# .NET MAUI Shell Navigation Implement page navigation in .NET MAUI apps using Shell. Shell provides URI-based navigation, a flyout menu, tab bars, and a four-level visual hierarchy — all configured declaratively in XAML. ## When to Use - Setting up top-level app navigation with tabs or a flyout menu - Navigating between pages programmatically with `GoToAsync` - Passing data between pages via query parameters or object parameters - Registering detail-page routes for push navigation - Guarding navigation with confirmation dialogs (e.g., unsaved changes) - Customizing back button behavior per page ## When Not to Use - Deep linking from external URLs or app links — see [.NET MAUI deep linking docs](https://learn.microsoft.com/dotnet/maui/fundamentals/app-links) - Data binding on navigation target pages — use `maui-data-binding` - Dependency injection for pages and view models — use `maui-dependency-injection` - Apps using `NavigationPage` without Shell (different navigation API) ## Inputs - A .NET MAUI project with `AppShell.xaml` as the root shell - Pages (`ContentPage`) to navigate between - Route names for detail pages not in the visual hierarchy ## Rules That Change the Answer These are the Shell-specific decisions that are easy to get wrong. Apply them whenever they are relevant to what the user asked. | Situation | Do this | Not this | |---|---|---| | Declaring pages in `AppShell.xaml` | With `xmlns:views="clr-namespace:MyApp.Views"` declared: `<ShellContent Cont...
