I´m Using VS 2012 Upd1 ... Project on 4.5 .NET version

Another problem using CodeFirst with EF 5.0 :

A null was returned after calling the 'get_ProviderFactory' method on a store provider instance of type '#=qf0iMQzhvbP6M0$32V3mHgOt1NyP9C$utBNdXCP9dPByUnWxAI6KkoWRChMmAjV5NV$FRZw9O3fbl6fM$1mgyOg=='. The store provider might not be functioning correctly.
