Assembly: PresentationFramework (in PresentationFramework.dll)
NavigationWindow uses a NavigationService to provide navigation services to content that is hosted by NavigationWindow. The property is useful for code in a custom NavigationWindow to get a reference to the NavigationService, to handle navigation events, for example.
Content that is hosted by a NavigationWindow, such as Page, should use the NavigationService.GetNavigationService method or Page.NavigationService property to get a reference to the NavigationService.
