如何创建可用于c ++和c＃的dll？

Question

I need to develop a library that can be used for both c++ application and also by c# universal store app.
My research so far:

• Developing in c++ wont help because c# uwp will only accept PCL.

• Developing as PCL in c# cannot be added to c++ applications.

(I am not sure about the second case. Correct me if I am wrong.)
Is there way to developing a common library ? or I have to develop it in those two platforms separately.

Answer 1

如果创建C ++库，则可以从C ++中使用它（显然），并且可以为此C ++库创建一个C ++ / CX包装器，该包装器可以在C＃中使用。

Answer 2

You can also use COM objects. You can then import the library in Visual Studio and then they will be available as regular objects.

From the CPP point of view to create COM objects the "atl" is probably the best approach.

COM objects can be hard to implement but they can be imported in many languages and compilers.
