References for DBContext, DBSet<> in Entity Framework

Question

I am trying to use ADO.Net Codefirst feature of latest Entity Framework 4.0. As part of that I have installed Entity Framework CTP 4 from Microsft and using Scott's tutorial to create the model first. Inside the tutorial DBContext and DBSet<> is specified. Could some tell what is the reference to be used in order to access this class.

I have used the following references however nothing happens for DBContext and DBSet<>

• System.Data.Entity
• System.Data.Entity.Design

You can use the Library Package Manager if you have it (it installs automatically with MVC 3.0).

From within your project in Visual Studio 2010, go to

Tools > Library Package Manager > Package Manager Console 

From within your project in Visual Studio 2013, go to

Tools > NuGet Package Manager > Package Manager Console 

In the console, after the PM> prompt, type

install-package entityframework 

This will install the package and add the EntityFramework reference to your project.

Use CTP5 instead it is newer version with some changes in API. You have to add reference to EntityFramework.dll which is installed in CTP directory - default is: c:\Program Files\Microsoft ADO.NET Entity Framework Feature CTP5\Binaries\EntityFramework.dll for 32bit system. On 64bit system it will be placed in Program Files (x86).
