    public sealed partial class MainPage : Page
    {
        public string access_token = null;
        public MainPage()
        {
            this.InitializeComponent();
            auth.Navigate(new Uri("https://oauth.vk.com/authorize?client_id=2720784&scope=2625424&redirect_uri=http://oauth.vk.com/blank.html&display=touch&response_type=token"));
        }
        void auth_Navigated(object sender, System.Windows.Navigation.NavigationEventArgs e)
        {
            GetAccessTokenFromUri(auth.Source.AbsoluteUri);
        }
        public void GetAccessTokenFromUri(string uri)
        {
            char[] excessChars = { '=', '&' };
            string[] response = uri.Split(excessChars);

            foreach (string s in response)
            {
                if (s.Length == 63)
                    access_token = s;
             
            }
            if (access_token != null)
            {
                string destination = string.Format("/Menu.xaml?access_token={0}", access_token);
                NavigationService.Navigate(new Uri(destination, UriKind.Relative));
            }

        }
      
        protected override void OnNavigatedTo(NavigationEventArgs e)
        {
        }
    }
}

Error on line:

void auth_Navigated(object sender, System.Windows.Navigation.NavigationEventArgs e)

Well, to begin with, you didn't declare the object "auth".

If my reply answers your question, please mark this post as answered.

If I ask for code, please provide something that I can drop directly into a project and run (including XAML), or an actual application project. I'm trying to help a lot of people, so I don't have time to figure out weird snippets with undefined objects and unknown namespaces.
