CompositeDuplexBindingElement Class

Definition

Namespace:

System.ServiceModel.Channels

Assembly:

System.ServiceModel.dll

Represents the binding element that is used when the client must expose an endpoint for the service to send messages back to the client.

C#

public sealed class CompositeDuplexBindingElement : System.ServiceModel.Channels.BindingElement, System.ServiceModel.Description.IPolicyExportExtension

Inheritance

Object

BindingElement

CompositeDuplexBindingElement

Implements

IPolicyExportExtension

Remarks

This is commonly used with transports, such as HTTP, that do not allow duplex communications natively. TCP, by contrast, does allow duplex communications natively and so does not require the use of this binding element for the service to send messages back to a client.

The client must expose an address at which the service can contact it to establish a connection from the service to the client. This client address is provided by the ClientBaseAddress property. Note that Windows Communication Foundation (WCF) auto-generates a ClientBaseAddress if one is not explicitly set by the user.

Constructors

CompositeDuplexBindingElement()

Initializes a new instance of the CompositeDuplexBindingElement class.

Properties

ClientBaseAddress

Gets or sets the base address for the client.

Methods

BuildChannelFactory<TChannel>(BindingContext)	Returns a channel factory that can create a composite duplex channel.
BuildChannelListener<TChannel>(BindingContext)	Returns a channel listener that can accept a composite duplex channel.
CanBuildChannelFactory<TChannel>(BindingContext)	Returns a value that indicates whether the binding can build the channel factory that produces a specific type of channel that satisfies the context requirements.
CanBuildChannelListener<TChannel>(BindingContext)	Returns a value that indicates whether the binding can build the channel listener that accepts a specific type of channel that satisfies the context requirements.
Clone()	Returns a deep clone of the current binding element.
Equals(Object)	Determines whether the specified object is equal to the current object. (Inherited from Object)
GetHashCode()	Serves as the default hash function. (Inherited from Object)
GetProperty<T>(BindingContext)	Returns a typed object requested from the appropriate layer in one of the channel stacks.
GetType()	Gets the Type of the current instance. (Inherited from Object)
MemberwiseClone()	Creates a shallow copy of the current Object. (Inherited from Object)
ToString()	Returns a string that represents the current object. (Inherited from Object)

Explicit Interface Implementations

IPolicyExportExtension.ExportPolicy(MetadataExporter, PolicyConversionContext)

Exports custom policy assertions about bindings that represent the presence of composite duplex in the binding.
