We are on a monthly cadence of previewing .NET MAUI, and we are happy to announce the availability of preview 11. This release is a bit different, and there are some warnings so please read on before plunging headfirst into updating.

IMPORTANT: If you are actively developing an app with .NET MAUI and need the best Visual Studio experience, we recommend waiting until Visual Studio 2022 (17.1 Preview 2) is available.

At this point in our development, we are making concurrent enhancements to both Visual Studio and SDK feature updates to support .NET MAUI scenarios. For this reason we have been shipping .NET MAUI previews in sync with Visual Studio 2022 previews. Due to issues discovered late in QA in an unrelated workload, we are holding back the Visual Studio 2022 preview that pairs with the .NET MAUI preview 11. This means:

• you must update to preview 11 via the dotnet CLI.
  • dotnet workload update
  • .NET MAUI development instructions
• you must disable XAML Hot Reload in Visual Studio 2022 (17.1 Preview 1)
• you risk having conflicts once 17.1 Preview 2 ships

Highlights

• Fluent Design System styling for Button, Editor, and Entry on Windows
• Multi-window implementation available for Android, iOS, and macOS. Windows is available with an experimental release of Windows App SDK.
• Updated templates with C# 10-ism and item templates for ContentPage and ContentView
• iOS type alignment with .NET 6 - requires recompile of any iOS libs
