How we can achieve Operation Overloading while exposing WCF Services?

Answer

By default, WSDL doesn’t support operation overloading. Overloading behavior can be achieved by using “Name” property of OperationContract attribute.

 [ServiceContract]
 interface IMyCalculator
 {
        [OperationContract(Name = “SumInt”)]
        int Sum(int arg1,int arg2);
        [OperationContract(Name = “SumDouble”)]
        double Sum(double arg1,double arg2);
  }

When the proxy will be generated for these operations, it will have 2 methods with different names i.e. SumInt and SumDouble.
