Look at this issue i have created in Codeplex.

Same class name Entity
Re: Same class name Entity
We have reproduced the following error with your test project in our environment:
This is a limitation of Entity Framework.Failure: System.NotSupportedException : The type 'SziCom.Degas.Entity.Model.Sistema.Usuario' and the type 'SziCom.Degas.Entity.Model.Degnet.Usuario' both have the same simple name of 'Usuario' and so cannot be used in the same model. All types in a given model must have unique simple names. Use 'NotMappedAttribute' or call Ignore in the Code First fluent API to explicitly exclude a property or type from the model.
