  NameDescription
Public methodSupported by Silverlight for Windows PhoneDisposeRestores the original OperationContext to the active context and recycles the OperationContextScope object.
Public methodSupported by Silverlight for Windows PhoneEquals(Object)Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected methodSupported by Silverlight for Windows PhoneFinalizeAllows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)

Use the OperationContextScope class to create a scope for a specific OperationContext object or a scope for a new OperationContext object using a specified IContextChannel object. An OperationContextScope can be used in a Windows Communication Foundation (WCF) service as well as in a Silverlight 5 client application.

After the OperationContextScope object has established the current operation context, you can use the OperationContext to:

  • Access and modify incoming and outgoing message headers and other properties.

  • Access the runtime, including dispatchers, the host, channel, and extensions.

  • Access other types of contexts, such as security, instance, and request contexts.

  • Access the channel associated with the OperationContext object or (if the channel implements System.ServiceModel.Channels.ISession) the associated channel's session identifier.

When an OperationContextScope is created, the current OperationContext is stored and the new OperationContext becomes the one returned by the Current property. When the OperationContextScope is disposed of, the original OperationContext is restored.

The following example shows how to use the OperationContextScope to create a new context in a client application to add a custom header to the outgoing message.
