The type 'System.Data.Entity.DbContext' is defined in an assembly that is not referenced. You must add a reference to assembly 'EntityFramework 2

.net entity-framework

Question

I've got one solution - the one project is class library with .edmx data model The other is asp.net web forms project.

when i start the solution I get the following exception:

The type 'System.Data.Entity.DbContext' is defined in an assembly that is not referenced. You must add a reference to assembly 'EntityFramework, Version=5.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.

and when I see the references in my asp.net project I see the reference to my class and I can't see reference to entity framework. But the problem is that entity framework is installed both in my class library and web project

Assembly 'EntityFramModel' uses EntityFramework 5.0 which has a higher version thhan the referenced assembly

Since you use your edmx in your webproject you need to reference the same Entity Framework dll in the web project as you have in your library. Your error suggests, that you use a different version of the entity dll.
