The perfect solution would probably be making the constructor of the internal class visible only to the outter class. I'm not aware of a technique that would enable that. Or in c++ there's the friend keyword, which hasn't been adopted into C#(as far as I now)
Wouldn't making the inner constructor private solved the problem though?
