Hi Arjun, Physically you can have the overloading while defining the operation contracts which exposes as web methods to the cusumers. But it should be with the different name. For example, [OperationContract] void ShowNames(string name) [OperationContract] void ShowNames(string name1, string name2) Here i have overloaded two web methods. But in the proxy client you can't have two methods with the same name. It should be renamed through the Name property in the operationcontract. [OperationContract] void ShowNames(string name) [OperationContract[Name="ShowTwoNames"] void ShowNames(string name1, string name2) For more info: http://www.c-sharpcorner.com/uploadfile/dhananjaycoder/operation-overloading-in-wcf/ http://jeffbarnes.net/blog/post/2006/09/21/Overloading-Methods-in-WCF.aspx
