacks, and human errors. This is where data backup steps in as a savior.

  1. Data Integrity and Recovery

Data loss can be catastrophic, potentially resulting in financial losses, legal ramifications, and loss of trust among users. Backup solutions ensure data integrity by creating copies of essential information at regular intervals. In case of data corruption or loss, these backups act as recovery points, enabling developers to restore the application to a previous state.

  1. Disaster Recovery

Natural disasters, hardware failures, or even simple human errors can disrupt the availability of applications. Data backup plays a pivotal role in disaster recovery, allowing organizations to rebuild their applications and services with minimal downtime.

  1. Security Measures

In the digital age, cybersecurity is of extreme importance. Regular backups can mitigate the damage caused by ransomware attacks or other malicious activities. If a system is compromised, having a backup ensures that attackers can’t hold the data hostage.

  1. Testing and Development

Backed-up data can be a valuable resource for testing and development purposes. Developers can use copies of real data to create realistic testing scenarios or build new features without risking the integrity of the production environment.

Routing in ASP.NET

Routing in ASP.NET is the process of sending HTTP requests to the appropriate controller. Whether a request should be forwarded to the controller for processing or not is up to the MVC middleware. This choice is made by the middleware based on the URL and some configuration data.

In other words, routing in ASP.NET is a mechanism that allows you to define URL patterns and map them to specific resources or handlers in your web application. It enables you to create clean, user-friendly URLs that are more meaningful and descriptive than traditional query-string based URLs.

Routing is an essential part of the ASP.NET MVC (Model-View-Controller) framework and the newer ASP.NET Core framework, although the concept remains similar across both technologies.

Routing’s main goal is to separate your web application’s physical file structure from its URL structure. In the past, URLs in web applications were linked to particular physical server files (for example, a particular.aspx page). However, routing gives you more flexibility when defining the URLs for your web application since it allows you to specify URL patterns and link them to controllers and actions (in MVC) or endpoints (in ASP.NET Core).

To address various scenarios and requirements, ASP.NET MVC supports a number of different forms of routing. The primary routing types that ASP.NET MVC supports are listed below:

Conventional Routing: In ASP.NET MVC, conventional routing is the default routing method. The mapping of URL segments to names of controller and action method uses a pattern-based technique. A URL pattern typically looks like this: “controller/action/id,” where “controller” and “action” stand in for the names of the controller and action method, respectively. It is possible to omit the “id” parameter.

Here’s a basic example of routing in ASP.NET MVC:

// In the RouteConfig.cs file (MVC)
public static void RegisterRoutes(RouteCollection routes)
{
    routes.IgnoreRoute(“{resource}.axd/{*pathInfo}”);
    routes.MapRoute(
        name: “Default”,
        url: “{controller}/{action}/{id}”,
        defaults: new {controller = “Home”, action = “Index”, id = UrlParameter.Optional }
    );
}

In this example, a default route is defined with a pattern like “{controller}/{action}/{id}”. When a user visits a URL like “example.com/Home/Index”, the routing system will map it to the “Index” action method in the “HomeController” within the MVC application. The “id” parameter is optional and can be omitted in the URL.

ASP.NET Core uses a similar concept of routing, but the syntax and configuration are slightly different. Here’s a basic example of routing in ASP.NET Core:

// In the Startup.cs file (ASP.NET Core)
public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
    // Other middleware configurations…
    app.UseRouting();
    app.UseEndpoints(endpoints =>
    {
        endpoints.MapControllerRoute(
            name: “default”,
            pattern: “{controller=Home}/{action=Index}/{id?}”
        );
    });
}

In this example, the UseRouting() method is called to enable routing, and then MapControllerRoute() is used to define the default route pattern.

Routing plays a crucial role in creating clean and SEO-friendly URLs, improving the maintainability of your web application, and supporting more structured and organized code through the proper separation of concerns.

Attribute Routing: Using attributes, you may build routes directly on the controller and action methods. This method gives you more fine-grained control over single action routing and allows you to build unique routes for individual actions. When you have non-conventional URL patterns or want more descriptive URLs, attribute routing comes in handy.

In ASP.NET MVC, here’s an example of attribute routing:

// Controller with attribute routing
[RoutePrefix(“products”)]
public class ProductController : Controller
{
    [Route(“”)]
    public ActionResult Index()
    {
        // Action logic
    }
    [Route(“{id}”)]
    public ActionResult Details(int id)
    {
        // Action logic
    }
}

Area Routing: Areas are used in ASP.NET MVC to partition related portions of a web application into different modules. Controllers, views, and models can be customised for each region. Area-specific routing can be used with areas to control routes inside that specified area. When dealing with large and complex applications, this helps to maintain clean and organised code.

Custom Route Constraints: Custom route constraints let you specify extra requirements that a route must meet in order to be accepted as a match. Implementing the IRouteConstraint interface enables you to create unique route constraints. For instance, you can build a custom constraint to guarantee that the “id” argument adheres to a particular format or fits within a given range.

Catch-All Routes: Any URL that doesn’t match one of the other defined routes is matched using catch-all routes. When dealing with specific URL patterns that don’t suit the typical route patterns, this is useful.

With these multiple routing systems in ASP.NET MVC, you may handle a variety of URL patterns, create custom routes, and set up your application’s URLs anyway you see fit.

How to get a DOTNET Job abroad from India?

First approach is, do your own research and get ideas to grab the Job. This article will give you some ideas on how to start your job search.

Below are the ways to grab the job opportunity.

  • Networking

The community groups set up monthly technology meetup, that help peoples in the community to have a face to face connect. If you are a good speaker, you can take some technology seminars in the meet up and increase your visibility.

Get opportunity based on Language

There are few countries like Japan, Germany, China who prefer the candidates with good language skills. Japan prefers language certified candidates even though you are good in technology. Japanese language Proficiency Test has five levels N1, N2, N3, N4 and N5. The easiest level is N5 and the most difficult level is N1. In case you look out for a job in Japan, then studying these certifications will surely be an advantage.

