I am working on WP7 app, When i was trying to navigate on same page as i was working on...my app was crashing. i was keep getting this error message "No Fragment support right now". So i googled it and find out the solution which stops crashing app.

private void hyperlinkButtonHome_Click(object sender, RoutedEventArgs e)
{
NavigateTo("/HomePage.xaml");
}

// prevents crash when trying to navigate to current page
public static void NavigateTo(string url)
{
var frame = App.Current.RootVisual as PhoneApplicationFrame;
if ((frame == null) || (url == frame.CurrentSource.ToString()))
return;
frame.Navigate(new Uri(url, UriKind.Relative));
}

Not sure it's right solution but it stops crashing app.
