WinUI 3 takes a whole new approach to delivering Windows UI components and controls and has the ability to deliver the same features across multiple versions of Windows. Learn WinUI 3 is a comprehensive introduction to WinUI and Windows apps for anyone who is new to WinUI and XAML applications. This updated second edition begins by helping you get to grips with the latest features in WinUI and shows you how XAML is used in UI development. The next set of chapters will help you set up a new Visual Studio environment, develop a new desktop project, incorporate the Model-View-ViewModel (MVVM) pattern in a WinUI project, and develop unit tests for ViewModel commands. Next, you’ll cover the basics of data access from WinUI projects with a step-by-step approach. As you advance, you’ll discover how to leverage the Fluent Design System to design beautiful WinUI applications. You’ll also explore the contents and capabilities of the Windows Community Toolkit and learn how to create cross-platform apps with markup and code from your project using Uno Platform. The concluding chapters will teach you how to build, debug, and deploy apps to the Microsoft Store. By the end of this book, you’ll have learned how to build WinUI applications from scratch and how to modernize existing desktop apps using WinUI 3 and the Windows App SDK.

I purchased Learn WinUI3 Second Edition in March 2024 and started working through the chapters. In Chapter 3 the book falls apart. The code in the book does not resemble the code on github. The sample application was poorly chosen in my opinion. It makes little sense and then the books code does not work. I thought it was just my lack of experience until I saw comments on the book's github repos. Hopefully better sources will emerge on this topic soon.

Though the content of my book was good and I did gain some value from the purchase. Within the book, there were several grammatical errors, incomplete examples, and syntax errors.

I start a new Job soon writing WinUI3 programs and I didn't found any good resource to understand the whole package of WinUI3. Then I found this book and thought it would be a nice resource to learn everything before starting the Job.The first two Chapters were great and understandable. These chapters helped me a lot. Though starting from Chapter 3 this book went downhill fast. The author suddenly stopped explaining stuff and just advices to copy the code from the github repo. Learning effect = 0. You have to puzzle together what you need to add or what you need to change. No explanation what you did and why you did it. The author suddenly renames whole methods for one page and assumes that you will somehow make it right. For example : he names a method in Chapter 4 "RegisterComponents" which returns nothing (void) then suddenly the method is called "RegisterServices" and returns "IServiceProvider" which won't be returned in the code example from the book - looking in the github repo there is no method called "RegisterServices" and the changes explained are done inside "RegisterComponents". It feels like the Author couldn't decide if he wants to write this book for people experienced in .NET GUI Frameworks or not. Concepts explained and whole chapters resolve around concepts you'd learn as a newbee but the way its explained (and skipped through) it rather feels like he assumes you already are very familiar and can work around it yourself.And one of the worst things in my opinion are the order he does stuff. Instead of starting from the beginning and working up, he starts with "easier" stuff that doesn't make sense when you didn't do the backbones of the changes you're about to do. Like for example starting in the View and then creating ViewModel or anything. You don't know why you do stuff - the IDE cant autocomplete because it doesn't know yet what data structures you are going to implement etc.If you're a bloody beginner you're screwed. Luckily I am not and somehow work around this confusing writing.I am now in the midst of chapter 4 and need to pause every few pages since its so exhausting how confusing this book is written and how much effort I have to put in to "fix" what the author should explain and show.I'd only recommend this book if you really want or need to learn WinUI3 since its the only available resource besides official documentation and figuring out yourself.Very sad considering I had really much fun the first two chapters.

I recently had the pleasure of reading a preview copy of "Learn WinUI 3," and I must say, it exceeded my expectations. The chapter on packaging and deploying a completed app was particularly impressive. All the directions were clear and complete, making the typically frustrating process a breeze. If there’s an area for improvement, I wished it had more examples of simple applications. However, this book is well-written and highly recommended for anyone looking to master WinUI,