Similar to Japanese language, German language also has its own scope in Job market. Even if you don’t have the proficiency to speak in German, holding a certificate will improve your chance to get a job in Germany. The level of competence in German is as below,

  • Levels A1 and A2
  • Levels B1 and B2
  • Levels C1 and C2

Levels A1 and A2 – These levels provide the basic level of German language.

Levels B1 and B2 – You will learn German at an advanced level

Levels C1 and C2 – You will master German at this level

For Chinese, Hanyu Shuiping kaoshi is an international standardized exam which tests and rates Chinese language proficiency. HSK certification will improve your probability for job search in China.

Get Job based on your technical skills

Always work on the trending technologies in software. Keep upskilling even in case if you work on old technology. Most of the onsite openings look out for trending technology.

Some of the recent trending technology in dotnet are as below,

  • Big Data with sql server
  • Asp.net Core
  • Tableau with sql server
  • Data Science
  • Artificial Intelligence
  • Selenium with C# .net

First, the overseas company look out for the candidate in local for any job opportunity.  If they can’t find any talent for that technology in local country, then they start their search in foreign country.

Being on the latest technology will increase your demand in the foreign job market. Recruiter in nearest country to India like UAE, Malaysia, Singapore extend their job search to India once they can’t find the right talent. Recruitment is mainly based on supply and demand. If the supply for the talent is not available within the country for a trending technology, then the demand rises and the recruiter starts looking outside country.

Pick good MNC companies in Offshore and travel abroad

Lot of companies in Chennai and Bangalore sends their employees to onsite for work. The company will take care of your visa process and place you in work in onsite. Every project in software works with few offshore resources and one or two onsite resources.  The offshore company have the capability to arrange for your visa based on the project requirement. The only harder thing, you should be chosen as the onsite resource by your manager.

If your manager recognizes you as the skillful talent, then this is the easiest way to travel abroad.

Register in portals like monster.com, LinkedIn

Register your resume in portals like Monster.com, LinkedIn. Foreign Recruiters looks out in these portal to hire candidates. Monster provides you a lot of job opportunities in Singapore and Malaysia.

Naukri provides you job opportunity in Dubai and other overseas countries. Update your resume with recent technology and certification details. Nowadays, few companies in Oman walks down to India and arrange Job interviews. You can also attend skype interviews from Singapore, Malaysian companies.

Linked in optimization also increase your visibility to the foreign recruiters to hire you. You can even apply for jobs in Linked in and keep connected with the recruiters.

Three Tier Architecture in MVC

Three Tier (Three Layer) Architecture

With a three-layer design, the project is divided into three layers: the user interface layer, the business layer, and the data layer (database), where we divide the UI, logic, and data into three groups. If a user wants to switch the user interface from a Windows computer to a smartphone, he or she simply needs to alter the UI layer; all other layers are unaffected. Like this, if a user wishes to change a database, he simply needs to update the data layer; everything else stays the same.

The widely used three-tier (or three-layer) architecture is a way to organise the codebase. This architecture divides the codebase into three distinct levels, each with a unique set of duties:

Presentation layer: This is the application’s user interface, which shows the user the features and data of the programme.

Business logic (or Application) layer: The business logic that powers the application’s essential features is contained in this layer. as processing the data moving between the other two layers and making judgements, calculations, and evaluations.

Data access layer (or Data) layer: To save and recover application data, this layer communicates with databases.

Advantages of using three-tier architecture are:

Accelerated development: Reducing product time to market and enabling developers to use the most current tools and layer appropriate languages.

Improved scalability:  By deploying apps on many levels, each tier may always be scaled separately.

Improved Reliability: By using several tiers, you may execute additional components of your application on other servers and employ results that have been cached to improve reliability and availability.

Enhance security: By using a well-designed application layer as a private firewall to help avoid receptive weaknesses like SQL injection.

The package of different layers is as follows.

  • Presentation Layer – controller package
  • Business Logic Layer – service package
  • Data Access Layer – repository package 

Three Layer Architecture using MVC Sample:

Create an empty MVC web application project with Project name “WebApp” and solution name “TLA”. This WebApp project is the presentation layer.

In Solution TLA, add a new project to create business logic à Class library (.net framewok) à name the project as BusinessLayer.

Again, in Solution TLA, add a new project to create data access à Class library (.net framewok) à name the project as DataBaseLayer.
Add BusinessLayer & DataBaseLayer as reference in “WebApp”.

Add BusinessLayer as reference in “DataBaseLayer”.

In sql server explorer, add a new database with name “MYDB” and create a table with name “Registration”.

CREATE TABLE [dbo].[Registration](
[RegId] [int] IDENTITY(1,1) NOT NULL,
[FullName] varchar NULL,
[Address] varchar NULL,
[Gender] varchar NULL,
[City] varchar NULL,
[DoB] [date] NULL,
[Cno] varchar NULL,
PRIMARY KEY CLUSTERED ([RegId] ASC)

In “DataBaseLayer”, add the model file using “ado.net entity data model”.

Once model is created, copy the connection string from app.config of “DataBaseLayer” and paste it in web.config of “WebApp”.

In “BusinessLayer”, create a class file with name “RegistrationModel” and replace with below snippet.

public class RegistrationModel
{
public int RegId { get; set; }
public string FullName { get; set; }
public string Address { get; set; }
public string Gender { get; set; }
public string City { get; set; }
public Nullable DoB { get; set; }
public string Cno { get; set; }
}

In “DataBaseLayer”, add a new folder with name “DBOperation”, in it, add a class file with name “ManageRegistration” and replace with below snippet.

public class ManageRegistration
{
public void AddReg(RegistrationModel regModel)
{
using (var DB = new MYDBEntities())
{
Registration Reg = new Registration()
{
FullName = regModel.FullName,
Address = regModel.Address,
Gender = regModel.Gender,
City = regModel.City,
DoB = regModel.DoB,
Cno = regModel.Cno
};
DB.Registrations.Add(Reg);
DB.SaveChanges();
}
}
}

Then add EntityFramework.dll and EntityFramework.SqlServer.dll references in “WebApp”.

