You create a Windows Communication Foundation service by using Microsoft .NET Framework 3.5.
You write the following code segment.

[ServiceContract]
public interface IMathservice
{
[OperationContract]
int AddNumbers(int a, int b);
double AddNumbers(double a, double b);
}

You have not deployed the IMathservice service.
You need to expose the AddNumbers (double a, double b) operation to the IMathservice service contract.
Which code segment should you use?

A.
[OperationContract]
int AddNumbers(int a, int b);
[OperationContract]
double AddNumbers(double a, double b);

B.
[OperationContract(Name="AddInt")]
int AddNumbers(int a, int b);
[OperationContract(Name="AddDouble")]
double AddNumbers(double a, double b);

C.
[OperationContract(Action="IMathservice/AddInt")]
int AddNumbers(int a, int b);
[OperationContract(Action="IMathService/AddDouble")]
double AddNumbers(double a, double b);

D.
[OperationContract(Action="AddInt/*")]
int AddNumbers(int a, int b);
[OperationContract(Action="AddDouble/*")]
double AddNumbers(double a, double b);
