You could take a look at SWIG: https://www.swig.org/Doc3.0/CSharp.html

That depends entirely on what you mean by "interface them". Are you trying to use a C++ library in a C# app? A C# library in a C++ app? Or whatever else. You're going to have to go into far more detail to get a reasonable answer.

yes, I must use a c++ library in c# app

If you're not in a hurry, maybe transfer a file between them.

For a non-NET C++ Executable (EXE or DLL) you use the DllImportAttribute Class (System.Runtime.InteropServices) | Microsoft Learn[^]

Solution 3

Now that you've completely reverse the question, and still left out a lot of detail, about the best you're going to get is this: use c# dll in C++ - Google Search[^]

The quality of the answers you get is directly dictated by the quality of the question you ask.

Solution 4

A c# class can expose itself as a COM Server:
C# code [^]

and, If all other methods do not work, you can always use the socket API for interoperability.
