Does what?

The additional space consumption is significant if you have eg. a class
that would otherwise be the size of a pointer (and you need to instantiate
millions of them). If you had forced virtual functions, it would double in
size.

How would you implement a GUI library without using any kind of inheritance?

But C# shouldn't have the same problems as Java. Mostly.
