Using the launcher to start Internet Explorer from Code in Windows Phone 7.
Currently in the Mix 2010 pre-release of the Windows Phone 7 SDK the external launchers are still very much under development. But you can already use them to launch the built-in Internet Explorer from your application.
All you need to do is to reference the external library “Microsoft.Phone.Tasks” and use the WebBrowserTask class as follows:
public partial class MainPage : PhoneApplicationPage
private void hyperlinkbuttonExternal_Click(object sender, RoutedEventArgs e)
WebBrowserTask task = new WebBrowserTask();
task.URL = textboxUrl.Text;
The super simple sample code shows the difference between the XAML WebBrowser control and the WebBrowserTask.
