In which situations NavigationService.CanGoBack returns false?

Question

Before calling NavigationService.GoBack() we need to check if NavigationService.CanGoBack is true, but what are the situations that NavigationService.CanGoBack returns false?

Answer 1

CanGoBack returns false if there is nothing in the navigation history. There are times when the most recent entry (multiple navigators) may not have been added for the current navigator.
