I am trying to build a web application (ASP.NET) which uses a DLL (created with V. FoxPro 7). The problem is that after running the application the DLL does NOT get released. I can only release it by resetting the IIS service.
I would like to see the DLLHOST.EXE release my COM-DLL as soon as it is no longer in use.

I have tried everything (object = Nothing, Marshal.ReleaseComObject(), etc..). I'm even wondering if this behaviour is normal with .NET, but I still need to know if that's the case. I have consulted in a number of books but nowhere do they mention this kind of problem.

Does anyone know how I can solve this problem? I would be very greatful.
Thanks in advance!
