Charles Petzold informs its readers that this book has been particularly written keeping in mind the future of the Xamarin.Forms developers, and in this book, he has provided with summaries (or abstract) of sorts for each chapter. Each summary goes on to describe the corresponding chapter and also contains links to the documentation for each APIs which has been described in the chapter, links to the sample code from that particular chapter, links to related Xamarin.Forms guides, as well as link to the entire chapter.
The summaries would allow its readers to learn Xamarin.Forms in a structured, step by step manner along with minimal amount of reading. By reading the summaries, you will be able to check if a particular chapter has information which you might need, before you consult the entire chapter for more detailed information.
