Toast notifications

Toast notifications are often used to inform users about things that apply to our application. It could be information about messages, invitations, and so on. We are going to create a simple method that shows a sample message, and after clicking, it goes directly to one of the pages in the application.

public static void ShowSettingsToast()
  var toastMessage = new ShellToast();
  toastMessage.Title = "Hello";
  toastMessage.Content = "Your app settings needs your attention";
  toastMessage.NavigationUri = new Uri("/Views/SettingsPage.xaml", UriKind.Relative);

Implementation is very simple; it's just an initialization of the ShellToast object that contains Title, Content, and NavigationUri and that points to our application page. Calling this method in background agent causes the notification to be seen when the application is not running.
