You wrote..."You can have a library project include custom config files and those files can be copied to the executable location of another application (it's a little sticky, but not too big a deal). You just have to use OpenMappedExeConfiguration to get to any information in those files. You'd then have to do some custom coding when you instantiate your WCF proxies (instantiate a Binding and pass that to the proxy). I'm late to the party here, but I can provide more details if you're interested"
Can you provide these details please. It would be really helpful. thanks.
