Updating hosted service

I'm designing a windows service to run a self-hosted scenario of services
that are loaded from GAC. I've created a "drop" folder, in which to drop the
..dll of the service I want to host. My service watches this folder and when a
file has been dropped in, I install it into the GAC and load the ServiceHost.
Now, my trouble is that when I'm "updating" an existing hosted service, it
does not reflect the updated code that I've installed to the GAC, even though
I close the ServiceHost and create a new service host from the GAC. It seems
to cache to original service somewhere until I actually restart my Windows
service. Is there a way to dynamically change the hosted service without
having to restart the entire windows service, which will be hosting a variety
of other hosted services which don't need to be restarted?

You are not using a fully qualified name when loading the dll?
When loading the new dll using reflection, use the LoadFile over LoadFrom
method as this gives you the correct assembly (presented a full path).

Curiousity: why install it into the GAC? It would work just as well without
all the hassle of interacting with the GAC.
