WPF XAML StringFormat DateTime: Output in wrong culture?

Question

I\'m having some trouble with the output of a DateTime value. My computer\'s current culture is set to de-AT (Austria).

The following code

string s1 = Da

I Know that this is an aging question but this has always worked for me and sharing knowledge is a good thing. Since my apps always change language on the fly, the FrameworkElement.LanguageProperty.OverrideMetadata only works once and its no good for me, so behold:

this.Language = System.Windows.Markup.XmlLanguage.GetLanguage(ActiveLanguage.CultureInfo.IetfLanguageTag);

where (this) is the MainWindow, actually you have to do it in all rootelements (Windows). There you go simple enough.
