DurableOperationAttribute Class

Specifies the local execution behavior of a durable service method.


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

public sealed class DurableOperationAttribute : Attribute, 

The DurableOperationAttribute type exposes the following members.

Public methodDurableOperationAttributeInitializes a new instance of the DurableOperationAttribute class.

Public propertyCanCreateInstanceGets 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.
Public propertyCompletesInstanceGets 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.
Public propertyTypeIdWhen implemented in a derived class, gets a unique identifier for this Attribute. (Inherited from Attribute.)

Public methodAddBindingParametersNot implemented in DurableOperationAttribute.
Public methodApplyClientBehaviorNot implemented in DurableOperationAttribute.
Public methodApplyDispatchBehaviorImplements the service-side behavior of the operation.
Public methodEqualsInfrastructure. Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetHashCodeReturns the hash code for this instance. (Inherited from Attribute.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Public methodIsDefaultAttributeWhen overridden in a derived class, indicates whether the value of this instance is the default value for the derived class. (Inherited from Attribute.)
Public methodMatchWhen overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)
Public methodValidateNot implemented in DurableOperationAttribute.

Explicit interface implemetationPrivate method_Attribute.GetIDsOfNamesMaps a set of names to a corresponding set of dispatch identifiers. (Inherited from Attribute.)
Explicit interface implemetationPrivate method_Attribute.GetTypeInfoRetrieves the type information for an object, which can be used to get the type information for an interface. (Inherited from Attribute.)
Explicit interface implemetationPrivate method_Attribute.GetTypeInfoCountRetrieves the number of type information interfaces that an object provides (either 0 or 1). (Inherited from Attribute.)
Explicit interface implemetationPrivate method_Attribute.InvokeProvides 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.
