Question

I m getting an error in WP 7.1 like below

InvalidOperationException
“Navigation is not allowed when the task is not in the foreground”

In the following line of code

NavigationService.Navigate(new Uri("/PhotoPreview.xaml", UriKind.Relative));

I dont have any clue how to solve it. It would be great if you can provide some pointers

Answer 1

If you need to call it from the main UI thread, use this:

Dispatcher.BeginInvoke(() =>
{
    NavigationService.Navigate(new Uri("/PhotoPreview.xaml", UriKind.Relative));
});
