First of all, why would you entangle WPF and WCF in this question? These things are unrelated, don't mix all things together. Ever heard of
separation of concerns? Please see:

Besides, even though you can host a WCF service in a windowed or other interactive application (again, it does not matter if it is WPF or not), this is not an adequate form of application user as a service (but it's a good idea to have such interactive version of the same application, as debugging is a whole lot easier). The adequate form of application hosting any kind of services is the Windows Service:

Now, how to use WCF? I would advise to use WCF
self-hosted in the service application. Please see:

To understand how can it look along with the clients, please see this article on WCF hosting and consuming:

This should be enough to get started. For some good code sample, you can also perform the CodeProject article search. But not mix it with WPF. :-)
