In questa pagina viene descritto come eseguire in modo programmatico il polling delle
di risorse operation restituite dai metodi in
le API Service Infrastructure che richiedono una quantità di tempo considerevole, come
come

Per eseguire il polling di un'operazione, invoca ripetutamente il metodo
operations.get
con un backoff consigliato di 10 secondi fino al completamento dell'operazione:
