This works (the socket is created and I can receive data). The problem is
when I exit my application I get a Debug Assertion from sockcore.cpp in line

Sockcore.cpp line 234 is a blank line (in VS 2005) in an unrelated
function. So it would be a lot of help if you report details about the
function and actual code that asserted on your particular setup.

The code you posted says that you are using CAsyncSocket directly
instead of deriving a class from it. If you don't derive a class you
can't override CAsyncSocket::OnClose!