So now the business layer and data layer has been completely created.

Now, in WebApp (i. e. in presentation layer), add a new controller with name “Home controller” and replace with below snippet.

public class HomeController : Controller
{
// GET: Home
public ActionResult Index()
{
return View();
}
ManageRegistration ManageReg = new ManageRegistration();
[HttpPost]
public void AddReg(FormCollection Form)
{
RegistrationModel registrationModel = new RegistrationModel()
{
FullName = Form["txtName"],
Address = Form["txtAddress"],
Gender = Form["rdbGender"],
City = Form["txtCity"],
DoB = Convert.ToDateTime(Form["txtDoB"]),
Cno = Form["txtCno"]
};
ManageReg.AddReg(registrationModel);
Response.Write("Saved");
}
}

Add index view with empty without model and put the below html and ajax snippet in it

Solid Principles in C#.net

In C#, the SOLID principles are a set of guidelines that help developers design software that is modular, maintainable, and extensible. SOLID is an acronym that stands for:

S – Single Responsibility Principle (SRP)

O – Open-Closed Principle (OCP)

L – Liskov Substitution Principle (LSP)

I – Interface Segregation Principle (ISP)

D – Dependency Inversion Principle (DIP)

Single Responsibility Principle (SRP):

A class should have only one reason to change. It states that a class should have only one responsibility or job. This principle helps to keep classes focused, maintainable, and easier to understand.

public interface INotificationService
{
void SendNotification(string message);
}
public class EmailNotificationService : INotificationService
{
public void SendNotification(string message)
{
// Code to send an email notification
}
}
public class SMSNotificationService : INotificationService
{
public void SendNotification(string message)
{
// Code to send an SMS notification
}
}
public class NotificationSender
{
private readonly INotificationService _notificationService;
public NotificationSender(INotificationService notificationService) { _notificationService = notificationService; } public void SendNotification(string message) { _notificationService.SendNotification(message); }
}

In this example, the FileManager class has the responsibility of reading and saving files, while the FileParser class is responsible for parsing files. Each class has a single responsibility, making it easier to understand and maintain.

Open-Closed Principle (OCP):

Software entities (classes, modules, functions, etc.) should be open for extension but closed for modification. This principle encourages designing modules that can be extended without modifying their existing code, reducing the risk of introducing bugs and making it easier to add new features.

public abstract class Shape
{
public abstract double CalculateArea();
}
public class Rectangle : Shape
{
public double Width { get; set; }
public double Height { get; set; }
public override double CalculateArea() { return Width * Height; }
}
public class Circle : Shape
{
public double Radius { get; set; }
public override double CalculateArea() { return Math.PI * Radius * Radius; }
}

In this example, the Shape class is open for extension, as new shapes can be added by creating new subclasses of Shape. The existing code is closed for modification, as the Shape class and its existing subclasses do not need to be changed when adding new shapes.

Liskov Substitution Principle (LSP):

Objects of a superclass should be able to be replaced with objects of their subclass without breaking the behavior of the system. In other words, derived classes should be substitutable for their base classes, and they should honor the contracts defined by the base class.

public class Vehicle
{
public virtual void Start()
{
Console.WriteLine(“Starting the vehicle”);
}
}
public class Car : Vehicle
{
public override void Start()
{
Console.WriteLine(“Starting the car”);
}
}
public class Motorcycle : Vehicle
{
public override void Start()
{
Console.WriteLine(“Starting the motorcycle”);
}
}

In this example, the Car and Motorcycle classes are subclasses of Vehicle, and they can be substituted for Vehicle without breaking the behavior of the system. The Start method is overridden in each subclass, providing specific implementations for starting a car and starting a motorcycle.

Interface Segregation Principle (ISP):

Clients should not be forced to depend on interfaces they do not use. This principle encourages the creation of small, specific interfaces instead of large general-purpose interfaces. It helps to avoid forcing clients to implement methods they don’t need and promotes decoupling and flexibility.

public interface IOrder
{
void ProcessOrder();
}
public interface IShipping
{
void ShipOrder();
}
public class OnlineOrder : IOrder, IShipping
{
public void ProcessOrder()
{
Console.WriteLine(“Processing online order”);
}
public void ShipOrder() { Console.WriteLine("Shipping online order"); }
}
public class OfflineOrder : IOrder
{
public void ProcessOrder()
{
Console.WriteLine(“Processing offline order”);
}
}

In this example, we have two interfaces: IOrder and IShipping. The OnlineOrder class implements both interfaces, as it can process an order and ship it. The OfflineOrder class only implements the IOrder interface because it doesn’t involve shipping. This segregation of interfaces ensures that classes only depend on the methods they actually need.

Dependency Inversion Principle (DIP):

High-level modules should not depend on low-level modules; both should depend on abstractions. Abstractions should not depend on details; details should depend on abstractions. This principle promotes loose coupling between modules, promotes modular design, and enables easier testing and maintainability.

public interface INotificationService
{
void SendNotification(string message);
}
public class EmailNotificationService : INotificationService
{
public void SendNotification(string message)
{
// Code to send an email notification
}
}
public class SMSNotificationService : INotificationService
{
public void SendNotification(string message)
{
// Code to send an SMS notification
}
}
public class NotificationSender
{
private readonly INotificationService _notificationService;
public NotificationSender(INotificationService notificationService) { _notificationService = notificationService; } public void SendNotification(string message) { _notificationService.SendNotification(message); }
}

In this example, the NotificationSender class depends on the INotificationService interface rather than concrete implementations. This allows different notification services to be injected at runtime, promoting loose coupling. The high-level module (NotificationSender) depends on the abstraction (INotificationService) rather than the low-level modules (EmailNotificationService, SMSNotificationService).

