Remarks

Implement the IOperationBehavior interface to modify, examine, or extend some aspect of operation-wide execution at the application level for Silverlight client applications.

• Use the AddBindingParameters method to pass custom data at runtime to enable bindings to support custom behavior.

• Use the ApplyClientBehavior method to modify, examine, or insert extensions to a client dispatcher in a client application.

• The ApplyDispatchBehavior method is not used in Silverlight 5.

• Use the Validate method to confirm that a OperationDescription meets specific requirements. This can be used to ensure that an operation has a certain configuration setting enabled, supports a particular feature and other requirements.

IOperationBehavior objects can make use of any of these methods, but often only one is important; in such cases, the unused methods can return, performing no action.

Note:
All of the IOperationBehavior methods pass an OperationDescription object as a parameter. This parameter is for examination only; if you modify the OperationDescription object the execution behavior is undefined.

IOperationBehavior objects are typically used to access the various properties of the System.ServiceModel.Dispatcher.DispatchOperation object in a service application and the System.ServiceModel.Dispatcher.ClientOperation object in a client application.

To perform a client customization task, the IOperationBehavior object must be added to the OperationDescription.Behaviors property before calling the ChannelFactory<TChannel>.CreateChannel method or the ICommunicationObject.Open method on ChannelFactory<TChannel>.

Although the operation behavior is designed for easy access to the runtime at the scope of an individual operation, you can access the runtime at a larger scope by accessing the parent runtime object.
