Why do I have to reference the WCF Service Application within the WPF Application when there's a reference within the Class Library and the WPF never directly uses the WCF?

Assume WCF refer to the namespaces of either System.ServiceModel or System.ServiceModel.Web
A pure WPF application does not neither use nor reference to any classes in WCF, which means you should not have to.
But, if the UI (Presentation) layer refers to one of the objects from a class library, and that object (public of course) somehow depends on WCF (using one of WCF objects as arguments, return types in its public interface - methods, properties, constructors, etc, attribute declaration like [ServiceContract], or extending a class of WCF), you must have System.ServiceModel (and/or SystemServiceModel.Web) in WCF layer as well, even there is nowhere in the presentation layer directly invoke those methods that would return a WCF object, or passing WCF objects as arguments.
The design of the object in the class library being used in your WPF has introduced unneeded dependency, the WCF, to WPF layer. Time to refactor your code.
