Mastering Xamarin.Forms - Third Edition: App architecture techniques for building multi-platform, native mobile apps with Xamarin.Forms 4

I have a complaint as a non-corporate programmer is available training. You see a new methodology or framework and go I think that maybe just what I need? Your first look is say Microsoft. There you find a couple of pages where they give you just the bare essentials. From there you start your journey. Web sites all over that basically copy the same examples used on Microsoft with zip added or a web site where they jump to some advanced manipulation of video on a phone..... This book is not any of that! This book which I'm about half way through is showing you how to build a practicle application giving you all the things you need. Like authorization, Testing, Monitoring, Azure Functions. A real example, great book!

I am trying to learn Xamarin Forms and gave this book a try. Well after having error message and spending weeks and weeks of googling with no results I finally got in touch with the author. He would not respond to the tweets that I sent him so i seen he works with another company. I Tweet them and next thing you know Ed got back with me. I explained to him the issue I was having and he requested pictures and section i was having issues with. I sent screenshots and a text letter explaining area of the book errors where occurring. He never got back with me and after several weeks of googling and posting to several Facebook groups i was able to find the answer. I found out a lot of people was having the same issue. Finally Ed got back with and I gave him the results of my research and a new error i found in his book. He never emailed back to help or even to thank me for helping him when he doesn't care to help me. VERY AWFUL AUTHOR.

This book is very good about build MVVM apps using Xamarin. While it is written for VS Mac, it will work with VS Windows.One of things about Xamarin is that like Java, there is a lot of coding you see in the examples that doesn't make a lot of sense right away. The book tells you what is does but I wish they were better with comments in the examples. If you're going to use the books examples for coding purposes in the future, its a good idea to connect the dots.I wish this book covered editing data in a table. A lot of Xamarin books that I have seen do a poor job of that. I'm only halfway through the book and looked ahead and didn't see any examples in here.

This book is very short and super basic. Almost 1/2 the book is about setting up Azur, and a good 20% is just filler content, 1/2 a page is dedicated to name tools that you can use to expand a zip file. What a joke.

The book is page after page actual working samples and examples. You may skip a chapter, say on Dependency Services; but you will always have a working app. Great as a reference app on your 'backup' drive. I highly recommend Ed Snider

There aren’t a lot of great Xamarin books available, but you can add this one to the shortlist. Mastering Xamarin.Forms by Ed Snider is a fantastic reference for mobile developers. If you’re a .NET developer with at least some exposure to Xamarin development, this book will give you the knowledge you need to build great mobile apps with Xamarin.Forms with Visual Studio on your Mac or Windows environment.Snider takes my favorite approach when writing the book. He builds an end-to-end sample app throughout the book, building onto it with the patterns and practices learned in each chapter. For me, getting hands-on and building a real-world app while reading a book or watching a video training course reinforces the lessons. The app in this book is a TripLog, which can be used as a travel log or diary.After creating the project and a couple of initial screens, Snider dives right into some patterns for mobile app development, starting with the MVVM (model-view-view model) pattern. With each pattern or practice, he explains the concept, how to implement it in Xamarin.Forms and .NET, and then explains how our apps benefit from the implementation. For MVVM, he goes into data binding and validation, which become trivial with the pattern.The next several chapters detail best practices for navigation, leveraging dependency injection to create platform-specific implementations across iOS, Android or UWP on Windows, and some UI tips for handling platform differences through custom renderers. Snider pulls some Azure concepts into the book with Azure Functions. Learn to make API calls from an app service into Azure Functions and then add authentication to Azure Functions and a login screen to the app. I’ve never used any data caching frameworks in my mobile apps, so the section on Akavache for caching was really helpful. It was pretty trivial to add some offline caching to the Xamarin app.The unit testing section is really thorough. I have seen many .NET books that just glance over the topic of unit testing and best practices for testing, but Snider really gives a solid base for readers here. Finally, in the final chapter, monitoring is covered. He mainly explains how to set up Visual Studio App Center to track some usage and the health of the app while it’s running out in the world. When optimally configured, this data can give the information developers need to keep their user base happy and engaged. Kudos to Ed Snider for a really well-written book for Xamarin.Forms developers. I strongly encourage you to check it out if you’re getting serious about building mobile apps.

The blurb on the back cover says “Master Xamarin.Forms, Third Edition is one of the few Xamarin books structured around the development of a simple app from start to finish, beginning with a basic Xamarin.Forms app and going step by step through several advanced topics to create a solution architecture rich with the benefits of good design patterns and best practices”. That’s a fair description. I’ve read a lot of Xamarin.Forms books (probably the majority of Xamarin.Forms books), having been working with Xamarin.Forms solidly for 5+ years, and this is the best example I have seen of building up an app from scratch using good design patterns and practices.Whilst there are parts of the book where I would have liked it to go a bit further, there are bits where I would have liked an explanation of the pros and cons of possible alternatives rather than immediately pursuing one choice, and there are bits that I would do differently in complex apps, for the most part I find myself very satisfied with this book. It’s good to see the way that experienced developers do things. I already make use of some of Ed Snider’s work, using a NuGet that he worked on in my current app, as well as having used some of his code as a starting point that I have then adapted. As a result, I knew that Ed knows his stuff, and this book confirms that.One thing that I am also appreciative of, is that this book is well written and proofread. Whilst I haven’t typed all of the code in to check it, what I haven’t done is highlight error after error in the text, which is what I find myself doing in many of the Xamarin.Forms books that I have read. This one has been written well, so I haven’t been distracted from the technical content by errors in use of language.Recommended for intermediate and advanced developers.

La maggior parte dei capitoli sono scritti chiaramente e sono ordinati nella spiegazione.Altri capitoli, come quelli relativi alla parte dei Custom Renderers e Authentication Servicesnon vengono spiegati proprio nel dettaglio.E' chiaro che alcuni argomenti non riguardano nello specifico la tematica di Xamarin (es. configurazione dei servizi su Azure), ma per chi non li conosce bene seguire gli esempi diventa un problema e a volte si riduce a un copia e incolla degli esempi che poi a volte non funzionano.Tra tutti i libri su Xamarin, questo è quello più aggiornato (al 2019), anche perché gli altri testi usano ancora Xamarin Studio invece di Visual Studio.Testo comunque consigliato per chi vuole approfondire l'argomento.

The book is very thin it goes through a single project. The layout is not bad easy to follow but there are a couple of down falls especially if you’re new to Xamarin:1. It doesnt explain the objects for example it uses Collection view, it would be nice to explain this object and say what are the advantages to say using List View. The book although easy to follow wont bother explaining anything in details. This is also true for installing the API key for Android it gives you a web link to follow instructions which I think is very poor since the project is dependent on having this installed correctly.2. It uses Google maps which means you need to get an API key so if your not comfortable signing up your credit card to what is a free service providing you stay below a certain amount of hits I would say skip this book.Overall I think the price and the size of the book doesnt match, the project idea is not bad using Azure and other usefull tools which will benefit new developers.For those that dont want to use their credit card details, you could use this book minus the Google page but for a new developers I wouldnt recommend this.

The book is well structured for learning the basics of xamarin, however it is written with an old version of Visual studio and as such is no good for a modern setup i.e. xamarin.forms on VS 2019 ~ 2022 does not give the option of using .net and so fails on first build. I thought I was getting a modern update copy of this book but it appears to be just a rehash of the previous one.

Wurde verschenkt. Dem beschenkten gefiel es Sehr.
