WPF StringFormat={0:C} showing as dollars

Question

Why does this line of code

<TextBlock Text="{Binding Net, StringFormat=c}"/>

Output the result as $xx.xx when all my regional settings are set to UK. I expect it to output it as £xx.xx. Any ideas? I have tried different variations of the stringformat including StringFormat={}{0:C} but still get the same result.

Thanks for looking.

I'm not sure if this has been fixed in .NET 4, but WPF has never picked up the current culture when rendering things like currency or dates. It's something I consider a massive oversight, but thankfully is easily corrected.

In your App class:

protected override void OnStartup(StartupEventArgs e)
{
    FrameworkElement.LanguageProperty.OverrideMetadata(
        typeof(FrameworkElement),
        new FrameworkPropertyMetadata(
            XmlLanguage.GetLanguage(
            CultureInfo.CurrentCulture.IetfLanguageTag)));
    base.OnStartup(e);
 }