By adhering to these principles, developers can create code that is easier to understand, maintain, and modify, leading to more robust and scalable software systems.

C# Web API

C# Web API

Asp.net Web API is a framework that is provided by Microsoft and used to create HTTP services.

ASP.NET Web API is an easy-to-build HTTP web service. To reach a range of clients, including browsers, mobile applications, desktop applications, and IOTs.

The Asp.net web API has two layers.

 1.client layer

 2.server layer

It is accessed by a wide range of clients, including web browsers, mobile applications, and desktop applications, when the client layer makes a request to the web API to get an output response in different formats like JSON or XML.

Http Request = http://servername/apiname?id=101
Http Response = {“Name”,ABC,”Age”:”54”}

What is HTTP?  
HTTP – Hyper Text Transfer Protocol means the user gets a different device to get a request, but the output gets the same response server, also called HTTP.
HTTP Is used more than providing web page and also strong foundation for the developing API.
HTTP is a essential and pervasive protocol  

Why to choose ASP.NET Web API?

  • Web API is light weight framework for API Development
  • Web API has built-in support for standard formats like JSON and XML., and Other Formats.
  • Web API is a Content Negotiation
  • c#.net Web API maps HTTP Verbs to method names

Features of Web API

Filter: It gives filters to the web application.
Action Result: It can keep the action logos client, such as information recovery.
Routing: It makes a difference in routing through different APIs.
Controller: It gives useful capabilities to the web application.
Model: It gives the basic capabilities of the web application.  

Types of Web API in C#

  1. public
  2. partner
  3. private
  4. Composite

Public APIs 

 A public API is open and available for use by outside developers or businesses; its application, Data, will develop and offer a public API. also called public APIs or external APIs.

Partner APIs

Partner APIs can interface the internal client information system with those outside groups no other APIs are allowed. APIs are generally stronger authentication, authorization, and security machines.

private APIs

Private APIs are used by enterprises to connect system and data APIs for internal use at certain security levels.

Composite APIs

Composite APIs generally combine two or more APIs’ interdependent operations. Composite APIs sometimes improve speed and performance.

SQL Job Support in India

SQL Overview:

SQL is a database management language that includes database creation, database deletion, fetching data rows, modifying, and deleting data rows, and so on.

SQL stands for Structured Query Language, and it is a computer language used to store, manipulate, and retrieve data from relational databases. SQL was created by IBM Computer Scientists in the 1970s and was adopted as a standard by the American National Standards Institute (ANSI) in 1986 and the International Organization for Standardization (ISO) in 1987.

SQL is the industry standard for communicating with Relational Database Systems. SQL is the Standard Database Language used by all Relational Database Management Systems (RDMS) such as MySQL, MS Access, Oracle, Sybase, Informix, Postgres, and SQL Server.

Data is everything nowadays. To comprehend this, you must be familiar with data management. SQL is a language that can be used to understand databases. SQL (Structured Query Language) is the name given to a language used to communicate with databases. The SQL language can be used to edit, pull, and add information to a database. SQL is the foundation of relational databases. More information is available in our SQL online job support.

SQL is widely used because it provides the following benefits:

Users can

  • access data stored in relational database management systems.
  • describe the data.
  • define and manipulate data in a database.
  • create and delete databases and tables.
  • create views, stored procedures, and functions in a database.
  • assign permissions to tables, procedures, and views.
  • embed SQL modules, libraries, and pre-compilers within other languages.

Stored Procedure in SQL Server

  • A stored procedure is a precompiled and stored database object that contains a set of SQL statements and procedural logic that can be executed as a single unit. It can be used in a database management system to simplify complex queries and database operations. It is a prepared SQL code that you can save, so the code can be reused over and over again. Stored procedures help improve performance and security, as well as simplify the code.

Here’s a basic example of a stored procedure that accepts two input parameters and returns the sum of those two numbers:

CREATE PROCEDURE AddNumbers
@n1 INT,
@n2 INT
AS
BEGIN
SET NOCOUNT ON;
SELECT @n1 + @n2 AS ‘Sum’;
END  

In this example, CREATE PROCEDURE is used to define the name of the procedure (AddNumbers) and its input parameters (@n1 and @n2). The AS keyword is used to begin the code block for the stored procedure.

SET NOCOUNT ON is used to prevent the count of the number of rows affected by the stored procedure from being returned.

The code block then calculates the sum of the two input parameters and returns the result using the SELECT statement.

Once the stored procedure is defined, it can be executed by calling its name:

EXEC AddNumbers 2, 3;

This will return the result 5 as the sum of 2 and 3.

Stored Procedure in a Basic CRUD Operation

Now, let us have an idea about using stored procedure in a basic CRUD operation sample.

Let us create a database as follows:

Create database Company

Then create a table in the corresponding database.

CREATE TABLE Employee(
EmpCode int,
EmpName nchar(100),
EmpAge int,
EmpSal int)

Inserting data into a table: This stored procedure inserts a new employee record into a table named Employee:

CREATE PROCEDURE AddEmployee
@EmpCode int,
@EmpName nchar(100),
@EmpAge int,
@EmpSal int
AS
BEGIN
SET NOCOUNT ON;
INSERT INTO Employee(EmpCode, EmpName, EmpAge, EmpSal)
VALUES (@EmpCode, @EmpName, @EmpAge, @EmpSal);
END

On executing the above snippet, a stored procedure to add the details in the table will be created.

Now, by calling the below query, the table will get added the following 5 datas.

EXEC AddEmployee 1, ‘TOM’, 25, 30000
EXEC AddEmployee 2, ‘RAM’, 25, 30000
EXEC AddEmployee 3, ‘RAJA’, 26, 32000
EXEC AddEmployee 4, ‘SIVA’, 26, 32000
EXEC AddEmployee 5, ‘GOPI’, 25, 30000

Retrieving data from a table: This stored procedure retrieves all the rows from a table named Employee:

CREATE PROCEDURE GetEmployees
AS
BEGIN
SET NOCOUNT ON;
SELECT * FROM Employee;
END

On executing the above snippet, a stored procedure to get the employee details from the table will be created.

