[Mono-list] .NET/C++ Interop

I do not know of any Managed C++ compilers other than VS.NET. I would really 
like to see a minimal Managed C++ compiler to help with the integration of C# 
and C++.

The main problems in using C++ with C# is that object allocation must be done 
through C/C++ and that function names in C++ are "mangled". 

It is possible to call C++ from Mono. There are two approaches. One is to 
create a C "glue" library so that C# calls the C-glue and the C-glue calls 
C++. The C library must be build using the same compiler that built the C++ 
library to ensure compatible object allocation and name mangling. It is also 
possible to call from C# to C++ directly for normal method calls, but C# 
extern declarations must include the mangled names (possibly using the 
EntryPoint modified of DllImport). Object allocation still needs some C glue,
