I am using a config file to register a few singleton service types when my application launches. I would like to be able to make these unavailable at specific times in the application, not only when it shuts down entirely. I'm wondering what is the best means of doing so? ChannelServices.UnregisterChannel could in theory blow out other registered types besides the ones that I need to strictly control availability to, so I'm looking for a best approach since there is no UnregisterWellKnownServiceType() at this point. Thanks, Kris
