Hinweise

Wenn die Laufzeit eine Assembly lädt, wird die KeyPair Eigenschaft nicht festgelegt. Der Getter für die Eigenschaft ist nur nützlich, wenn der Benutzer die Eigenschaft vor der Verwendung des AssemblyName Objekts zum Erstellen einer dynamischen Assembly festgelegt hat und anschließend das Schlüsselpaar abrufen möchte.
