# 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)
* Targeting .NET 6, previews end of year

## Status: Planning and Early Development

While [Xamarin.Forms](https://github.com/xamarin/xamarin.forms) continues to be actively developed to meet customer needs today, we are [proposing evolutionary changes](../../issues) based on some early customer research of what would be most beneficial.

Active development is happening today to build Android and iOS SDKs against the next version of .NET. [Samples may be found here](https://github.com/xamarin/net5-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
* .NET MAUI release candidate September 2021
* .NET MAUI general availability November 2021
