WCF Service Method Overloading

-
You all may have found this one out even earlier, but I found this out just a few days before. A WCF Service doe not allow normal method overloading , which is supported by .NET. It throws InvalidOPerationException.

As for the reasons to why this happens is becasue WSDL is not a object orinted language and does not support these features of OOP. However overloading can be performed in WCF service in a roundabout way.

[ServiceContract]
interface ICalculator
{
[OperationContract(Name="AddTwoIntegers")]
int Add(int a,int b)

[OperationContract(Name="AddThreeIntegers")]
int Add(int a,int b,int c)
}

The Name property in the OperationContract attribute enables the WSDL to make the difference between to same named methods here.