Then by simply calling the below query, the datas stored in the table can be retrieved.

EXEC GetEmployees

Updating data in a table: This stored procedure updates an existing employee record in a table named Employee:

CREATE PROCEDURE UpdateEmployee
@EmpCode int,
@EmpName nchar(100),
@EmpAge int,
@EmpSal int
AS
BEGIN
SET NOCOUNT ON;
UPDATE Employee SET
EmpName = @EmpName,
EmpAge = @EmpAge,
EmpSal = @EmpSal
WHERE EmpCode = @EmpCode;
END

On executing the above snippet, a stored procedure to update the details in the table will be created.

Now, by calling the below query, the data with “EmpCode =1” in the table can be updated with new data as follows.

EXEC UpdateEmployee 1, ‘Jerry’, 26, 32000

Deleting data from a table: This stored procedure deletes an existing employee record from a table named Employee:

CREATE PROCEDURE DeleteEmployee
@EmpCode int
AS
BEGIN
SET NOCOUNT ON;
DELETE FROM Employee
WHERE EmpCode = @EmpCode;
END

On executing the above snippet, a stored procedure to delete the details in the table will be created.

Now, by calling the below query, the data with “EmpCode=1” in the table can be deleted

EXEC DeleteEmployee 1

These are just a few examples, and there are many more possibilities for what you can do with stored procedures.

Securing ASP.NET Core web application with Identity Framework

Securing ASP.NET Core web application with Identity Framework:

Web application security is more important than ever in today’s world. Identity Framework is one of the tools and features available in ASP.NET Core for securing web applications. Identity Framework is a membership system that provides the user interface, APIs, and features required for the creation and management of user accounts.

In this article, we’ll go over how to use Identity Framework to secure your ASP.NET Core web application.

Step 1: ASP.NET Core Web Application Creation:

The first step is to build an ASP.NET Core web app. You can accomplish this by taking the following steps:

Launch Visual Studio and select “New Project.”

Click “Next” after selecting “ASP.NET Core Web Application.”

Select a project template (such as MVC, Web API, or Razor Pages) and click “Create.”
Step 2: Identity Framework Installation:

Following the creation of the ASP.NET Core web application, the Identity Framework must be installed. You can accomplish this by including the following package in your project:

Microsoft.AspNetCore.Identity.EntityFrameworkCore

You can install this package using the NuGet Package Manager or by adding the following line to your.csproj file:

<PackageReference Include=”Microsoft.AspNetCore.Identity.EntityFrameworkCore” Version=”2.2.0″ />

Step 3: Identity Framework Configuration:

The following step is to set up Identity Framework. You can accomplish this by including the following code in the Startup.cs file’s ConfigureServices method:

services.AddIdentity<IdentityUser, IdentityRole>()

    .AddEntityFrameworkStores<ApplicationDbContext>()

    .AddDefaultTokenProviders();

This code instructs Identity Framework to use the IdentityUser and IdentityRole classes as the user and role entities, respectively, as well as the ApplicationDbContext as the database context.

Step 4: Database Creation:

The database will be created next. You can do this by running the following command in the Package Manager Console:

Update-Database

This command will populate the database with the necessary tables.

Step 5: Implement of Authentication and Authorization

The final step is to put authentication and authorization in place. This is accomplished by appending the [Authorize] attribute to the controllers or actions that require authorization. Policies can also be used to implement more complex authorization requirements.

Identity Framework’s SignInManager and UserManager classes can be used to implement authentication.

In Conclusion, we have discussed how to use Identity Framework to secure your ASP.NET Core web application in this article. We went over the steps for developing an ASP.NET Core web application, installing and configuring the Identity Framework, creating the database, and implementing authentication and authorization. You can create a secure ASP.NET Core web application that protects your users’ data and privacy by following these steps.

Differences between ASP.NET Core and ASP.NET Framework

ASP.NET Core and ASP.NET Framework are both web application frameworks developed by Microsoft, but there are some significant differences between the two. Here are some of the key differences between ASP.NET Core and ASP.NET Framework:

  • Open-source and community-driven: ASP.NET Core is open-source and community-driven, with contributions from developers around the world. ASP.NET Framework is also open-source, but Microsoft is the primary contributor.
  • Cross-platform support: ASP.NET Core is designed to be cross-platform and can run on Windows, macOS, and Linux. ASP.NET Framework, on the other hand, is designed to run only on Windows.
  • Modular design: ASP.NET Core has a modular design, with a lightweight and customizable architecture that allows developers to choose only the components they need. ASP.NET Framework has a monolithic design and includes a large set of pre-built components, which can result in larger and slower applications.
  • Performance: ASP.NET Core is optimized for performance and can handle a larger number of requests per second than ASP.NET Framework. This is due to its lightweight design, which reduces overhead and allows it to run more efficiently.
  • Dependency Injection: ASP.NET Core includes built-in support for Dependency Injection, which makes it easier to manage dependencies and improve code maintainability. ASP.NET Framework does not include built-in support for Dependency Injection, although it is possible to implement it using third-party libraries.
  • Target platforms: ASP.NET Core is designed to target multiple platforms, including cloud, mobile, and desktop, while ASP.NET Framework is primarily targeted at web applications.

In summary, ASP.NET Core and ASP.NET Framework are both powerful web application frameworks, but they have some significant differences in terms of cross-platform support, open-source and community-driven development, modular design, performance, and target platforms. The choice between the two depends on the requirements of the project and the preferences of the developer.

