Linda,

>I am using C# and I was dragging from the Solution Explorer. When I tried it using the class view, it worked as described in the Jump Start instructions.

This sounds like the behavior you get when you right-click a project and select View Class Diagram...it adds all the classes in your project to the class diagram.

I recommend creating a new class diagram by using the Add | New Item dialog and see if you have the same behavior.

Best Regards,
