Gets the NavigationService that is used by this Frame to provide navigation services.

Namespace:   System.Windows.Controls
Assembly:  PresentationFramework (in PresentationFramework.dll)

public NavigationService NavigationService { get; }

Property Value

Type: System.Windows.Navigation.NavigationService

A Frame object that represents the NavigationService used by this Frame, if one is available. Otherwise, null is returned.

Frame uses NavigationService to support navigation for hosted content. NavigationService is useful for code that hosts a Frame to get a reference to the NavigationService. Content that is hosted by a Frame, such as Page, should use GetNavigationService or NavigationService to get a reference to the NavigationService.


NavigationService does not return a reference to the same NavigationService as calling GetNavigationService and passing Frame does. The former returns the NavigationService that is owned by the Frame while the latter returns the NavigationService for the navigation host that navigated to the content in which the Frame is hosted. The following code demonstrates the differences.
