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

The problem that is avoiding using "this.Language = XmlLanguage.GetLanguage(Thread.CurrentThread.CurrentCulture.Name);" is not really a common one. I don't know any user here in france that will change the date format to US or Japan one, just because at least no user is knowing that such a change is possible (and dont know how to do it)... So of course the "language=" is not perfect, but in many many years of WPF and Silverlight practice I never see a problem of this kind with any user... So I still use the "Langage=" trick, it is simple and cover 100% of real needs. Of course others solutions seem to be better, but there is no need for (and I saw a few implementations that are far from perfect compare to "language=" solution).