Differences between ASP.NET Web Forms and ASP.NET MVC

ASP.NET Web Forms and ASP.NET MVC are two popular frameworks for building web applications in ASP.NET. Although both are built on the same platform and provide similar functionality, they have some key differences that set them apart. Here are some of the main differences between ASP.NET Web Forms and ASP.NET MVC:

  • Separation of Concerns: ASP.NET Web Forms allows mixing of markup (HTML) and code (C# or VB.NET) in the same file, which can make it difficult to maintain the code. ASP.NET MVC separates the markup and code into different files, which makes it easier to maintain the code.
  • Architecture: ASP.NET Web Forms uses a Page Controller architecture, where a single page contains all the code to handle the request and response. ASP.NET MVC, on the other hand, uses a Front Controller architecture, where a controller handles all the requests and responses for a group of pages.
  • Testability: ASP.NET MVC is more testable than ASP.NET Web Forms, as it separates the code and markup, making it easier to write automated tests.
  • URL Routing: ASP.NET Web Forms does not have built-in URL routing support, which can make it difficult to create search engine friendly URLs. ASP.NET MVC has built-in support for URL routing, which makes it easier to create clean and search engine friendly URLs.
  • View State: ASP.NET Web Forms uses View State to maintain the state of controls on the page. This can result in large amounts of data being sent back and forth between the server and client, which can impact the performance of the application. ASP.NET MVC does not use View State, which can improve the performance of the application.

In summary, both ASP.NET Web Forms and ASP.NET MVC are powerful frameworks for building web applications in ASP.NET. The choice between them depends on the requirements of the project and the preferences of the developer. If you need more control over the markup and want to create search engine friendly URLs, ASP.NET MVC may be the better choice. If you need a rapid application development tool and are comfortable with the Page Controller architecture, then ASP.NET Web Forms may be the better choice.

ENTITY FRAMEWORK


What is Entity Framework?
We (developers) used to frequently write ADO.NET code or Enterprise Data Access Block in Dot NET 3.5 to save or retrieve application data from the underlying database. Microsoft has provided a framework called “Entity Framework” to automate all these database-related activities for your application. Entity Framework is a Microsoft-supported open-source ORM framework for.NET applications. It enables developers to work with data using objects of domain-specific classes without focusing on the underlying database tables and columns where this data is stored.

Entity Framework in C#:
In this article, we will see how to use Entity Framework in C# applications using Visual Studio. The examples in this and likely future articles will use C# under Win Forms, but as previously stated, this choice will not affect a different intended use that the developer may reasonably request.

ORM in C#:
Optical mark recognition (also called optical mark reading or OMR) is the process of using hardware, software, or both to capture fields, for example, marks on documents such as multiple-choice questions, questionnaires with true or false fields, and other document forms.


Types of ORM Fields:

There are numerous types of OMR fields, but this section will give an overview of some of the most common ones. There can be shapes like squares, circles, and ovals.

Why Entity Framework in .NET Applications?
 Entity Framework is an ORM tool, and ORM tools are primarily used to boost developer productivity by eliminating the redundant task of performing CRUD operations against a database in a.NET application.
 Entity Framework can generate the necessary database commands for doing the database CRUD operation, i.e., can generate select, insert, update, and delete commands for us.
 While working with Entity Framework, we can perform different types of operations on the domain objects (basically classes representing database tables) using LINQ to entities.
 Entity Framework will generate and execute the SQL command in the database and then store the results in the instances of your domain objects so that you can do different types of operations on the data.

Prerequisites to Learn Entity Framework:
To fully benefit from this Entity Framework Course, you should have a basic understanding of C# as well as any database such as SQL Server, Oracle, or MySQL. It is recommended that you install the.NET Framework, Visual Studio, and SQL Server on your computer.

Advantages of Entity Framework:
Productivity:
Entity Framework can take up to 35 percent of the entire application code. It makes the developer’s life easier than ever. Despite its limitations, the designer integrated into Visual Studio dramatically simplifies the mapping process.
Maintainability:
Since you have fewer lines of code to fetch data from the database, the fewer lines of code you have to maintain.
Performance:
The complexity of ORM introduces an obvious slowdown in performance. In the entity framework first request to fetch data is a little bit slow but after that is fast to fetch data from the database.
Transactions:
ORM does all possible automation as transactions while querying the data or storing the data periodically. We can also customize transaction management practices to make the most of it out of the entity framework.

ASP.NET Core:

ASP.NET Core – Introduction

ASP.NET Core is a free and open-source platform for creating high-performance online applications. It was meant to be lightweight, modular, and highly scalable, making it a popular choice for developers looking to construct online applications rapidly and effectively. In this post, we’ll look at ASP.NET Core and why it’s such a popular choice for developing online apps.

As the successor to the ASP.NET framework, ASP.NET Core was originally published in 2016. One of the key aims of ASP.NET Core was to build a cross-platform framework that could operate on Windows, Linux, and macOS. This was accomplished by building ASP.NET Core as a modular system, with various components that could be added or deleted as needed.

One of the most important characteristics of ASP.NET Core is its ability to operate on many platforms. The usage of.NET Core, a cross-platform version of the.NET runtime, enables this. This implies that developers may create web applications with the same codebase and run them on multiple operating platforms without changing anything.

Support for current web development approaches is another aspect of ASP.NET Core. ASP.NET Core has support for major client-side frameworks including Angular, React, and Vue. This enables developers to design complex, responsive web apps that deliver an excellent user experience.

ASP.NET Core also provides outstanding speed and scalability. The framework is intended to be quick and efficient, with low memory utilisation and quick startup times. It also has caching and load balancing features, making it simple to expand web applications to meet huge traffic.

ASP.NET Core includes a large ecosystem of tools and frameworks in addition to these functionalities. This includes Microsoft Visual Studio, a popular IDE for developing web applications, as well as a variety of open-source modules for everything from authentication to database access.

Overall, ASP.NET Core provides a strong framework for developing contemporary online apps. It is a popular choice among developers because to its support for cross-platform development, current web development methods, and good performance and scalability. If you want to develop online apps fast and effectively, ASP.NET Core is a great option.

