.NET MAUI: apps for phone and desktop

Build apps for Android, iOS, macOS and Windows from one code base: XAML, MVVM, data that works offline, Blazor components shared with the web application, and delivery.

Who it is for

For everyone after K2 whose employer or project asks for an app for phone and desktop and who wants to stay with C# and the Kladde's stack.

Prerequisites

K2 (C#, the Kladde's web API with sign-in, Blazor components, tests) or the placement test. iOS needs a Mac; the exercises run on Android and Windows.

Afterward, you can

  • Set up and start a .NET MAUI app and explain how it is built
  • Build interfaces in XAML with layouts, CollectionView and Shell navigation
  • Build pages with MVVM and the MVVM Toolkit and test the view models without a device
  • Load data through the web API, sign in safely and carry on offline in SQLite
  • Use Blazor components in a shared Razor class library for web and app
  • Build and sign packages for Android and Windows
