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#.

XAML and Fluent C#

In this chapter, we will look at how .NET MAUI applications are created using a markup language for the user interface and C# for all the logic.

.NET MAUI programs are (typically) written in two languages. One is C#, which is used for all the logic, and the other is XAML (pronounced zamel, to rhyme with camel), which is used for the layout and creation of controls. As you’ll see, the use of XAML is optional. You can create your layout and controls all in C#, but most people don’t. However, that may be changing (more and more of the Microsoft Learn documentation shows both ways).

When might you choose to use C#?

There are a few reasons to use C# instead of XAML, not least that you know C# and don’t want to bother learning XAML. If you do this, however, you’ll find it difficult to read other people’s code, as most existing Xamarin.Forms (the precursor to .NET MAUI) apps are written with XAML.

Using C# can assist in those...
