One of the key aspects of developing robust applications in .NET MAUI is effectively managing app lifecycle events. App handlers allow developers to respond to various states of an application's lifecycle, ensuring seamless user experiences. In this guide, we’ll explore how to implement app handlers in .NET MAUI and make the most of the app lifecycle. Understanding the App Lifecycle Before diving into implementation, it's crucial to understand the app lifecycle in .NET MAUI. The app lifecycle includes various stages that an application goes through from launch to termination. Managing these stages allows developers to maintain the app's state, save data, and release resources appropriately. Key Lifecycle Events Start : Triggered when the app starts. Sleep : Triggered when the app goes into t
