Introduction to Entity Framework

A .NET assembly is the main building block of the .NET Framework. It is a small unit of code that contains a logical compiled code in the Common Language infrastructure (CLI), which is used for deployment, security and versioning. It defines in two parts (process) DLL and library (exe) assemblies. When the .NET program is compiled, it generates a metadata with Microsoft Intermediate Language, which is stored in a file called Assembly. I updated the connection string in my web.config file located in the root directory of the web application. This article discusses how we can use EF Core with an in-memory database in an ASP.NET Core 6 application.

  • From our next article onwards, I am going to explain everything in detail.
  • The Entity Framework is an Object/Relational Mapping (O/RM) framework that maps objects to relational databases.
  • You may think of traditional SQL Queries and ADO.NET approaches to achieve the task.
  • Entity Framework is an open-source object-relational mapper framework for .NET applications supported by Microsoft.
  • Tables are mapped to classes and columns are mapped to class properties.

By definition, we now have the means to interact with Student Entity. I will create a Student Model in the Models folder, and add a bunch of properties to it. We will use this class as the base class for our future entities. Here we can define the common and secured properties like Id, CreatedDate, etc. For this demonstration, we will be using SQLServer as our database provider.

Types of Entities in Entity Framework

Now that we have finished setting up the bare minimum, let’s configure our ASP.NET Core Application to support Entity Framework Core and set up Swagger as well. Go to your Startup class and modify the ConfigureServices method as below. In the next article, I am going to discuss How to Install the Entity Framework Core in ASP.NET Core Application what is entity framework using Visual Studio. Here, I briefly introduced Entity Framework Core in this article, and I hope you enjoy this Introduction to Entity Framework Core article. ORMs Tools are used to increase the developer’s productivity by reducing the redundant task of doing CRUD operations against a database in a .NET Core (.NET) Application.

In this section, we will understand the .NET Framework, characteristics, components, and its versions. Every corner I turn, and blog I read pertaining to .net, and in particular, c# – I’ve noticed an overwhelming recommendation for ORMs, and of those, Entity Framework seems to take the cake.

Versions of .NET Framework

Out of the box, in the Code-First Approach, the EF Core API creates the database and tables using migration based on the default conventions and configuration. You can change the default conventions used to create the database and its related tables if you want. In this scenario, the same context class is used to retrieve and save entities. It keeps track of all databases during the whole lifecycle.

This folder contains some auto generated files like Index, Create, Delete etc. To leverage the in-memory capabilities of EF Core in your application, you should add the Microsoft.EntityFrameworkCore.InMemory package to your project. Another downside is that an in-memory database uses much more memory compared to a traditional database that resides on a physical disk (and memory is far more expensive than disk storage).

The .NET Framework is a software development platform that was introduced by Microsoft in the late 1990 under the NGWS. On 13 February 2002, Microsoft launched the first version of the .NET Framework, referred to as the .NET Framework 1.0. I have an application in ASP.NET Core-6 Web API using Entity Framework, and also utilizes code first data migration. A new StudentsController has added that contains some auto generated code as given below.
