c# - Can not add reference a COM in COM client?

Question

A COM server is create and I registerd that.

When I am trying to add that COM server in a COM Client, I was not able to add, and following error is comming.

" A reference to 'COMTest' could not be added

The ActiveX type Library 'cuser~DebugCOMTest.tlb' was exported from a .NET assembly and can not added as a reference.

Add a reference to .NET instead "

can anybody tell me What is the mistake. I register the COM in both way, from VS also and also tried with command prompt.

This is a "why on Earth would you do that" message. Project + Add Reference, Browse tab, select the DLL, not the TLB. So you'll use the .NET class(es) directly instead of going through the COM interop twice.
