Read this article. You should set default language for all framework elements:

public partial class App : Application
{
    static App()
    {
        FrameworkElement.LanguageProperty.OverrideMetadata(
            typeof(FrameworkElement),
            new FrameworkPropertyMetadata(
                XmlLanguage.GetLanguage(CultureInfo.CurrentCulture.IetfLanguageTag)));
    }
}
