I was working on one of my assemblies yesterday which we have in our GAC and
is used by a number of our web applications/sites on our intranet.
Something strange started happening though. I would compile the program,
then do the following in order given:

gacutil /u myAssembly
gacutil /i myAssembly.dll
net stop iisadmin
net start w3svc

Yet IIS and the web applications conitnued to use the old code, no matter
how i played with these steps and the order of them. The only way i could
get IIS to use the new code was to open a windows explorer windows to
C:\WINNT\Assembly, locate my assembly, right click it and go to properties.
Once i did this, IIS would use the new code. This sounds totally bizarre,
but i ran the process over and over and over and over, first trying without
going to the file, then going to the file, and it was 100% consistent.

Can anyone explain this behaviour to me??
TIA - Aaron.
