eBook Description:

Mastering Xamarin.Forms, 3rd Edition: New edition of the bestselling guide to building an effective mobile app architecture with Xamarin.Forms 4 that maximizes the overall quality of apps: Updated for Xamarin.Forms 4

Discover how to extend and build upon the components of the most recent version of Xamarin.Forms to develop an effective, robust mobile app architecture. This new edition features Xamarin.Forms 4 updates, including CollectionView and RefreshView, new coverage of client-side validation, and updates on how to implement user authentication.

Mastering 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.

• Find out how, when, and why to use architecture patterns and best practices with Xamarin.Forms
• Implement the Model-View-ViewModel (MVVM) pattern and data binding in Xamarin.Forms mobile apps
• Incorporate client-side validation in Xamarin.Forms mobile apps
• Extend the Xamarin.Forms navigation API with a custom ViewModel-centric navigation service
• Leverage the inversion of control and dependency injection patterns in Xamarin.Forms mobile apps
• Work with online and offline data in Xamarin.Forms mobile apps
• Use platform-specific APIs to build rich custom user interfaces in Xamarin.Forms mobile apps
• Explore how to monitor mobile app quality using Visual Studio App Center

This book introduces a core separation between the app’s user interface and the app’s business logic by applying the MVVM pattern and data binding, and then focuses on building 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. You’ll connect the app to a live web-based API and set up offline synchronization before testing the app logic through unit testing. Finally, you will learn how to add monitoring to your Xamarin.Forms projects to track crashes and analytics and gain a proactive edge on quality.
