Overview of this book

Xamarin.Forms is a lightweight cross-platform development toolkit for building apps with a rich user interface. Improved and updated to cover the latest features of Xamarin.Forms, this second edition covers CollectionView and Shell, along with interesting concepts such as augmented reality (AR) and machine learning. Starting with an introduction to Xamarin and how it works, this book shares tips for choosing the type of development environment you should strive for when planning cross-platform mobile apps. You’ll build your first Xamarin.Forms app and learn how to use Shell to implement the app architecture. The book gradually increases the level of complexity of the projects, guiding you through creating apps ranging from a location tracker and weather map to an AR game and face recognition. As you advance, the book will take you through modern mobile development frameworks such as SQLite, .NET Core Mono, ARKit, and ARCore. You’ll be able to customize your apps for both Android and iOS platforms to achieve native-like performance and speed. The book is filled with engaging examples, so you can grasp essential concepts by writing code instead of reading through endless theory. By the end of this book, you’ll be ready to develop your own native apps with Xamarin.Forms and its associated technologies, such as .NET Core, Visual Studio 2019, and C#.

Building the photo gallery app

It's time to start building the app using the following steps:

Use the Mobile App (Xamarin.Forms) template. The easiest way to find the template is to search for Xamarin.Forms in the search bar at the top of the dialog that appears when we start Visual Studio:

Name the app GalleryApp:

Select the Blank template, and Android and iOS as the platforms:

Update the NuGet packages that are added by the template to make sure that we use the latest versions. We will do so by right-clicking on the solution file and selecting Manage NuGet Packages for solution. Then, select the Update tab, select all the packages, and click Update.

In this project, we will use some C# 8 features. At the time of writing this book, C# 8 is not the default language version. To use it, you need to add <LangVersion>8.0</LangVersion> to each project file.
