Writing a DLL in C/C++ for .Net interoperability

Question

In my C# application, I would like to write a part of the code in C. I plan to write a DLL witch would be interoperable with .Net. How can I do that?

Answer 1

In a nutshell:

(1) Create a new C++/CLI library project.

(2) Write your code. For classes that need to be accessible from your C# project, make sure to create them as CLR classes:

public ref class R {/*...*/};       // CLR class
public value class V {/*...*/};     // CLR struct
public interface class I {/*...*/}; // CLR interface

(3) Compile the project and add a reference to it in your C# project.
