Deriving from a Form class in .NET

Question

Theoretically you can derive from a Form, but is it something you should not do? I intuitively think so, but I've never heard of any rule like this.

I mean some conrete class that already derives from Form. For example, if I've got class MyForm : Form, the question is: can I derive from MyForm?

Answer 1

You should derive from Form when creating a new Windows Form. When creating a new form in Visual Studio, the source files you get already derive from Form.
