How to ensure UWP app is always full screen on launch?

To ensure that a UWP app is always full screen on launch, you can set the ApplicationView.PreferredLaunchWindowingMode property to ApplicationViewWindowingMode.FullScreen in the OnLaunched method of your App class. Here's an example:

using Windows.ApplicationModel; using Windows.ApplicationModel.Activation; using Windows.UI.ViewManagement; using Windows.UI.Xaml; using Windows.UI.Xaml.Controls; using Windows.UI.Xaml.Navigation; namespace MyApp { sealed partial class App : Application { public App() { this.InitializeComponent(); this.Suspending += OnSuspending; } protected override void OnLaunched(LaunchActivatedEventArgs e) { // Set the preferred launch windowing mode to full screen ApplicationView.PreferredLaunchWindowingMode = ApplicationViewWindowingMode.FullScreen; // Create and show the main window var rootFrame = new Frame(); rootFrame.Navigate(typeof(MainPage)); Window.Current.Content = rootFrame; Window.Current.Activate(); } private void OnSuspending(object sender, SuspendingEventArgs e) { // Save app data and state } } }

In this example, we set the ApplicationView.PreferredLaunchWindowingMode property to ApplicationViewWindowingMode.FullScreen in the OnLaunched method before creating and showing the main window. This ensures that the app launches in full screen mode by default.

Note that the ApplicationViewWindowingMode.FullScreen value is not supported on all devices, so you may need to provide a fallback behavior or adjust the behavior based on the device type. Additionally, full screen mode can affect the user experience, so it's important to consider whether it's appropriate for your app's use case.
