One reason that is the rule in VFP is that if you use the class designer for your classes then it's really hard to change the baseclass of a class.

In c# it's much easier to change the baseclass of a class than it was in VFP so I don't think subclassing if you don't need to is that beneficial.

>>I would subclass everything that you intend to use. Don't use the Framework classes directly on your forms, period. Today, you might not think you need to extend such-and-such a class ... but tomorrow you may realize that you needed to. Just go ahead and subclass all that you use now and you won't be kicking yourself in the butt later on.
