Thanks for help.
But the example CalculatorDuplex is named Duplex. But it is not work on duplex mode.
Because there all the service are set as
[OperationContract(IsOneWay=true)]
So how it work as duplex mode?

"IsOneWay=true" is not related to Duplex. It just says that the Operation doesn't return a response. You can remove it and return e.g. an integer or something like that if you like.
Take a look at the "ICalculatorDuplexCallback" usage this is how the Server -> Client calls are made
