    Entity Framework is an object-relational mapper (O/RM) that enables .NET developers to work with a database using.NET objects. It eliminates the need for most of the data-access code that developers usually need to write.Entity Framework Features:Cross-platform: EF Core is a cross-platform framework which can run on Windows, Linux and Mac.Modelling: EF (Entity Framework) creates an EDM (Entity Data Model) based on POCO (Plain Old CLR Object) entities with get/set properties of different data types. It uses this model when querying or saving entitydata to the underlying database.Querying: EF allows us to use LINQ queries (C#/VB.NET) to retrieve data from the underlying database. The database provider will translate this LINQ queries to the database-specific query language (e.g. SQL for a relational database). EF also allows us to execute raw SQL queries directly to the database.Entity framework latest version is EF6 then entity framework core launched and its latest version is EF core 2.0.The context class in Entity Framework is a class which derives from DbContext in EF 6 and EF Core both.It is an important class in Entity Framework, which represents a session with the underlying database.

    Entity Framework was first released in 2008, Microsoft's primary means of interacting between .NET applications and relational databases. Entity Framework is an Object Relational Mapper (ORM) which is a type of tool that simplifies mapping between objects in your software to the tables and columns of a relational database.Entity Framework (EF) is an open source ORM framework for ADO.NET which is a part of .NET Framework.An ORM takes care of creating database connections and executing commands, as well as taking query results and automatically materializing those results as your application objects.An ORM also helps to keep track of changes to those objects, and when instructed, it will also persist those changes back to the database for you.

    Entity Framework is an open-source ORM framework for .NET applications supported by Microsoft. 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. With the Entity Framework, developers can work at a higher level of abstraction when they deal with data and can create and maintain data-oriented applications with less code compared with traditional applications.Official Definition: “Entity Framework is an object-relational mapper (O/RM) that enables .NET developers to work with a database using .NET objects. It eliminates the need for most of the data-access code that developers usually need to write.”

    There are some differences between Entity Framework and LINQ to SQL. 1 Entity framework has a full provider model. It supports not only SQL Server but also other database like Oracle, DB2, MySQL etc. ? Most of the time LINQ to SQL classes must be one-to-one with database objects e.g. Customer class can be mapped only with Customer table. Where as in Entity Framework you can map your domain class with multiple tables using various inheritance strategies like table per type (class) or table per hierarchy of classes etc. 2 You can have multiple modeling techniques using Entity Framework 4.1 like code first, model first or database first. 3 Microsoft has long term strategy to support and integrate Entity Framework with multiple Microsoft products.
