Hi Arun, By using Name property in the attribute "OperationContract" we can handle the operator overloading in the services. As you know operator overloading means the same name with different parameter types or different in number of parameters Overloaded operations (methods) are not supported in WSDL based operation. So, the alernative is to provide different name to the operations exposed by the WCF service. Check the following: Here all the method names are same. But while exposing the service we are changing the operation names using OperationContract so the service still be able to get exposed with no issues. [ServiceContract] interface IService { [OperationContract(Name = "SumOfInt")] int SumOfTwoNumbers(int a,int b); [OperationContract(Name = "SumOfDouble")] double SumOfTwoNumbers(double a,double b); [OperationContract(Name = "SumOfThreeDouble")] double SumOfTwoNumbers(double a,double b,double c); } Let me know if you have any questions.
