Mastering Xamarin.Forms - Second Edition: Build rich

Publishers Note: This edition from 2018 is outdated. A new third edition, updated for Xamarin.Forms 4, has now been published.

Key Features

• Packed with real-world scenarios and solutions to help you build professional grade mobile apps with Xamarin.Forms
• Build an effective mobile app architecture with the Xamarin.Forms toolkit
• Maximize the overall quality of your Xamarin.Forms apps

Book Description

Discover how to extend and build upon the components of the Xamarin.Forms toolkit to develop effective, robust mobile app architecture. Starting with an app built with the basics of the Xamarin.Forms toolkit, well go step by step through several advanced topics to create a solution architecture rich with the benefits of good design patterns and best practices.

Well start by introducing a core separation between the apps user interface and the apps business logic by applying the MVVM pattern and data-binding. Then we will focus on building out a layer of plugin-like services that handle platform-specific utilities such as navigation and geo-location, as well as how to loosely use these services in the app with inversion of control and dependency injection. Next well connect the app to a live web-based API and set up offline synchronization. Then, well dive into testing the app logic through unit tests. Finally, we will setup Visual Studio App Center to automate building, testing, distributing and monitoring the app.
