Error:

The type 'System.Data.Entity.DbContext' is defined in an assembly that is not referenced. You must add a reference to assembly 'EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.

As you can see my Entity Framework is complaining at the reference, tried to solve it but got nowhere. Has someone experienced this problem before? I'm basically trying to do this: http://www.asp.net/web-api/overview/getting-started-with-aspnet-web-api/tutorial-your-first-web-api

What did you tried to do to resolve? Added the dll manually? installed the nuget package on the project? – dariogriffo Dec 23 '14 at 16:49

You need to install EF first from NuGet before it will work with your project. – Corey Adler Dec 23 '14 at 16:49

Try restore packages if you downloaded the files from web. – radu florescu Dec 23 '14 at 16:50

Go to your solution and follow this steps(provided that you use a downloaded zip from the page you specified):

Right click on sln node and Enable Nuget package restore, then rebuild you sln.
If not already installed try open the Manage Nuget Package and check EF is installed.
Would not recommend loading dll by hand, but you can try adding it.
