Please post Beta2 questions to the VS2005 Beta forum
http://forums.microsoft.com/msdn/ , these forums are meant to support
customers for the Visual Studio 2005 Beta 2 release and are replacing the
private whidbey NG's.

That said , the sample you are refering to works for me, I guess you run a
modified version.
