Overview of this book

Xamarin is a leading cross-platform application development tool used by top companies such as Coca-Cola, Honeywell, and Alaska Airlines to build apps. Version 4 features significant updates to the platform including the release of Xamarin.Forms 2.0 and improvements have been made to the iOS and Android designers. Xamarin was acquired by Microsoft so it is now a part of the Visual Studio family. This book will show you how to build applications for iOS, Android, and Windows. You will be walked through the process of creating an application that comes complete with a back-end web service and native features such as GPS location, camera, push notifications, and other core features. Additionally, you’ll learn how to use external libraries with Xamarin and Xamarin.Forms to create user interfaces. This book also provides instructions for Visual Studio and Windows. This edition has been updated with new screenshots and detailed steps to provide you with a holistic overview of the new features in Xamarin 4.

In this chapter, we started out learning the process of setting up iOS provision profiles to deploy to iOS devices. Next, we looked at the required device settings for deploying your application to an Android device. We discovered the Xamarin linker, and how it can make your applications smaller and more performant. We went over the various settings for resolving problems caused by your code and the linker, and we explained AOT compilation on iOS and the limitations that occur. Finally, we covered the most common memory pitfalls that can occur with Xamarin applications.

Testing your Xamarin application on mobile devices is important for various reasons. Some bugs are only displayed on the device due to the platform limitations that Xamarin has to work around. Your PC is much more powerful, so you will see different performance using the simulator compared to on a physical device. In the next chapter, we'll create a real web service using Windows Azure to drive our XamChat application...
