Service implementation exhibit:
class PassGuideService: IPassGuideService
{
public void PassGuideOp1(string value) {}
public void PassGuideOp2(string value) { }
}
Contract exhibit:
[ServiceContract(SessionMode s SessionMode Required)]
public interface IPassGuideService
{
[OperationContract(IsOneWay = true, IsInitiating = true)]
void PassGuideOp1(string value);
[OperationContract(IsOneWay = true, IsInitiating = false)]

void PassGuideOp2(string value);
}
