Managed C++ IS good :-)

After my ill-advised rant about managed C++ I learned something interesting. Managed C++ is a great bridge between a C# model and unmanaged C++ code, especially if your method signatures are kind of complex. Managed C++ does a better (quicker) job of marshaling between it's module and the unmanaged C++ module than PINVOKE does.

Also, you don't have to learn those fancy PInvoke attributes and duplicate structures in C# and C++.

Therefore, managed C++ is the most elegant solution to bridge between C# and unmanaged C++.
