Hinweise

Wenn eine Oid Eigenschaft auf einen bekannten Wert festgelegt ist, wird der Wert der anderen Oid Eigenschaft automatisch auf einen entsprechenden Wert aktualisiert. Wenn die Value Eigenschaft beispielsweise auf "1.3.6.1.5.5.7.3.4" festgelegt ist, wird die FriendlyName Eigenschaft automatisch auf "Sichere E-Mail" festgelegt.

In .NET 5 und höheren Versionen ist diese Eigenschaft nur init, was bedeutet, dass ihr Wert nach dem Festlegen nicht mehr geändert werden kann.
