EF5 Code First, Error in RIA Service

Apr 7, 2013 at 3:10 AM
I am getting the following error in my DbDomainService when I add the .Include to my entity in the Get query:
Invalid Include specification for member 'Player.Answers'. Non-projection includes can only be specified on members with the AssociationAttribute applied.
My GetPlayers() method looks like this:
public IQueryable<Player> GetPlayers()
            return this.DbContext.Players.Include("Answers");
What do I need to do to get this completed and working? I finally got everything else working as is in your Demo app and following the Step-by-Step. This is my final hurdle.

Thank you,
Cindy K.

Incidentally, I have tried adding the [Include] attribute to the PlayerMetatdata class for the Answers collection, and that doesn't solve the problem, either.
