Introducing .NET Multi-platform App UI (MAUI)

.NET MAUI is:

  • Multi-platform native UI
  • Deploy to multiple devices across mobile & desktop
  • Using a single project, single codebase
  • Evolution of Xamarin.Forms
  • .NET 6

Build Status

Private Public
Build Status Build Status

Maui.sln

SDKS required

dotnet tool install Cake.Tool -g

Running

IDE

  • If you have Visual Studio 16.9 P4 installed you can open Maui.sln and run it from there.

.NET 6

You can run a Cake target to bootstrap .NET 6 in bin\dotnet and launch Visual Studio:

dotnet cake --target=VS-NET6

NOTE: VS Mac is not yet supported.

You can also run commands individually:

# Provision .NET 6 in bin\dotnet
dotnet build src\DotNet\DotNet.csproj
# Builds Maui MSBuild tasks
.\bin\dotnet\dotnet build Microsoft.Maui.BuildTasks-net6.sln
# Builds the rest of Maui
.\bin\dotnet\dotnet build Microsoft.Maui-net6.sln
# (Windows-only) to launch Visual Studio
.\eng\dogfood.ps1

To build & run .NET 6 sample apps, you will also need to use .\bin\dotnet\dotnet:

.\bin\dotnet\dotnet build src\Controls\samples\Controls.Sample.Droid\Maui.Controls.Sample.Droid-net6.csproj -t:Run
.\bin\dotnet\dotnet build src\Controls\samples\Controls.Sample.iOS\Maui.Controls.Sample.iOS-net6.csproj -t:Run

Try out a "single project", you will need the -f switch to choose the platform:

.\bin\dotnet\dotnet build src\Controls\samples\Controls.Sample.SingleProject\Maui.Controls.Sample.SingleProject.csproj -t:Run -f net6.0-android
.\bin\dotnet\dotnet build src\Controls\samples\Controls.Sample.SingleProject\Maui.Controls.Sample.SingleProject.csproj -t:Run -f net6.0-ios

Status: Active Development

While Xamarin.Forms continues to be actively supported through November 2022, we are making evolutionary changes based on customer research of what would be most beneficial. Current areas of focus are:

  • Porting renderers to handlers (spec)
  • Adapting layouts for handlers
  • WinUI 3 preview 3 early spike (branch)
  • Mac Catalyst early evaluation (wiki)

Active development is happening today to build Android and iOS SDKs against .NET 6. Samples may be found here.

Goals

  • Improve app performance
  • Improve simplicity of control extensibility
  • Improve simplicity of contributing
  • Enable developer options to use Model-View-Update (MVU) and Blazor

Roadmap

.NET MAUI and mobile SDK support will ship in concert with .NET 6. At present we do not have a shipping schedule for .NET 6.

Milestones

  • .NET MAUI previews Q4 2020 through Q3 2021
  • .NET MAUI release candidate September 2021
  • .NET MAUI general availability November 2021

* The Windows implementation is expected to be WinUI 3, pending GA release.

** These app models are experimental.

*** Visual Studio Code will work by virtue of .NET unification, however not all experiences that make .NET MAUI development delightful (intellisense for example) may be enabled at the time of .NET 6 release.
