  1. CsWin32

    A source generator to add a user-defined set of Win32 P/Invoke methods and supporting types to a C# project.

    Would something like CsWin32 help?

  3. cppcomponents

    Allows you to write binary components in C++11 that can be used across different compilers and standard libraries

    You may find https://github.com/jbandela/cppcomponents useful. A portable C++11 library allowing COM components to be created from a C++ library. Note the portable, you can 100% make COM components on POSIX as well.

  4. CppSharp

    Tools and libraries to glue C/C++ APIs to high-level languages

    I would give CppSharp a crack first. It generates a .net wrapper using pinvoke.

NOTE: The number of mentions on this list indicates mentions on common posts plus user suggested alternatives. Hence, a higher number means a more popular project.
