Hinweise

Ein Objekt muss die ISponsor Schnittstelle implementieren, wenn es eine Leaseverlängerung für ein bestimmtes Objekt anfordern muss. Ein Objekt, das die ISponsor Schnittstelle implementiert, kann ein Sponsor werden, indem es sich beim Lease-Manager registriert. Die ISponsor Schnittstelle wird vom Dienst für die Lebensdauer verwendet, um den Sponsor zurückzurufen.
