    Acknowledgement in WCF duplex callback?

    I had design a simple WCF duplex callback application. After the client
    subscribe to host service, it will receive a callback when there is a event
    fired.
    If i need an acknowledgement from the client to indicate it success retrieve
    and if fail receive then i will re-send the data to the client. Any
    possibility to do it in the duplex callback ? if yes, please provide some
    sample coding, thanks!
