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.

Multithreading on Xamarin

Xamarin platforms together with Windows Runtime follow the basic principles of a single-threaded apartment model. In this model, in simple terms, a process is assigned a single thread which acts as the main trunk for all the other possible branches to be created from and yield back to.

While developers still have the ability to create and consume multiple threads, in modern applications on Xamarin target platforms, this model has been extended with concurrency implementations that delegate the responsibility of thread management to runtime and allow the developer only to define execution blocks which may or may not be executed on a separate thread.

Single thread model

In Android and iOS, each mobile application is started and run on a single thread that is generally referred to as the main or the UI thread. Most of the UI interaction and process lifecycle event handlers and delegates are executed on this thread.

In this model, developers' main concern should be keeping...
