I've created a WCF service based on an Entity Framework model. When I consume the service from a console app, a WinForm app, and a WPF app, everything just works. I can see the entites and can add/delete/etc. However, when I try to consume the same WCF service from a web app, I get errors stating that the entities are not recognized. Looks like the edm is not being included in the service refernce in this case. Suggestions? Thx.
