Something new on this. I just discovered the ReleaseComObject method. I have it in my aspx page like this:

scmal.StateCentralClass scMal = new scmal.StateCentralClass();
while (System.Runtime.InteropServices.Marshal.ReleaseComObject( scMal ) > 0) {}

in order to reduce the reference count to zero. I am going to experiment with it in my page and see if it makes my VFP objects "go away" any faster than just doing

scmal.StateCentralClass scMal = new scmal.StateCentralClass();
scMal = null;

Maybe Ed Ruah or Rick Strahl will smell this thread and lend their $.02 as well....
