When i remove from table foreign key my data model (edmx file) is not generate correctly(model is update from database, from editor i add in primary key this propery StoreGeneratedPattern="Identity). After build solution get error:
The associated metadata type for type 'MyPrj.Web.SomeClass' contains the following unknown properties or fields...
I think that some automatic generated class are cached but i can't remove or recreate its.
I spend a lot of hours trying to resolve this problem but without success :(
