.NET Multi-platform App UI (.NET MAUI) is a cross-platform framework for creating native mobile and desktop apps with C# and XAML.​ Using .NET MAUI, you can develop apps that can run on Android, iOS, macOS, and Windows from a single shared code-base.

Will .NET MAUI replace Xamarin Form?

.NET MAUI is the evolution of Xamarin.Forms, a cross-platform mobile first framework for Android, iOS, and UWP.​

Goals of .NET MAUI

  • Quality
    • Fix existing issues of Xamarin
    • Reorganized project structure
    • Standardized class naming and structure
  • Performance
    • Improve code start time
    • Responsive UI rendering, animations and transitions
    • Reduced view nesting
  • Design
    • Simple and elegant default UI theme
    • Easy control extensibility
    • Quick cross platform templating
  • Platform:
    • Android, iOS, MacOS, Windows

.NET MAUI highlight?

  • Architecture:
    • In a .NET MAUI app, you write code that primarily interacts with the .NET MAUI API. ​.NET MAUI then directly consumes the native platform APIs. In addition, app code may directly exercise platform APIs, if required.
  • Single Project
    • MAUI provides a multi-targeting system that allows one to have a single project holding both shared code and resources, as well as platform-specific code and resources underneath a Platforms folder.
  • MVU Design Pattern
    • MVU (Model – View – Update): This pattern provides a unified way to build cross-platform native front ends from a single code base. It also allows us to write UI code and logic in C# as shown below.
  • Blazor:
    • .NET MAUI integrates with Blazor, so you can reuse existing Blazor web UI components directly in native mobile and desktop apps.​
    • .NET MAUI executes your Blazor components natively on the device (no WebAssembly needed) and renders them to an embedded web view control​
    • You can even add native UI controls alongside your Blazor web UI. This is an all new kind of hybrid app: Blazor Hybrid!
  • Hot reload: C# and XAML hot reload
