>I want to try to create a couple of forms to be my base class forms that will be used (inherited from) by the application (or maybe future applications). For example, I can create a maintenance base form and then inherit from it for various table maintenance forms. I think that I can only do it in code (not visually); correct me if I am wrong. But my question on where to create these base UI forms. Do I create a separate solution for these base UI classes and then reference it into my application solution? Or copy the base class files into my application solution?

AFAIK, it should be a separate project and then you include the dll reference into your other project where you want to use them.
