Using C++ unmanaged class in C# class library

Question

How can I import a class from a C++ unmanaged project and use it in a C# class library? The solutions I have seen worked in execute projects. Are there any step by step guides?

Answer 1

A native C++ class can't be directly consumed from C#/.NET code.

You can wrap the native C++ class using a tiny C++/CLI interop layer , and then use that from C#.

Or you could build a COM wrapper around the native C++ class, and consume the COM component from C#.

Another option would be to build a DLL with a pure C interface , wrapping the native C++ class, and then consume that C-interface DLL from C# using P/Invoke.
