How to change default language of Web Browser control

Question

I have a trouble with a WPF application. The application uses a web browser to display a certain page (Internet Explorer). The problem is the inner browser of the application shows the page always with a language configuration in English, regardless of the configuration of the browser. When Im testing the application, It takes the language features of the browser; but before it compiles it changes and uses English language.

Is there a way to change the default language? How can I set it to use the language defined in the browser?

I don't understand fine your problem, but WPF is known that ignores the "culture". I solve with this trick:

public partial class App : Application
{
    protected override void OnStartup(StartupEventArgs e)
    {
        FrameworkElement.LanguageProperty.OverrideMetadata(typeof(FrameworkElement), new FrameworkPropertyMetadata(XmlLanguage.GetLanguage(CultureInfo.CurrentCulture.IetfLanguageTag)));
    }
