What are the main app states in .NET MAUI?

A .NET MAUI app moves through four logical states: Not Running, Running (foreground), Deactivated (visible but no focus), and Stopped (backgrounded).

How do I handle platform-specific events?

You can use the ConfigureLifecycleEvents method in your MauiProgram.cs to hook directly into native callbacks for Android, iOS, and Windows using conditional compilation.

Does the 'Resumed' event fire on the first launch?

No, the Resumed event only fires when the app returns to the foreground from a Stopped state; the initial launch sequence uses Created and Activated.

Where should I save app state during backgrounding?

It is best practice to override the OnStopped method and use Preferences for small data or SecureStorage for larger datasets to ensure state is preserved if the app is terminated.

Manages .NET MAUI application states and window lifecycle events across Android, iOS, and Windows platforms.

This skill provides specialized guidance for handling the complex application lifecycle in .NET MAUI, covering the four primary app states: not running, running, deactivated, and stopped. It enables developers to correctly implement cross-platform window events like OnStart, OnSleep, and OnResume, while offering platform-specific mapping for Android, iOS/Mac Catalyst, and WinUI. By providing standardized patterns for state preservation and transient data recovery, it ensures a seamless user experience during backgrounding and app restoration.
