I don't get how is that possible ... you say your class C calls method
on B thus ... "myB.MethodOfA"


So MethodOfA *must* be in (public) interface of B in order to be
callable like that... maybe a concrete example could clear this up?


Anyways, if inheritance gives you trouble you can always go and do
a "replace inheritance with delegation".
