Ok, it works - if you want to call it like this. I can create a MainForm, 
Layout, Buttons etc. and can run my app. But I can't display a "Hello World!" 
because the function "SetCaption" always gives me an error 
(System.MissingMethodException) , even if it isn't overloaded.
But it seems to be the same problem as with overloaded functions, the error is 
the same.
