Summary

UWP introduced many concepts that are still truly relevant today—delivering a modern UI experience, optimized for multiple screens and accessibility; being respectful of the system resources; supporting new technologies, such as modern authentication and artificial intelligence. These are just a few examples of features introduced by UWP that are important to build modern desktop applications.

This is the reason the Windows App SDK and WinUI were built around the same principles, but on top of the Win32 ecosystem to give developers more flexibility and make it easier for them to reuse the existing code and libraries.

Even if many of the building blocks are the same, moving to the Win32 ecosystem means that there are some differences around some key concepts, such as the application's life cycle or windowing management. In this chapter, we learned about these differences in detail as well as what the new APIs you must use to properly support these scenarios...
