ChannelDispatcherBase Class

Abstract base class for the channel dispatcher that accepts channels and associates them with a service.

Namespace:  System.ServiceModel.Dispatcher
Assembly:  System.ServiceModel (in System.ServiceModel.dll)

public abstract class ChannelDispatcherBase extends CommunicationObject

This is used by developers who want to keep the Windows Communication Foundation (WCF) programming model but replace the system-provided runtime. Such applications will pull messages out of channels and handle them directly with user-defined dispatchers. To use ChannelDispatcherBase , create a class derived from it, extend ServiceHost and override InitializeRuntime, adding instances of your class derived from ChannelDispatcherBase to ChannelDispatchers.

The IChannelListener and the ServiceHost, associated with the ChannelDispatcherBase object are available for inspection or modification through the Listener and Host respectively.

ServiceHost calls the Attach(ServiceHostBase) or Detach(ServiceHostBase) methods when adding or removing a ChannelDispatcherBase item from its ChannelDispatchers collection.

ServiceHost calls the CloseInput during shutdown before closing InstanceContexts. Windows Communication Foundation (WCF) uses this call to close datagram channels and wait for all messages to get to an InstanceContext.

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
