Classe CompositeActivity che contiene l'attività radice clonata per il flusso di lavoro.
Esempio
Nell'esempio riportato di seguito viene illustrata l’aggiunta di attività alla proprietà TransientWorkflow. Questo esempio è tratto dall'esempio SDK Ordering State Machine. Per altre informazioni, vedere Ordering State Machine Sample.For more information, see Ordering State Machine Sample.
// Create a new instance of the WorkflowChanges class for managing
