I have a Visual Studio 2010 solution with 2 projects. One is a Silverlight client, the other a web site to which I added a domain service. It works fine when debugging in Cassini, but when I publish to IIS I get nothing returned from my entity query.
I'm not even sure where to start as this is my first attempt at doing this.
This was a very stupid, newbie issue. I used SQL Server Profiler to watch the queries come in and realized the account being used to authenticate against SQL Server was the server's computer account. I secured the Domain Service's methods and allowed the computer account access tot he DB.
