Use the DuplexClientBase<TChannel> class to create a channel to a service that specifies a callback object. The DuplexClientBase<TChannel> object wraps a System.ServiceModel::DuplexChannelFactory<TChannel> object, which provides the connectivity for the WCF object. You can use either type to connect to a duplex service. For more information about duplex services, see Duplex Services.

Special note for Managed C++ users deriving from this class:

  • Put your cleanup code in (On)(Begin)Close (and/or OnAbort), not in a destructor.

  • Avoid destructors: they cause the compiler to auto-generate IDisposable

  • Avoid non-reference members: they can cause the compiler to auto-generate IDisposable

  • Avoid finalizers; but if you include one, you should suppress the build warning and call SuppressFinalize(Object^) and the finalizer itself from (On)(Begin)Close (and/or OnAbort) in order to emulate what would have been the auto-generated IDisposable behavior.

The following example shows the use in the client of a duplex WCF client type, the SampleDuplexHelloClient, to pass a new System.ServiceModel::InstanceContext object with the callback object to listen for callbacks.
