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#.

Keeping the user informed of activity

There are two ways to let the user know that your application is working on something time-consuming:

  • ActivityIndicator
  • ProgressBar

ActivityIndicator essentially says, “I’m working on it, but I don’t know how long it will take,” whereas ProgressBar says, “I’m working on it, and I’m about halfway done.” Let’s explore each of these in a bit more detail.


We’ll start by adding ActivityIndicator to the login page below the Buttons:

    IsRunning="{Binding ActivityIndicatorIsRunning}" />

Notice that the IsRunning property is bound to the ActivityIndicatorIsRunning property. That property is in LoginViewModel (you’ll remember that we set that file as the binding context):

[ObservableProperty] private bool activityIndicatorIsRunning...
