The DurableOperationAttribute type exposes the following members.

Constructors
  NameDescription
Public method DurableOperationAttributeInitializes a new instance of the DurableOperationAttribute class.
Top
Properties
  NameDescription
Public property CanCreateInstanceGets 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 property CompletesInstanceGets 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 property TypeIdWhen implemented in a derived class, gets a unique identifier for this Attribute. (Inherited from Attribute.)
Top
Methods
  NameDescription
Public method AddBindingParametersNot implemented in DurableOperationAttribute.
Public method ApplyClientBehaviorNot implemented in DurableOperationAttribute.
Public method ApplyDispatchBehaviorImplements the service-side behavior of the operation.
Public method EqualsInfrastructure. Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute.)
Public method GetHashCodeReturns the hash code for this instance. (Inherited from Attribute.)
Public method GetTypeGets the Type of the current instance. (Inherited from Object.)
Public method IsDefaultAttributeWhen overridden in a derived class, indicates whether the value of this instance is the default value for the derived class. (Inherited from Attribute.)
Public method MatchWhen overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute.)
Public method ToStringReturns a string that represents the current object. (Inherited from Object.)
Public method ValidateNot implemented in DurableOperationAttribute.

Explicit Interface Implementations
  NameDescription
Explicit interface implemetation Private method _AttributeGetIDsOfNamesMaps a set of names to a corresponding set of dispatch identifiers. (Inherited from Attribute.)
Explicit interface implemetation Private method _AttributeGetTypeInfoRetrieves the type information for an object, which can be used to get the type information for an interface. (Inherited from Attribute.)
Explicit interface implemetation Private method _AttributeGetTypeInfoCountRetrieves the number of type information interfaces that an object provides (either 0 or 1). (Inherited from Attribute.)
Explicit interface implemetation Private method _AttributeInvokeProvides access to properties and methods exposed by an object. (Inherited from Attribute.)

Remarks

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.
