Therefore I'm using the Entity Framework 4 Designer. A created a new "ADO.Net Entity Data model" file, with the extension .edmx. I created two Entities: I want to add a 1 to nc relation between Product -> Group.

I was able to double click on the line (association line) in the designer. Fill in the properties there and I got it working. I also had to close VS and re-open it to get some of the errors reported to go away... Can't say this is the correct answer - just fumbling

C:\Users\Andrew\Documents\Visual Studio 2012\Projects\WEB Projects _3\Demo\Demo\SmurfEntities.edmx 35 9 Demo As for this issue, it seems the issue is related the model will not validate until all objects in the model are mapped to the database.
