Public Property PersistableIdle As Func(Of WorkflowApplicationIdleEventArgs, PersistableIdleAction)

The delegate that is invoked when the current workflow instance is idle and can be persisted.

The following example handles the PersistableIdle handler and instructs the runtime to persist and unload the workflow.

wfApp.PersistableIdle = delegate(WorkflowApplicationIdleEventArgs e)
{
    // Instruct the runtime to persist and unload the workflow
    return PersistableIdleAction.Unload;
};

When a workflow becomes idle and can be persisted, both Idle and PersistableIdle are invoked, in that order. The PersistableIdle handler returns one of the PersistableIdleAction enumeration values of None, Persist, or Unload.
