The best solution in WPF i have found is to use DispatcherTimer:

    private readonly DispatcherTimer _dispatcherTimer;

    public MyClass()
    {
        InitializeComponent();

        WBrowser.Navigate(loginUri);

        _dispatcherTimer = new DispatcherTimer();
        _dispatcherTimer.Tick += dispatcherTimer_Tick;
        _dispatcherTimer.Interval = new TimeSpan(0, 0, 0, 0, 200);
        _dispatcherTimer.Start();
    }

    private void dispatcherTimer_Tick(object sender, EventArgs e)
    {
        if (WBrowser.Source == null)
        {
            _dispatcherTimer.Stop();
            Close();
        }
    }
    protected override void OnClosed(EventArgs e)
    {
        base.OnClosed(e);

        if (_dispatcherTimer.IsEnabled)
        {
            _dispatcherTimer.Stop();
        }
    }

    private void WBrowser_OnNavigated(object sender, System.Windows.Navigation.NavigationEventArgs e)
    {
        if(!_dispatcherTimer.IsEnabled)
        {
            _dispatcherTimer.Start();
        }
    }
