Hi,
you simply cannot unload an assembly from an appdomain once you have loaded
it. If you need to unload assemblies, load them in different AppDomains.
Kind regards,
Henning

I was able to get around the file locking issue by reading the DLL
into memory and loading the assembly from there. However, it appears
IIS never releases the assembly because its memory usage continues to
climb with every call to the web service.
I feel like I'm missing something simple here. =)
