>There is a setting in MTS allowing to specify the unload time after the last instance was released. And guess what... sometimes it works! :) I couldn't find yet the rule that makes it work/fail. :)

It has to do with how MTS interprets idle time for a component.

Regardless, though, that doesn't solve the update problem. With ASP/IIS
there's no way to update a COM object on a busy site without shutting
the site down. Now imagine if you have an app that consists of dozens
of separate COM DLLs... Won't that be fun? <s>
