How to set and change the culture in WPF

Question

I have a .NET 4.0 WPF application where the user can change the language (culture) I simply let the user select a language, create a corresponding CultureInfo and set:

I never found a way to do exactly what I asked for in the question. In my case I ended up solving it by having all my usercontrols inherit from a superclass that contained this:

/// 

///   Contains shared logic for all XAML-based Views in the application. 
///   Views that extend this type will have localization built-in.
/// 
public abstract class ViewUserControl : UserControl
{
    /// 

    ///   Initializes a new instance of the ViewUserControl class.
    /// 
    protected ViewUserControl()
    {
        // This is very important! We make sure that all views that inherit 
        // from this type will have localization built-in. 
        // Notice that the following line must run before InitializeComponent() on 
        // the view. Since the supertype's constructor is executed before the type's 
        // own constructor (which call InitializeComponent()) this is as it 
        // should be for classes extending this
        this.Language = XmlLanguage.GetLanguage(CultureInfo.CurrentCulture.IetfLanguageTag);
    }
}

When the user changes the language I then create new instances of any usercontrols that are currently running.

This solved my problem. However, I would still like a way to do this "automatically" (i.e. without having to keep track of any instantiated objects).
