DurableOperationAttribute Class

Note: This API is now obsolete.

Specifies the local execution behavior of a durable service method.

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


[ObsoleteAttribute("The WF3 types are deprecated.  Instead, please use the new WF4 types from System.Activities.*")]
public sealed class DurableOperationAttribute : Attribute, IOperationBehavior


Initializes a new instance of the DurableOperationAttribute class.


Gets or sets a value that indicates whether a new service instance can be created if an activation message is received on this operation. The dispatcher considers messages without an attached instance ID to be activation messages.


Gets or sets a value that indicates whether the service instance will be unloaded from memory and deleted from persistence once the operation has finished executing.


When implemented in a derived class, gets a unique identifier for this Attribute.(Inherited from Attribute.)

System_CAPS_pubmethodAddBindingParameters(OperationDescription, BindingParameterCollection)

Not implemented in DurableOperationAttribute.

System_CAPS_pubmethodApplyClientBehavior(OperationDescription, ClientOperation)

Not implemented in DurableOperationAttribute.

System_CAPS_pubmethodApplyDispatchBehavior(OperationDescription, DispatchOperation)

Implements the service-side behavior of the operation.


This API supports the product infrastructure and is not intended to be used directly from your code. Returns a value that indicates whether this instance is equal to a specified object.(Inherited from Attribute.)


Returns the hash code for this instance.(Inherited from Attribute.)


Gets the Type of the current instance.(Inherited from Object.)


When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class.(Inherited from Attribute.)


When overridden in a derived class, returns a value that indicates whether this instance equals a specified object.(Inherited from Attribute.)


Returns a string that represents the current object.(Inherited from Object.)


Not implemented in DurableOperationAttribute.

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute.GetIDsOfNames(Guid, IntPtr, UInt32, UInt32, IntPtr)

Maps a set of names to a corresponding set of dispatch identifiers.(Inherited from Attribute.)

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute.GetTypeInfo(UInt32, UInt32, IntPtr)

Retrieves the type information for an object, which can be used to get the type information for an interface.(Inherited from Attribute.)


Retrieves the number of type information interfaces that an object provides (either 0 or 1).(Inherited from Attribute.)

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute.Invoke(UInt32, Guid, UInt32, Int16, IntPtr, IntPtr, IntPtr, IntPtr)

Provides access to properties and methods exposed by an object.(Inherited from Attribute.)

Durable service state information will be persisted when the operation has successfully been invoked. You cannot persist state information during the middle of operation execution as you can with workflow services.
