Overview of this book

While UI plays a pivotal role in retaining users in a highly competitive landscape, maintaining the same UI can be tricky if you use different languages for different platforms, leading to mismatches and un-synced pages. In this book, you'll see how .NET MAUI allows you to create a real-world application that will run natively on different platforms. By building on your C# experience, you’ll further learn to create beautiful and engaging UI using XAML, architect a solid app, and discover best practices for this Microsoft platform. The book starts with the fundamentals and quickly moves on to intermediate and advanced topics on laying out your pages, navigating between them, and adding controls to gather and display data. You’ll explore the key architectural pattern of Model-View-ViewModel: and ways to leverage it. You’ll also use xUnit and NSubstitute to create robust and reliable code. By the end of this book, you’ll be well-equipped to leverage .NET MAUI and create an API for your app to interact with a web frontend to the backend data using C#.

Understanding the structure of XAML

XAML files have the .xaml extension, for example, MainPage.xaml, in the out-of-the-box program as shown in Chapter 1. Let’s examine this file to explore XAML for its layout and declaration of controls.

Just an overview

This chapter will only scratch the surface of creating XAML layout and controls. Chapter 4 and Chapter 5 will cover the details on controls and layouts, respectively.

A .NET MAUI page that is written in XAML will have a name in the format MyName.xaml, and associated with that page will be a code-behind page (explained shortly) in the format MyName.xaml.cs.

At the top of the XAML page is a declaration that this file is, in reality, an XML-type file. That declaration must be at the very top of every .xaml file.

There are different types of pages (also called views). The most common is ContentPage, and here MainPage is created as ContentPage using this code:

<?xml version="1.0" encoding="utf...
