I want to build a WCF data service which should be used for CRUD operations on a database backend. In order to identify the related record of the object in the database I have to know it's primary key. I use surrogate keys in my database schema.

Hi, I'm having a couple of issues which may be related, or may not. I noticed that when I use Add Service Reference in Visual Studio to add a reference to my data service, the reference.cs it generates does not compile. It complains about a missing namespace.
