IContextChannel Interface
[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]
Defines the interface for the context control of a channel.
Assembly: System.ServiceModel (in System.ServiceModel.dll)
The IContextChannel type exposes the following members.
| Name | Description | |
|---|---|---|
 | AllowOutputBatching | Gets or sets a value that instructs Windows Phone to store a set of messages before giving the messages to the transport. |
| Extensions | Gets a collection of extension objects for this extensible object. (Inherited from IExtensibleObject<T>.) |
| InputSession | Gets the input session for the channel. |
| LocalAddress | Gets the local endpoint for the channel. |
| OperationTimeout | Gets or sets the time period within which an operation must complete or an exception is thrown. |
| OutputSession | Gets the output session associated with the channel, if any. |
| RemoteAddress | Gets the remote address associated with the channel. |
| SessionId | Returns an identifier for the current session, if any. |
| State | Gets the current state of the communication-oriented object. (Inherited from ICommunicationObject.) |
| Name | Description | |
|---|---|---|
 | Abort | Causes a communication object to transition immediately from its current state into the closed state. (Inherited from ICommunicationObject.) |
| BeginClose(AsyncCallback, Object) | Begins an asynchronous operation to close a communication object. (Inherited from ICommunicationObject.) |
| BeginClose(TimeSpan, AsyncCallback, Object) | Begins an asynchronous operation to close a communication object with a specified time-out. (Inherited from ICommunicationObject.) |
| BeginOpen(AsyncCallback, Object) | Begins an asynchronous operation to open a communication object. (Inherited from ICommunicationObject.) |
| BeginOpen(TimeSpan, AsyncCallback, Object) | Begins an asynchronous operation to open a communication object within a specified interval of time. (Inherited from ICommunicationObject.) |
| Close() | Causes a communication object to transition from its current state into the closed state. (Inherited from ICommunicationObject.) |
| Close(TimeSpan) | Causes a communication object to transition from its current state into the closed state. (Inherited from ICommunicationObject.) |
| EndClose | Completes an asynchronous operation to close a communication object. (Inherited from ICommunicationObject.) |
| EndOpen | Completes an asynchronous operation to open a communication object. (Inherited from ICommunicationObject.) |
| GetProperty<T> | Returns a typed object requested, if present, from the appropriate layer in the channel stack. (Inherited from IChannel.) |
| Open() | Causes a communication object to transition from the created state into the opened state. (Inherited from ICommunicationObject.) |
| Open(TimeSpan) | Causes a communication object to transition from the created state into the opened state within a specified interval of time. (Inherited from ICommunicationObject.) |
| Name | Description | |
|---|---|---|
 | Closed | Occurs when the communication object completes its transition from the closing state into the closed state. (Inherited from ICommunicationObject.) |
| Closing | Occurs when the communication object first enters the closing state. (Inherited from ICommunicationObject.) |
| Faulted | Occurs when the communication object first enters the faulted state. (Inherited from ICommunicationObject.) |
| Opened | Occurs when the communication object completes its transition from the opening state into the opened state. (Inherited from ICommunicationObject.) |
| Opening | Occurs when the communication object first enters the opening state. (Inherited from ICommunicationObject.) |
The IContextChannel defines the controls for the context of a channel. This includes the SessionId, InputSession, OutputSession, and AllowOutputBatching for the channel, and the LocalAddress and RemoteAddress for the endpoints that are participating in the session.
Capabilities
If you use this API in your app, you must specify the following capabilities in the app manifest. Otherwise, your app might not work correctly or it might exit unexpectedly.
