title: What does “Register for COM Interop” actually do? Q2
body: <p>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 (<strong>already including /codebase parameter</strong>) 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?</p>
  
  <p>I already searched for this topic inside StackOverflow, and found this link, which didn't solve my problem:
  <a href="https://stackoverflow.com/questions/3534600/what-does-register-for-com-interop-actually-do">What does &quot;Register for COM Interop&quot; actually do?</a></p>
  
  <p>Regasm shows me: Types registered successfully
  So, I don't have any extra info.</p>
