.NET MAUI for C# Developers

3.7 (6)
By: Jesse Liberty, Rodrigo Juarez

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#.

Technical requirements

To follow along with this chapter and book, you will need to obtain and install Visual Studio and Git. To do this, you will need a Windows machine (Windows 10 or later). In addition, if you want to write for iOS and/or the Mac, you will need an Apple computer on the same network as your Windows computer.

All of the code in this book is available at https://github.com/PacktPublishing/.NET-MAUI-for-C-Sharp-Developers. The code for each chapter will have its own branch and that will be noted in the Technical requirements section of the given chapter. Note that there is no code for Chapters 1 and 2.

A word on Visual Studio Mac

It should be possible to follow along with this book using Visual Studio Mac, but some of the menus and certainly many of the keystrokes will be different. In my experience, Visual Studio Mac follows Visual Studio with a short delay in the implementation of new features. If all you have is a Mac, by all means do your development there. If you have both, or just a Windows machine, you’ll find it a bit easier to follow along with Visual Studio (for Windows).

While I’m at it, I’ll mention that I’m using Windows 11 on a desktop computer with 64 GB of memory and a 1 TB disk. None of that is required for this book. You will want at least 16 GB of memory for .NET MAUI programming.
