備註

任何知道已註冊已知物件之 URI 的用戶端都可以藉由向註冊慣 ChannelServices用的通道來取得物件的 Proxy，並藉由呼叫 new 或 Activator.GetObject 方法來啟用物件。若要使用 new啟用已知的物件，您必須先使用 RegisterWellKnownClientType 方法在用戶端上註冊已知的物件類型。 RegisterWellKnownClientType呼叫方法會提供遠端基礎結構遠程物件的位置，以允許new關鍵詞加以建立。如果另一方面，您可以使用 Activator.GetObject 方法來啟動已知的物件，您必須提供物件的URL做為自變數，因此不需要在用戶端端進行先前的註冊。

當呼叫抵達伺服器時，.NET Framework 會從訊息擷取 URI、檢查遠端數據表以找出符合 URI 之對象的參考，然後視需要具現化物件，並將方法呼叫轉送至物件。如果對象註冊為 SingleCall，則會在方法呼叫完成之後終結。系統會為每個呼叫的方法建立物件的新實例。和 new 之間的Activator.GetObject唯一差異在於前者可讓您將URL指定為參數，而後者則會從組態取得URL。

遠端物件本身不會由註冊程式具現化。只有在用戶端嘗試在物件上呼叫方法，或從客戶端啟動物件時，才會發生這種情況。
