Recently in writing the Warensoft3d game engine, and expected to release the beta version early next year, the underlying engine was written using DirectX and Mono, the upper logic was written in C #, so a lot of C # and C + + intermodulation code

The compiler is the prototype of the empty class generation function and the time when the function is createdIn C + + when creating an empty class, C + + creates 4 functions for the class by default: The default constructor, destructor, copy
