Thanks for your comment.

But sorry because I think I haven't understood you completely.

You say I can't define a class without empty constructor? That's not 
true. When you create an empty Console application in Visual Studio, 
there is a "class Program" that contains an static method but does not 
have any constructor.

If you were trying to say that all classes, at the compiler level, 
contain an empty constructor, then ok; but what I want to do is to force 
a class to have a public empty constructor, and, if it doesn't have it, 
have the compiler to warn me because of the semantic requisite.

Is there a way to achieve this?
