I can't find the bug # right now, but I'm assuming you are talking about
Release being called on the finalizer thread instead of the correct
creating/apartment of the COM object? I understand how it
can especially cause problems with UI controls requiring access on only the
UI thread. This is a very difficult bug to fix, due to the fact that if the
apartment of the COM object does not pump messages the application will
deadlock. Even more complicated is what message loop to use in the non-Win32
I'm willing to take a look at solutions to this issue, but I can't think of
any easy ones. There are multiple blog posts on how tricky it was for MS to
avoid deadlock in their runtime, including things like randomly pumping
Ivo, Joe is right to mention this. I've made all my COM objects free
threaded to avoid this issue. If your COM objects rely on STA behavior,
you're going to run into troubles.
