Methods

  Name Description
Public method Abort Causes the ClientBase<TChannel> object to transition immediately from its current state into the closed state. (Inherited from ClientBase<TChannel>.)
Protected method CreateChannel Returns a channel to the service associated with the callback object passed to the constructor. (Overrides ClientBase<TChannel>.CreateChannel().)
Public method Equals(Object) Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected method Finalize Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)
Protected method GetDefaultValueForInitialization<T> Replicates the behavior of the default keyword in C#. (Inherited from ClientBase<TChannel>.)
Public method GetHashCode Serves as a hash function for a particular type. (Inherited from Object.)
Public method GetType Gets the Type of the current instance. (Inherited from Object.)
Protected method InvokeAsync Provides support for implementing the event-based asynchronous pattern. For more information about
this pattern, see Event-based Asynchronous Pattern Overview. (Inherited from ClientBase<TChannel>.)
Protected method MemberwiseClone Creates a shallow copy of the current Object. (Inherited from Object.)
Public method ToString Returns a string that represents the current object. (Inherited from Object.)

Remarks

Extend the DuplexClientBase<TChannel> class to create a Silverlight 5 client object (proxy) that can be used to connect to a duplex service. Duplex communication between a client and service is governed by a message exchange contract in which either endpoint can send messages to the other independently. A callback object is used to enable the service to set up this bidirectional communication.
