# 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](https://github.com/xamarin/xamarin.forms)
|
|
* .NET 6
|

## Maui.sln
|
|
|
|
### SDKS required
|
|
- Install the SDKs listed here https://github.com/xamarin/net6-samples
|
|
|
|
- And/or run the following
|
|
|
|
```
|
|
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:
|
|
|
|
```dotnetcli
|
|
dotnet cake --target=VS-NET6
|
|
```
|
|
_NOTE: VS Mac is not yet supported._
|
|
|
|
You can also run commands individually:
|
|
```dotnetcli
|
|
# 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`:
|
|
```dotnetcli
|
|
.\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:
|
|
|
|
```dotnetcli
|
|
.\bin\dotnet\dotnet build src\Controls\samples\Controls.Sample.SingleProject\Maui.Controls.Sample.SingleProject.csproj -t:Run -f net6.0-android --no-restore
|
|
.\bin\dotnet\dotnet build src\Controls\samples\Controls.Sample.SingleProject\Maui.Controls.Sample.SingleProject.csproj -t:Run -f net6.0-ios --no-restore
|
|
```
|
|
|
|
Note that `--no-restore` is a workaround until [dotnet#15485](https://github.com/dotnet/sdk/issues/15485) is fixed in a future preview.

## Status: Active Development
|
|
|
|
While [Xamarin.Forms](https://github.com/xamarin/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](https://github.com/dotnet/maui/issues/28))
|
|
* Adapting layouts for handlers
|
|
* WinUI 3 preview 3 early spike ([branch](https://github.com/xamarin/Xamarin.Forms/tree/winui3))
|
|
* Mac Catalyst early evaluation ([wiki](https://github.com/xamarin/xamarin-macios/wiki/Mac-Catalyst-(Early-Preview)))
|
|
|
|
Active development is happening today to build Android and iOS SDKs against .NET 6. [Samples may be found here](https://github.com/xamarin/net6-samples).
|
|
|
|
### 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
|
|
* [Renderer architecture revisions](https://github.com/dotnet/maui/issues/28)
|
|
* Source solution and project simplification
|
|
* Complete approved proposals
|
|
* Implement MVU (experimental)
|
|
* .NET MAUI release candidate September 2021
|
|
* .NET MAUI general availability November 2021

<sup>***</sup> 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.
