Reference to assembly error

I've implemented the RoleProvider class, there I created Domain class object which is in another assembly, my assembly has a reference to that one.

Error 3 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'. D:\Visual Studio 2013\Group 06\G06_Store\Store.Facade\StoreRoleProvider.cs 17 24 Store.Facade

How can I fix this error?

I've also found that if you have say a Console App as the main project, with a unit test project running on the side, this error will come up if you don't have a reference to EntityFramework on the unit test project you will get this error as well.

2) Restart Visual Studio

3) Reinstalling Entity Framework to all required projects
