There are two ways as far I know: Using Interface Refactor your service contracts to exposes two endpoints the interface of which is only relevant to the client that is consuming it: [ServiceContract] public interface IService1 { [OperationContract] void OperationOne(); } [ServiceContract] public interface IService2 { [OperationContract] void OperationTwo(); } // Develop a class which implements IService1 IService2 for first client public class MyServcie1: IService1 IService2 { //Implementation here... } // Develop a class which implements IService1 for second client public class MyServcie2: IService1 { //Implementation here... } Using Explicitly Develop Multiple service Go through below link: http://dotnetmentors.com/multiple-wcf-services-in-one-solution-with-multiple-endpoints-and-hosting.aspx
