IGeneric Derived1 .GetName return Derived1 string IGeneric Derived2 .GetName return Derived2 If I use the non generic DoubleDown..
What is allowed in Visual Basic that's prohibited in C# (or vice versa)? http://stackoverflow.com/questions/966457/what-is-allowed-in-visual-basic-thats-prohibited-in-c-sharp-or-vice-versa sub Foo other as Base other.m_x 2 end sub end class class Derived2 inherits Base end class Because a Derived1 is a base it can.. something that is not a Derived1 it could for example be a Derived2 and so it does not allow access to m_x . share improve this..
