How to Get the Windows Phone App version from WMAppManifest file ?

The WMAppManifest file is just an XML file and hence we can use the XDocument class to retreive this element from the file.

private void Button_Click_1(object sender, RoutedEventArgs e)
{
  string appVersionNumber = XDocument.Load("WMAppManifest.xml")
         .Root.Element("App").Attribute("Version").Value;
  MessageBox.Show(appVersionNumber);
}
