Entity Framework Tutorial with MVC
Entity Framework (EF) is an object-relational mapper that enables .NET developers to work with relational data using domain-specific objects. It eliminates the need for most of the data-access code that developers usually need to write.
Entity framework is useful in three scenarios. First, if you already have existing database or you want to design your database ahead of other parts of the application.
Second, you want to focus on your domain classes and then create the database from your domain classes.
Third, you want to design your database schema on the visual designer and then create the database and classes.
