App startup and lifecycle

Lifecycle management in .NET MAUI is crucial for efficient resource management, ensuring smooth and consistent user experiences, secure application handling, and understanding and troubleshooting app behavior. It allows the application to conserve resources, appropriately saving and restoring the application’s state when it’s in the background or foreground. It provides opportunities to perform certain actions when an app goes to the background, such as saving data or pausing activities. Moreover, it provides enhanced security by managing sensitive data when apps switch to and from the active state. Hence, understanding the application lifecycle is crucial for crafting robust, efficient, and user-friendly .NET MAUI applications.

In .NET MAUI projects, app startup and lifecycle management are handled in the following two files:

• MauiProgram.cs
• App.xaml/App.xaml.cs
