COM interop from IAS Extension DLL

Hey guys,

Has anyone here actually written an IAS extension DLL where you call a COM
component written in C#? I have opened a PSS case with Microsoft and for
weeks we have been trying to figure this out to no avail. I can call a COM
component written in C++ just fine, but the system hangs when I try to call
a COM component written in C#.

The current assumption is that the interop may be an issue. But that doesn't
make a lot of sense since the extension DLL is nothing more than a Win32
DLL. I have a test MFC application that calls it fine. Its only in IAS that
it appears to die. Basically when CoCreateInstance() is called in
RadiusExtensionProcess() the system freezes in what seems like a deadlock,
and requires a reboot.

Anyone have any ideas?? Has anyone actually DONE this? Newsgroup achives
have people saying to do it this way... but there has been no follow up to
say it worked or not.
