Is it possible to run unmanaged C ++, usually from a managed C ++ / CLI project?

I am in the process of packaging a clean unmanaged VC ++ 9 project in C ++ / CLI to use it directly from a .NET application. I know how to write wrappers , and that unmanaged code can be executed with .NET , but that I cannot completely wrap my head:

  • Unmanaged lib is a very complex C ++ library and uses many built-in and other functions, so I can not compile them into a managed DLL /clr. I need to compile this into a separate DLL using a regular VC ++ compiler.

  • How to export characters from this unmanaged code so that it can be used from a C ++ / CLI project? I will mark every class I need, how extern? Is it easy or is there some difficulty?

  • How do I access exported characters from a C ++ / CLI project? I just include the unmanaged source code header files and does C ++ compose the personal code from the unmanaged DLL? Or do I need to manually write a separate set of "extern" classes in a new header file that points to classes in the DLL?

  • When my C ++ / CLI project creates unmanaged classes, will the unmanaged code work fine in a normal VC9 runtime or force it to run in .NET? causing more compatibility issues?

  • A C ++ project creates many instances and has its own custom-made garbage collector written in simple C ++, this is a DirectX sound visualization tool and manages many DirectX objects. Will all of this work fine, or will such Win32 features be affected in any way?

You can start with a regular native C ++ project (imported, say, from Visual Studio 6.0 from more than ten years ago), and when you create it today, it will reference the current version of the VC runtime.

It also seems that C ++ interaction technology might come in handy: http://msdn.microsoft.com/en-us/library/2x8kf7zx(v=vs.80).aspx
