It looks like, your WCF service and client (WcfTestClient) both are in one solution. WcfTestClient is provided by Microsoft visual studio just for your unit testing. But in actual project, generally WCF service is used in a distributed environment. That means your WCF service would be running in some system and the client (who uses that service) would be on the another system. In that case, your client will access WCF service interfaces through a client proxy class. This proxy of the service can be created either by svcutil command OR adding a service reference. Now suppose, a new interface is added on your service side, then client can access that newly added interface only by updating its proxy. In order to update the proxy, either you may need to run again svcutil command OR updating the service reference (if you have added a service reference already) As per MSDN: The WCF client proxy can be generated manually by using the Service Model Metadata Utility Tool (SvcUtil.exe) for more information see, ServiceModel Metadata Utility Tool (Svcutil.exe) . The WCF client proxy can also be generated within Visual Studio using the Add Service Reference feature refer to link, how to consume service in client using service reference: http://msdn.microsoft.com/en-us/library/bb655893%28v=vs.90%29.aspx and another link where client is using svcutil command: http://msdn.microsoft.com/en-us/library/ms734691.aspx Hope this will help you to understand the WCF basics...

No, there is no way. Your client can only know those operation contracts (interfaces) which it finds in the proxy class. So to get the new proxy either go by updating reference or get by svcutil command.

I have an idea.... If you create proxy class for your service by yourself using 'svcutil' command, then it's easy. Create a proxy using svcutil. On success, that will have 4 methods. Then remove 2 interfaces (which you don't need) and use this partial proxy class for one client and do similarly for other. But if you add a service reference, then we need to think how to supress two interfaces for one client...
