How do you make .Net components that could be used by COM
The tool Regasm.exe can create a COM typelib and creates the necessary entries in the registry (the CLSID and Typelib ). If only a typelib is required, you can use tlbexp.exe. A com callable wrapper (CCW) will be created when a COM client (VB, VBS, JS, C++ etc.) creates an instance of a (managed) class.
