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#.

Chapter 4, MVVM and Controls

  1. MVVM has two main advantages. First, it is nearly impossible to unit test a .NET MAUI application if your logic is in the code-behind file – putting the logic in ViewModel is essential, as we’ll see in the upcoming chapter on unit testing. Second, MVVM nicely decouples the UI from your logic, allowing you to change one without breaking the other.
  2. The all-important BindingContext. You typically assign ViewModel as the binding context for View.
  3. The Entry control and the Editor control.
  4. The Label control.
  5. SnackBar is a highly configurable Toast – a popup that comes up from the bottom of the page and then can disappear either by its timer running out or by a user clicking on it.
