Which means either (1) the system keeps some sort of a list of outstanding COM objects, and weak references to the owning object (would seem rather silly), or (2) you have to release COM servers manually, period. Since I don't have access to a .NET SDK here, I can't really test what's right. Adam Nathan's book might shed some light, too.
