A is Form control and B is UserControl

i'd like to make inherit both userControl Form

You can't do this. .NET only allows for single-inheritance, meaning,
you can only derive from a single base class.

What you are trying to do doesn't make sense anyways. Why not just
place all of your UI on a UserControl and then have an instance of that user
control in a Form?

As Nicholas said, you can only inherit from a single class, but you can inherit multiple interfaces. Not sure what you expect to happen if you inherit from both a Form and a UserControl, but look into interfaces, they may give you what you need.
