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?

1) Uninstall Entity Framework from All projects

2) Restart Visual Studio

3) Reinstalling Entity Framework to all required projects

and it started working

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.