Advantages on ASP.NET Core:

ASP.NET Core is a cutting-edge, cross-platform web development framework that has several benefits over other web development frameworks. In this post, we’ll look at some of the primary benefits of developing websites using ASP.NET Core.

Open-Source and Community-Driven:

ASP.NET Core is an open-source framework with a big and active development community. This implies that there are several libraries and tools available to assist developers in creating more efficient web apps. It also implies that there is an abundance of community assistance, such as online forums, blogs, and tutorials.

Cross-Platform Support:

One of the most significant advantages of ASP.NET Core is its ability to operate on different platforms, including Windows, Linux, and macOS. The usage of.NET Core, a cross-platform version of the.NET runtime, enables this. This enables developers to create web applications with the same codebase and run them on multiple operating systems with no modifications.

High Performance:

ASP.NET Core is intended to be quick and efficient, with low memory utilisation and quick startup times. It has a lightweight and modular design, allowing for increased performance and scalability. This makes it a good choice for developing online apps that must manage large traffic and respond quickly.

Modern Web Development Practices:

Modern web development approaches, such as client-side frameworks like Angular, React, and Vue, are embedded into ASP.NET Core. This enables developers to design responsive and dynamic web apps that deliver an excellent user experience. Tag helpers, which ease the process of creating HTML forms, and middleware, which provides a flexible and composable approach to handle requests, are also included in ASP.NET Core.

Security:

ASP.NET Core has a number of security capabilities that aid in the protection of online applications against typical threats like as cross-site scripting (XSS) and cross-site request forgery (CSRF). Built-in HTTPS support and the ability to encrypt sensitive data are among these features. It also contains login and authorisation tools that make controlling access to various portions of a web application simple.

In conclusion, ASP.NET Core provides several benefits for online development, including cross-platform compatibility, high performance, current web development standards, security features, and an active and friendly community. If you want to create contemporary, high-performance online apps, ASP.NET Core is a great option.

Partial View in MVC – ASP.NET

Partial View in MVC:

In ASP.NET MVC, a partial view is a special view that renders only a portion of the view content. It’s similar to a web form application’s user control. Partial can be reused in different views. It aids us in reducing code duplication. To put it another way, a partial view allows us to render a view within the parent view.

The partial view is implemented with its own copy of the parent view’s ViewDataDictionary object, so that the partial view can access the parent view’s data. The parent view’s data is unaffected if we change this data (ViewDataDictionary object). When related data that we want to render in a partial view is part of our model, we generally use the Partial rendering method of the view.

A partial view is a Razor markup file (.cshtml) without a @page directive that renders HTML output within the rendered output of another markup file.

When developing an MVC app, where markup files are called views, or a Razor Pages app, where markup files are called pages, the term partial view is used. This topic refers to MVC views and Razor Pages pages as markup files in general.

Difference between view and partial view in MVC: View is a complete markup that may include a master view (or master page) with all the design(s), whereas partial view is only a portion of the page or a small markup that does not include a master page. It is primarily used as a user control in mvc and can be applied to multiple views.

When to use partial views

Partial views are a useful technique when:

  • Large markup files should be divided into smaller parts. i.e. There is a benefit to working with each logical item separately in a partial view when working with a large, sophisticated markup file that is divided into numerous logical sections. Because the markup only provides references to partial views and the overall page structure, it is possible to handle the code in the markup file.
  • Reduce the amount of common markup content that is duplicated across markup files. i.e. When the same markup elements are used in multiple markup files, a partial view consolidates the markup content into a single partial view file. When the markup in the partial view is changed, the rendered output of the markup files that use the partial view is updated.

Note:

Partial views should not be used to keep common layout elements in place. _Layout.cshtml files should contain common layout elements.

When complex rendering logic or code execution is required to render the markup, do not use a partial view. Use a view component instead of a partial view in such cases.

How to Declare partial views

The names of partial views frequently begin with an underscore (_). This naming convention is optional, but it aids in visually distinguishing partial views from views and pages.

A partial view is a.cshtml markup file that is kept in the Views folder (MVC) or Pages folder(Razor Pages) but does not contain a @page directive

A controller’s ViewResult in ASP.NET Core MVC can return a full view or a partial view. A PageModel can return a partial view in Razor Pages that is represented as a PartialViewResult object. The Reference a partial view section goes over rendering and referencing partial views.

SQL Server Joins

SQL JOIN

The statement JOIN is used to combine the rows of two or more tables based  on a common column.

The different types of JOIN statement used in SQL are

  • INNER JOIN or JOIN – combines the data that matches  in both tables.
  • LEFT JOIN or LEFT OUTER JOIN – combines all the datas of left table with the datas from right table that matches.
  • RIGHT JOIN or RIGHT OUTER JOIN – combines all the datas of right table with the datas from left table that matches.
  • FULL JOIN or FULL OUTER JOIN – combines all the datas either from left or right table whenever there is a match found.

Let us consider an example:

Create a database with a name “StudentResults”

create database  StudentResults

Create a table “studentdetails” with following snippet

CREATE TABLE studentdetails (

regno int,

LastName varchar(255),

FirstName varchar(255),

age int,

dummyno int

);

Let us consider the following datas in table “studentdetails”

Create another table “result” with the snippet

CREATE TABLE result (

dummyno int,

marks int,

result varchar(10)

);

Let us consider the following datas in table “result”

 

INNER JOIN:

Inner Join is the most simplest Join. When inner join keyword is used in two tables, it will create a resulting table with combining the rows of both the tables until the condition is satisfied

For the above considered example, when inner join statement is used as follows

SELECT studentdetails.regno, studentdetails.FirstName, studentdetails.LastName, studentdetails.age, result.marks, result.result

FROM result

INNER JOIN studentdetails

ON studentdetails.dummyno=result.dummyno;

The resulting table will be

LEFT JOIN:

 Left join is also called as Left outer join. When left join keyword is used in two tables, it will create a resulting table with combining all the datas of left table with the datas from right table that matches.

