I have two entities, each from a different database and therefore different edmx files.

I have two entities, each from a different database and therefore different edmx files. There is, however, an infered relationship between them.

Foo has many Bars for example.

What’s the easiest way to do this join in the EntityFramework, with fewest database calls?

Thanks.

    You can do this by adding cross-model navigation properties. This requires manually editing the EDMX. There is an example, including LINQ to Entities, here.
