Thetype exposes the following members.
|SaveStateInOperationTransaction||Gets or sets a value that indicates whether the service instance state is persisted to the PersistenceProvider using the same transaction under which the operation is run.|
|TypeId||When implemented in a derived class, gets a unique identifier for this Attribute. (Inherited from Attribute.)|
|UnknownExceptionAction||Gets or sets the UnknownExceptionAction enumeration value associated with the durable service.|
|AddBindingParameters||Not implemented in .|
|ApplyDispatchBehavior||Customizes the service runtime to support durable service behavior properties, such as specifying a PersistenceProvider for the service.|
|Equals||Infrastructure. Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute.)|
|GetHashCode||Returns the hash code for this instance. (Inherited from Attribute.)|
|GetType||Gets the Type of the current instance. (Inherited from Object.)|
|IsDefaultAttribute||When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class. (Inherited from Attribute.)|
|Match||When overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute.)|
|ToString||Returns a string that represents the current object. (Inherited from Object.)|
|Validate||Verifies that all durable operations on the service are set up correctly.|
|_AttributeGetIDsOfNames||Maps a set of names to a corresponding set of dispatch identifiers. (Inherited from Attribute.)|
|_AttributeGetTypeInfo||Retrieves the type information for an object, which can be used to get the type information for an interface. (Inherited from Attribute.)|
|_AttributeGetTypeInfoCount||Retrieves the number of type information interfaces that an object provides (either 0 or 1). (Inherited from Attribute.)|
|_AttributeInvoke||Provides access to properties and methods exposed by an object. (Inherited from Attribute.)|
The following items are checked as part of the validation logic for durable services:
The ConcurrencyMode value must not be set to Multiple.
The InstanceContextMode value must be PerSession.
There must be one sessionful endpoint configured for the service.
If the contract disallows sessions, then CanCreateInstance must be set to true for all operations.
If SaveStateInOperationTransaction is set to true, then all operations on the service must either be marked with OperationBehaviorAttributeTransactionScopeRequired set to true or marked with TransactionFlowOptionMandatory. Additionally, ConcurrencyMode must be set to Single.
