Dawn of Light

Managed Extensions for C++ is least likely to operate under Mono. Mono does not support mixed mode assemblies (that is, assemblies containing both managed and unmanaged code, which Managed C++ can produce). You need a fully-managed assembly to run under Mono, and getting the Visual C++ .NET compiler to generate such an executable can be difficult. You need to use only the .NET-framework assemblies, not the C libraries (you can't use printf(3) for example.), and you need to use the linker options /nodefaultlib /entry:main mscoree.lib in addition to the /clr compiler flag. You can still use certain compiler intrinsic functions (such as memcpy(3)) and the STL. You should also see Converting Managed Extensions for C++ Projects from Mixed Mode to Pure Intermediate Language at MSDN. Finally, you can use PEVERIFY.EXE from the .NET SDK to determine if the assembly is fully managed.
