Well, we built the solution using Visual Studio 2005. It looks like you're using Visual Studio C# Express Edition.
I'm not sure if you can mix and match, but I'll find out. We may need to put together a Visual Studio C# Express Solution.

Actually, I just installed Visual Studio C# Express Edition, and I see the same error you're seeing. So, I'll work on getting a solution together for the VS Express Edition users early next week.
