You need to set the FrameworkElement.Language property. The easiest way to do that for the whole application is to override the property metadata in the App class static constructor:

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

If you only want to set the culture for a specific control, you can bind its Language property to a property of your datacontext:

<TextBlock Text="{Binding Something}" Language="{Binding TheLanguage}" />
