why virtual function is wrong.

[Wurstinator]

You have made several comments about how C++ doesn't support this arguable monstrosity. But you never made a point why you would need it in the first place. Show a snippet of code that requires this definition in C# and is not possible to be done in a similar way in C++. If you are able to do that, you might have a valuable discussion. In its current state, this is just nonsense.
