-            Um die angezeigten Zeichenfolgen zu lokalisieren, kopieren Sie die Werte in
-            die richtig benannten Schlüssel in der Datei der neutralen Ressourcensprache der App (AppResources.resx), und
-            ersetzen Sie den hartcodierten Textwert zwischen den Anführungszeichen des Attributs
-            mit der Bindungsklausel, deren Pfad auf diesen Zeichenfolgennamen verweist.
-
-            Zum Beispiel:
-
-                Text="{Binding Path=LocalizedResources.ApplicationTitle, Source={StaticResource LocalizedStrings}}"
-
-            Diese Bindung verweist auf die Zeichenfolgenressource der Vorlage mit der Bezeichnung "ApplicationTitle".
-
-            Werden auf der Registerkarte mit den Projekteigenschaften unterstützte Sprachen hinzugefügt, wird
-            pro Sprache eine neue resx-Datei erstellt. In dieser können die übersetzten Werte der
-            Zeichenfolgen der Benutzeroberfläche gespeichert werden. Die Bindung in diesen Beispielen führt dazu, dass der Wert der
-            Attribute aus der RESX-Datei entnommen wird, die
-            CurrentUICulture der App zur Laufzeit entspricht.
