Entity Framework

"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." - Microsoft

Installing the Entity Framework
You can go to the MSDN site and install the framework from here.  You can also do it using the Package Installer built-in with Visual Studio.

1. Open a project in Visual Studio.
2. Go to Tools > Library Package Manager > Package Manager Console
3. In the command window type install-package entityframework and hit enter.
4. The rest of the work is up to you (Code First, etc.)
