want to open Link in external browser of WP7

问题:

The architecture is like:
On click of a button an HTML page opens which contains a link in it. On clicking the links I want to open it in external (default) browser of WP7 such that the application closes and link opens externally. How can I implement this?
Added this control in xaml file:

<phone:WebBrowser Name="browser" Margin="0,78,0,0" />

On button click:

   private void Information_Loaded(Object sender,RoutedEventArgs e)
   {
       Assembly assembly = Assembly.GetExecutingAssembly();

       using (Stream stream = assembly.GetManifestResourceStream("index_en.html"))
       {
           using (StreamReader reader = new StreamReader(stream))
           {
               string html = reader.ReadToEnd();

               browser.NavigateToString(html);                   
           }
       }

Now index_en.html has a link which is to be opened in external browser.

You can use the WebBrowserTask to launch the browser.

I've found that you need to escape the URL you pass to it though :(

Normally, you would do so using Target property on <a> tag. But, in WP7 (at least in Emulator), this does not work.

What you could do is intercept using Navigating event something like following:

void WebBrowser1_Navigating(object sender, NavigatingEventArgs e)
{
    if (IsSupposedToOpenInPhoneBrowser(e.Uri))
    {
        e.Cancel = true;
        WebBrowserTask task = new WebBrowserTask();
        task.URL = e.Uri.ToString();
        task.Show();
    }
}

You can use something like that

private void Button_Click_1(object sender, RoutedEventArgs e)
{
    WebBrowserTask webBrowserTask = new WebBrowserTask();
    webBrowserTask.Uri = new Uri("http://www.someUrl.com");
    webBrowserTask.Show(); 
}
