I tried the fully qualified name for the class and get the same error - only now it says it can't find the fully qualified name in the Windows assembly. I searched the project and cannot find a duplicate class name.

>Hello, Greg

>From the error you're posting, it looks as if .NET is trying to load your business object from your Windows assembly. Is it possible that you have conflicting namespaces? Maybe two objects with the same name in two different namespaces? At design time, when you type the class name, try using the full namespace and see if that clears the problem.