For the considered example, when left join statement is used as follows

SELECT studentdetails.regno, studentdetails.FirstName, studentdetails.LastName, studentdetails.age, result.marks, result.result

FROM studentdetails

LEFT JOIN result

ON studentdetails.dummyno=result.dummyno

ORDER BY studentdetails.regno;

The resulting table will be

RIGHT JOIN:

 Right join is also called as right outer join. When right join keyword is used in two tables, it will create a resulting table with combining all the datas of right table with the datas from left table that matches.

For the considered example, when right join statement is used as follows

SELECT studentdetails.regno, studentdetails.FirstName, studentdetails.LastName, studentdetails.age, result.marks, result.result

FROM studentdetails

RIGHT JOIN result

ON studentdetails.dummyno=result.dummyno

ORDER BY studentdetails.regno;

The resulting table will be

FULL JOIN:

 Full join is also called as Outer join. When full join keyword is used in two tables, it will create a resulting table with combining all the datas either from left or right table whenever there is a match found.

For the considered example, when full join statement is used as follows

SELECT studentdetails.regno, studentdetails.FirstName, studentdetails.LastName, studentdetails.age, result.marks, result.result

FROM studentdetails

FULL OUTER JOIN result

ON studentdetails.dummyno=result.dummyno

ORDER BY studentdetails.regno;

The resulting table will be

ASP.NET Vs ASP.NET Core

ASP.NET:

ASP.NET is a basic web development tool designed and developed by Microsoft, it is used to create windows applications, websites, and web services. There are around 60 programming languages available on the ASP.NET platform, among which VB.Net and C# are mostly used.

ASP.NET Core

ASP.NET Core is a new version of ASP.NET, which was also released by Microsoft. It is a free, open source, general-purpose development tool used to develop modern cloud-based software applications on Windows or Linux or mac operating systems. It was launched as a version of ASP.NET (i. e ASP.NET 5) and later it was renamed as ASP.NET Core.

Table: difference between ASP.NET and ASP.NET Core:

ASP.NET 

ASP.NET Core

Only some components of the ASP.NET Framework are open source.

ASP.NET Core is completely a free and open-source tool.

It runs only on ASP.NET Framework.

It runs on ASP.NET Core and ASP.NET Framework.

Performance is good.

Performance is very high than ASP.NET.

ASP.NET Framework is compatible only with the Windows operating system.

ASP.NET Core is compatible with various operating systems — Windows, Linux, and Mac OS.

It Supports Web-Forms, MVC and Web API.

C#, VB, and many other languages can be used.

 C# and F# languages are only supportable.

All major versions supported.

Whenever we modify or update a code, we need to re-compile the program.

Whenever we modify or update a code, the Core Browser refresh will compile and execute the program itself, So no need to re-compile it again.

It is not suitable for any mobile application development. But used for the development of both desktop and web applications.

It is not suitable for desktop application development, but suits well for development of web, windows mobile and windows store.

In case of mobile applications, it can be used on devices which work on android and windows OS, Xamarin’s tools is used to configure such mobile applications.

It is installed as a single package for Windows OS.

As it is cross-platform, it is packaged and installed individually depending on the operating system used.

ASP.NET Framework is heavy for Command Line Interface (CLI).

ASP.NET core gives a lightweight CLI.

Code access security is available for security purposes.

No such security features available.

 

Summary:
If your application

  • is to be designed to run only on Windows
  • uses only the technologies of ASP.NET framework and if it does not support the technology of ASP.NET Core
  • is already running on ASP.NET Framework

Then it is better to choose ASP.NET Framework.

 If you are

  • developing a new application and have a choice to choose between ASP.NET Core or ASP.NET Framework
  • Targeting for microservices applications
  • in need of a tool with features such as cross-platform, high performance, and scalability

Then ASP.NET Core is best choice.

 The ASP.NET Core has the following advantages in comparison to ASP.NET Framework

  • Open Source
  • Cross-Platform
  • High Performance
  • Multiple development platform
  • Multi environmental modes

 

Subquery in SQL

Query: A query is a request for data or information from one or more tables of a database.

Sub Query: In SQL language, we can place a Query inside another Query. This Query which is placed inside another query is called as subquery, also known as Nested Query

Subqueries can be used with SELECT, UPDATE, INSERT, DELETE statements along with the equality operator or comparison operator such as =, >, =, <= and Like operator.

Subquery must be enclosed in parentheses.

An ORDER BY command cannot be used in a subquery, but the main query can use an ORDER BY. The GROUP BY command can be used instead of ORDER BY in a subquery.

 

Subquery – SELECT Statement

Consider a Query

Select * from StudentDetails

When this query when executed, selects all rows of the table

Now consider an example with subquery Select

Select * from StudentDetails

where ID in (Select ID from StudentDetails where Percentage > 90);

When this set of queries gets executed,

Always the subquery gets executed first, selects the ID from StudentDetails table whose percentage is greater than 90, And then the outer query gets executed later, selecting the ID equal to the result of subquey

 

Subquery – INSERT Statement

Now consider an example with subquery Insert

Insert into StudentDetails_new

Select * from StudentDetails where ID in (Select ID from StudentDetails );

Here a new table with StudentDetails_new is created with the same structure as StudentDetails table, now to copy the datas of StudentDetails table to StudentDetails_new table , insert  statement can be used.

 

Subquery – UPDATE Statement

Now consider an example with subquery update

update StudentDetails

Set mark = mark + 5

Where mark in (Select mark from StudentDetails where mark >= 91);

Here in the table StudentDetails, the mark can be updated with a bonus of 5 marks for those who have scored mark of 91 and above using this update statement.

 

Subquery – DELETE Statement

Now consider an example with subquery delete

Delete from StudentDetails

Where mark in (Select mark from StudentDetails where mark < 50);

Here in the table StudentDetails, the datas with marks less than 50 can be removed using delete statement.
