Mastering Xamarin.Forms - Second Edition

Create high-quality multi-platform native apps with Xamarin.FormsAbout This BookPacked with real-world scenarios and solutions to help you build professional-grade mobile apps with Xamarin.FormsBuild an effective mobile app architecture with the Xamarin.Forms toolkitFind out how, when, and why you should use architectural patterns and get best practices with Xamarin.FormsWho This Book Is ForThis book is intended for C# developers who are familiar with the Xamarin platform and the Xamarin.Forms toolkit. If you have already started working with Xamarin.Forms and want to take your app to the next level with higher quality, maintainability, testability, and flexibility, then this book is for you.What You Will LearnImplement the Model-View-View-Model (MVVM) pattern and data-binding in Xamarin.Forms mobile appsExtend the Xamarin.Forms navigation API with a custom ViewModel-centric navigation serviceLeverage the inversion of control and dependency injection patterns in Xamarin.Forms mobile appsWork with online and offline data in Xamarin.Forms mobile appsTest business logic in Xamarin.Forms mobile appsUse platform-specific APIs to build rich custom user interfaces in Xamarin.Forms mobile appsExplore how to improve mobile app quality using Visual Studio AppCenterIn DetailDiscover how to extend and build upon the components of the Xamarin.Forms toolkit to develop an effective, robust mobile app architecture. Starting with an app built with the basics of the Xamarin.Forms toolkit, you'll go step by step through several advanced topics to create a solution architecture rich with the benefits of good design patterns and best practices.You'll start by introducing a core separation between the app's user interface and its business logic by applying the MVVM pattern and data-binding. Then you focus on building out a layer of plugin-like services that handle platform-specific utilities such as navigation and geo-location, and on how to loosely use these services in the app with inversion of control and dependency injection. Next you connect the app to a live web-based API and set up offline synchronization. Then, you delve into testing the app logic through unit tests. Finally, you set up Visual Studio App Center for monitoring usage and bugs to gain a proactive edge on app quality.Style and approachThis easy-to-follow, code-rich guide will walk you through building a real-world Xamarin.Forms mobile app from start to finish. Each chapter builds on the app by applying new advanced capabilities, design patterns, and best practices. Packed with real-world scenarios, this step-by-step guide will help you quickly build professional-grade apps with Xamarin.Forms.
