A service proxy or simply proxy in WCF enables application(s) to interact with WCF Service by sending and receiving messages. It’s basically a class that encapsulates service details i.e. service path, service implementation technology, platform and communication protocol etc. It contains all the methods of service contract (signature only, not the implementation). So, when the application interact the service through proxy, it gives the impression that it’s communicating a local object.
We can create proxy for a service by using Visual Studio or SvcUtil.exe.
