Remarks
A workflow instance can be unloaded from memory by an explicit call to Unload, or implicitly by the workflow run-time engine according to its own semantics. For example, the workflow run-time engine unloads a workflow instance if the instance becomes idle and the runtime has a WorkflowPersistenceService added for which UnloadOnIdle is true.
The workflow run-time engine raises the WorkflowUnloaded event after the state of the workflow instance has been successfully persisted but before the instance is invalidated in memory. Therefore, a WorkflowPersisted event precedes the WorkflowUnloaded event.
For the WorkflowUnloaded event, the sender contains the WorkflowRuntime and WorkflowEventArgs contains the WorkflowInstance associated with the event.
