Steps for calling COM DLL API in my C# code

I have got a native DLL that I wanted to use via COM in my .NET/C# project. I am a little confused on the steps to follow in order to use it in my C# project. Here is what I understand, please correct me wherever I am wrong.

  1. Register COM DLL on the machine using regsvr32.
  2. Somehow get the interop DLL(RCW) from that native DLL. Not sure how to do that?
  3. Add reference to interop DLL in .NET/C# project
  4. Starting referencing calls from COM dll.

If it is a COM component (it has to be designed and compiled as such), you can add a COM reference using the Add Reference dialog; you will then have wrapper classes created for you.

If you are simply using a native DLL (not a COM component), you need to use DllImport to call native methods.
