Provides classes related to persistence.
|PersistenceIOParticipant||A derived vclass of the PersistenceParticipant class with methods that perform input and output operations in addition to the persisting and loading of workflow instances through the persistence process.|
|PersistenceParticipant||This class allows both WorkflowApplication and WorkflowServiceHost to participate in persistence process. A persistence participant derives from the PersistenceParticipant class or the PersistenceIOParticipant class (derived class of the PersistenceParticipant class), implements abstract methods, and then add an instance of the class as a workflow instance extension. The WorkflowApplication and WorkflowServiceHost look for such extensions when persisting an instance and invoke appropriate methods at appropriate times.|
