Microsoft has provided a framework called &#8220;Entity Framework&#8221; 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.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full is-resized\"><img fetchpriority=\"high\" decoding=\"async\" src=\"https:\/\/www.softwaretraininginchennai.com\/blog\/wp-content\/uploads\/2023\/02\/Picture1-1.png\" alt=\"\" class=\"wp-image-677\" width=\"334\" height=\"351\"\/><\/figure>\n\n\n\n<p><\/p>\n\n\n\n<p><strong>Entity Framework in C#:<\/strong><br>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.<\/p>\n\n\n\n<p><\/p>\n\n\n\n<p><strong>ORM in C#:<\/strong><br>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.<\/p>\n\n\n\n<p><br><strong>Types of ORM Fields:<\/strong><\/p>\n\n\n\n<figure class=\"wp-block-image size-full is-resized\"><img decoding=\"async\" src=\"https:\/\/www.softwaretraininginchennai.com\/blog\/wp-content\/uploads\/2023\/02\/Picture2.png\" alt=\"\" class=\"wp-image-676\" width=\"460\" height=\"148\" srcset=\"https:\/\/www.softwaretraininginchennai.com\/blog\/wp-content\/uploads\/2023\/02\/Picture2.png 302w, https:\/\/www.softwaretraininginchennai.com\/blog\/wp-content\/uploads\/2023\/02\/Picture2-300x96.png 300w\" sizes=\"(max-width: 460px) 100vw, 460px\" \/><\/figure>\n\n\n\n<p>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.<\/p>\n\n\n\n<p><\/p>\n\n\n\n<p><strong>Why Entity Framework in .NET Applications?<\/strong><br>\uf0d8 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.<br>\uf0d8 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.<br>\uf0d8 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.<br>\uf0d8 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.<\/p>\n\n\n\n<p><\/p>\n\n\n\n<p><strong>Prerequisites to Learn Entity Framework:<\/strong><br>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.<\/p>\n\n\n\n<p><\/p>\n\n\n\n<p><strong>Advantages of Entity Framework:<\/strong><br><em>Productivity:<br>Entity Framework can take up to 35 percent of the entire application code. It makes the developer\u2019s life easier than ever. Despite its limitations, the designer integrated into Visual Studio dramatically simplifies the mapping process.<br>Maintainability:<br>Since you have fewer lines of code to fetch data from the database, the fewer lines of code you have to maintain.<br>Performance:<br>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.<br>Transactions:<br>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.<\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>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.
