How can I test a COM interface implemented in .NET?

Question

I have written a COM interface in C#. I then tried to write a simple application that references it so that I can test the COM interface, however Visual Studio does not allow COM interfaces to be referenced if they have been written in C#.

Is there any way to get around this? If not, which language is likely to be the easiest for me to accomplish my task?

Answer 1

I would suggest the Excel VBA editor for this.

Open Excel, hit Alt + F11 to invoke the VBA editor.

Create a new module, go to Tools -> References, find your COM object in the list, and check the box.

You should then be able to create an object, and test your interface is working.
