How do I mix C# and C++ code in a single assembly?

If your C++ code is not compiled with /clr:safe (i.e. it is compiled with /clr or /clr:pure), do the following:

1) compile your C++ code into .obj files

2) compile your C# code into a .netmodule, using /AddModule to reference the C++ .obj files

3) link the C# netmodule directly with the C++ object files using the C++ linker to create a mixed language assembly

If your C++ code is compiled with /clr:safe, build your C++ code as a .netmodule. You can use it just like you would use a .netmodule from any other language.

  How about the opposite -- is there an "easy" (relatively) way to take a mixed mode assembly and decompile it to the il + native code chunk?

  Does this not work in .NET 1.1?

  Do you have a simple sample showing the cs and cpp code?
