Quando viene chiamato per la prima volta, il metodo corrente crea un WaitHandle oggetto e lo restituisce.When called for the first time, the current method creates a WaitHandle object and returns it. Nelle chiamate successive, CreateWaitHandle restituisce un riferimento a un nuovo handle di attesa.On subsequent calls, CreateWaitHandle returns a reference to a new wait handle.

Utilizzare questo metodo se si implementano i metodi asincroni e si richiede un modo per bloccare in EndRead o EndWrite fino al completamento dell'operazione asincrona.Use this method if you implement the asynchronous methods and require a way of blocking in EndRead or EndWrite until the asynchronous operation is complete.
