OK, this is a new issue. My guess is that somehow your business object project has been set as the main startup project rather than your Web Forms project (the MM .NET Wizard sets your Web Forms project as the main startup project).

You can easily see which is the startup project because it is displayed in bold in the Solution Explorer. If this is the case, simply right-click your Web Forms project and select "Set as Startup Project" from the shortcut menu, and then rebuild!
