Q: 

Composite Foreign keys with MS Entity Framework

Hi,

I'm trying to create an entity model that involves two tables related. The issue that i'm getting into is that they are related using a composite foreign key.

When the model is created, I can't find the relation between both entities.

I tryied to create it by hand, but got to the next error:

Error 111:The properties referenced by the principal role NEXO_TIPO_ANUNCIO have to be exactly the same as the key from EntityType ModeloNexo.NEXO_TIPO_ANUNCIO that is referenced by the Principal Role...

Anyone knows if it is an issue or a feature?

thanks in advance, Libo
