CompositeDuplexBindingElement Class
Represents the binding element that is used when the client must expose an endpoint for the service to send messages back to the client.
System.ServiceModel.Channels.BindingElement
System.ServiceModel.Channels.CompositeDuplexBindingElement
Namespace: System.ServiceModel.Channels
Assembly: System.ServiceModel (in System.ServiceModel.dll)
The CompositeDuplexBindingElement type exposes the following members.
| Name | Description | |
|---|---|---|
 | CompositeDuplexBindingElement | Initializes a new instance of the CompositeDuplexBindingElement class. |
| Name | Description | |
|---|---|---|
| BuildChannelFactory<TChannel> | Returns a channel factory that can create a composite duplex channel. (Overrides BindingElement.BuildChannelFactory<TChannel>(BindingContext).) |
| BuildChannelListener<TChannel> | Returns a channel listener that can accept a composite duplex channel. (Overrides BindingElement.BuildChannelListener<TChannel>(BindingContext).) |
| CanBuildChannelFactory<TChannel> | 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. (Overrides BindingElement.CanBuildChannelFactory<TChannel>(BindingContext).) |
| CanBuildChannelListener<TChannel> | 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. (Overrides BindingElement.CanBuildChannelListener<TChannel>(BindingContext).) |
| Clone | Returns a deep clone of the current binding element. (Overrides BindingElement.Clone().) |
| Equals(Object) | Determines whether the specified object is equal to the current object. (Inherited from Object.) |
| GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
| GetProperty<T> | Returns a typed object requested from the appropriate layer in one of the channel stacks. (Overrides BindingElement.GetProperty<T>(BindingContext).) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
| Name | Description | |
|---|---|---|
| IPolicyExportExtension.ExportPolicy | Exports custom policy assertions about bindings that represent the presence of composite duplex in the binding. |
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.
Windows 8, Windows Server 2012, Windows 7, Windows Vista SP2, Windows Server 2008 (Server Core Role not supported), Windows Server 2008 R2 (Server Core Role supported with SP1 or later; Itanium not supported)
The .NET Framework does not support all versions of every platform. For a list of the supported versions, see .NET Framework System Requirements.
