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 serverless backend

Let's start setting up the backend based on the services described in the preceding section.

Creating a SignalR service

The first service that we will set up is the one for SignalR. To create such a service, proceed as follows:

  1. Go to the Azure portal, at
  2. Create a new resource. The SignalR Service resource is in the Web category.
  3. Fill in a name for the resource in the form.
  4. Select the subscription you want to use for this project.
  5. We recommend that you create a new Resource group and use it for all the resources that we will create for this project. The reason that we want one resource group is that it is easier to track which resources are related to this project, and it is also easier to delete all the resources together.
  6. Select a location that is close to your users.
  7. Select a pricing tier. For this project, we can use the Free tier. We can always use the Free tier for development, and later scale up to a tier that can...
