How can i globally set the Culture in a WPF Application?

Question

I would like to set the Culture of a WPF application to a specific one based on user preferences.

I can do this for the current thread via Thread.CurrentThrea

Answer 1

ok so this is what I use in order to make sure all of my app is in a en-US culture.

CultureInfo.DefaultThreadCurrentCulture = new CultureInfo("en-US");
CultureInfo.DefaultThreadCurrentUICulture = new CultureInfo("en-US");
XmlLanaguage lang = XmlLanguage.GetLanguage(CultureInfo.CurrentCulture.IetfLanguageTag);
FrameworkElement.LanguageProperty.OverrideMetadata(typeof(FrameworkElement), new FrameworkPropertyMetadata(lang));
FrameworkContentElement.LanguageProperty.OverrideMetadata(typeof(System.Windows.Documents.TextElement), new FrameworkPropertyMetadata(lang));

in order to make a single thread in a culture you can make

Thread.CurrentThread.CurrentCulture = new CultureInfo("EN-US");
Thread.CurrentThread.CurrentUICulture = new CultureInfo("EN-US");
