Overview of this book

If you're a developer looking to improve and modernize your existing LOB applications to leverage modern Windows features without having to rewrite the entire application from scratch, this book is for you. You’ll learn how to modernize your existing Windows Forms, WPF, and UWP applications and enrich them with the latest Windows features. Starting with sample LOB applications that cover common scenarios, you'll learn the differences between various components and then focus on design features for improved visual aspects like accessibility and responsive layouts. The book shows you how to enhance your existing applications using Windows App SDK components and various Windows APIs, resulting in deeper integration with the operating system. You’ll be taking a closer look at WinML, which enables Windows applications to evaluate machine learning models offline and leverage the power of your machine, or notifications, to engage with your users in a more effective way. You’ll also learn how to make your application deployment-ready by distributing it using various platforms like the Microsoft Store or websites. By the end of this Windows book, you'll be able to create a migration plan for your existing Windows applications and put your knowledge to work by enhancing your application with new features and integrating them with the Windows ecosystem.

Performing operations in the background

Since one of the main goals of UWP is to enable developers to write apps that are respectful of the system resources, its background model is quite restrictive compared to the Win32 one. As we highlighted in the Controlling the application's life cycle section, applications aren't able to freely run in the background, but they are automatically suspended after a few seconds of inactivity. Background activities are still supported but through a unique feature called background tasks, which are independent snippets of code that can perform operations in the background when a specific trigger happens (every 15 minutes, when the user connects to the internet, and so on).

The Windows App SDK, being part of the Win32 ecosystem, removes most of the restrictions around background activities. The biggest one is that applications aren't suspended anymore when they are minimized, which makes it possible to continue running tasks in the...
