The evidence I have gathered so far suggests that the best way to a

Mono has recently made some pretty big strides with C++ interoperability in CXXI (pronounced sexy).

From this posting, the short story is that the new CXXI technology allows C#/.NET developers to:

• Easily consume existing C++ classes from C# or any other .NET language
• Instantiate C++ objects from C#
• Invoke C++ methods in C++ classes from C# code
• Invoke C++ inline methods from C# code (provided your library is compiled with -fkeep-inline-functions or that you provide a surrogate library)
• Subclass C++ classes from C#
• Override C++ methods with C# methods
• Expose instances of C++ classes or mixed C++/C# classes to both C# code and C++ as if they were native code.

CXXI is the result of two summers of work from Google's Summer of Code towards improving the interoperability of Mono with the C++ language.
