I need to implement a Service with CallBack Contract and setting
TransportMode in binding configuration set to Streamed.

When i try to instance ServiceHost it's throw an
System.InvalidOperationException with Message like 'Contract Require
Duplex but on Binding Configuration is not Supported or is not been
Configured'

How Can I use Streamed TransportMode and Duplex Communication Service?

Xml Configuration:

<configuration>
     <system.serviceModel>
         <behaviors>
             <serviceBehaviors>
                 <behavior name="NewBehavior">
                     <serviceMetadata />
                 </behavior>
             </serviceBehaviors>
         </behaviors>
         <bindings>
             <netTcpBinding>
                 <binding name="NewBinding0" transferMode="Streamed" />
             </netTcpBinding>
         </bindings>
         <services>
             <service behaviorConfiguration="NewBehavior"
name="CallBackService.CallBackService">
                 <endpoint address="CallBackService"
binding="netTcpBinding" bindingConfiguration="NewBinding0"
                     contract="CallBackService.ICallBackService" />
                 <endpoint address="CallBackService/mex"
binding="mexTcpBinding"
                     bindingConfiguration="" contract="IMetadataExchange" />
                 <host>
                     <baseAddresses>
                         <add baseAddress="net.tcp://acquleobook" />
                     </baseAddresses>
                 </host>
             </service>
         </services>
     </system.serviceModel>
</configuration>

P.S.

I'm using for callback One-Way OperationContract due to fix WinForms
Main Thread Deadlock.

Thanks
