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#.

You can fill in the color of any number of controls using a brush. The easiest place to see this in action is with a BoxView control, or with Frame.

There are three types of brushes, Solid, Linear Gradient, and Radial Gradient. Let’s explore them in a bit more detail.

The Solid brush

The Solid Brush is used when you want to fill a control with a single color. Typically, the solid brush is implicit in the BackgroundColor property of the control, as we saw above when drawing the BoxView control.


LinearGradientBrush paints an area with a blend of two or more colors along a line called the gradient axis. You specify a start point and an endpoint, and then you specify stop points (where the colors switch) along the way.

The start and endpoints are relative to the borders of the painted area, with 0,0 being the upper left corner (and the default start) and 1,1 being the lower right (and the default stop).

To illustrate this, I’...
