What exactly does the VS project option "Register for COM interop" actually do? Because when I build my library with this option enabled I'm able to view it in the COM tab inside the VS Add Reference screen. But if I build without this and then run regasm manually (already including /codebase parameter) I can't see it in the COM Dll list, neither inside VS Add Reference screen or VB6 References screen. So, I'm wondering -- what does VS2010 do that I'm not doing?
I already searched for this topic inside StackOverflow, and found this link, which didn't solve my problem: What does "Register for COM Interop" actually do?
Regasm shows me: Types registered successfully So, I don't have any extra info.
