IOperationBehavior Interface

Implements methods that can be used to extend run-time behavior for an operation in a Silverlight application.

Namespace:  System.ServiceModel.Description
Assembly:  System.ServiceModel (in System.ServiceModel.dll)

public interface IOperationBehavior

The IOperationBehavior type exposes the following members.

  NameDescription
Public methodAddBindingParametersImplement to pass data at runtime to bindings to support custom behavior.
Public methodApplyClientBehaviorImplements a modification or extension of the client across an operation.
Public methodApplyDispatchBehaviorThis method is not used with Silverlight 5 applications.
Public methodValidateImplement to confirm that the operation meets some intended criteria.

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.

NoteNote:

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.

Silverlight
