Mastering Cross-Platform Development with Xamarin

Overview of this book

The main goal of this book is to equip you with the required know-how to successfully analyze, develop, and manage Xamarin cross-platform projects using the most efficient, robust, and scalable implementation patterns. This book starts with general topics such as memory management, asynchronous programming, local storage, and networking, and later moves onto platform-specific features. During this transition, you will learn about key tools to leverage the patterns described, as well as advanced implementation strategies and features. The book also presents User Interface design and implementation concepts on Android and iOS platforms from a Xamarin and cross-platform perspective, with the goal to create a consistent but native UI experience. Finally, we show you the toolset for application lifecycle management to help you prepare the development pipeline to manage and see cross-platform projects through to public or private release.

Application data


Application data makes up the core of the data storage on Xamarin platforms and Windows Runtime. This data is specific to your application. It lives and eventually dies with it, and in most cases it is not relevant or even accessible by other applications running on the same device or even by the user who is using the application (at least directly).

The application has unrestricted access to application data, or so-called isolated storage, without having to ask for permission from the user or add a declaration and can (in most cases) write, read, and query items in this storage according to the type of the application data location.

Installation directory

The installation directory is the innermost part of the accessible data storages and is the most intimate location for the application. Access to this location by the application is unrestricted but read-only. The access models on iOS, Android, and Windows Runtime vary greatly.
