Use “real” CultureInfo.CurrentCulture in WPF Binding, not CultureInfo from IetfLanguageTag

Question

In my case:

I have a TextBlock Binding to a property of type DateTime. I want it to be displayed as the Regional settings of the User says.

Answer 1

How about changing the lanaguge in the code behind?

this.Language = XmlLanguage.GetLanguage(Thread.CurrentThread.CurrentCulture.Name);
