unoplatform/uno 3.11.6 on GitHub

Uno Platform's 3.11 release ships 160+ features and bug fixes and adds support for .NET 6 RTM with all related improvements.

As Microsoft had announced the delay for .NET 6 support for Android and iOS, we've re-introduced Xamarin-based templates for Visual Studio 2022. Additionally, the support for preview .NET 6 Android and iOS has now been moved to 17.1 Preview 1.

In Visual Studio 2022, you'll find now two templates:

One named Multi-Platform App (UnoPlatform|xamarin), which uses the existing stable Xamarin "Classic". It is the same as found when using Visual Studio 2019.
One named Multi-Platform App (UnoPlatform|net6), which uses the .NET 6 preview support for iOS, Android, macOS and Catalyst and requires Visual Studio 17.1 preview 1.

You can setup your environment with Uno.Check 1.0.2 for Windows, macOS and Linux, which you can install as follows:

dotnet tool install -g uno.check

Then run:

uno-check

Here's a summary of the features for this release:

Support for VS 2022 and .NET 6 RTM
Drag and drop preview element support on iOS and Android
NumeralSystemTranslator for Arab Numeral System
Native pointer captures for GTK
FileSavePicker for Gtk
Support for RadioMenuFlyoutItem
Support for IncrementNumberRounder and SignificantDigitsNumberRounder
Support of GetPeerRadioAsync

As always, many thanks to our contributors:

@pjgpetecodes for a Raspberry Pi tutorial
@thomasclaudiushuber, @xperiandri, for documentation updates
@MohammadHadi2031 for the SignificantDigitsNumberRoundersuport
@pkar70 for the support of GetPeerRadioAsync
@Jadhielv for dotnet new templates updates
@trungnt2910 for UIElement clipping updates
@workgroupengineering for Hot Reload performance updates
