Uno Platform 4.2 – .NET 6 Mobile RC1, Performance

As of last week’s release of .NET 6 Mobile RC1, Uno Platform is now following the updates to ensure that you have access to the latest features provided by the .NET runtime.

You can read the full post here.

As per Microsoft’s announcement, the .NET 6 Mobile APIs are now considered stable for iOS, Android, and Mac Catalyst. This enables applications and libraries to be developed without having to deal with any breaking changes in future .NET Mobile releases. As Uno Platform takes a dependency on dotnet runtime, this is important as we can stabilize our own support for iOS, Android and mac Catalyst targets.

Since our previous release about six weeks ago, we also made a batch of changes to fix the support for localization of iOS, macOS and Catalyst apps, based on the new behaviors of .NET 6. In total there were over 190 new features and fixes completed, around Geolocation, focus and keyboard management, Android/Skia/WebAssembly performance, and more. For those who like stats – that’s about 6 closed PRs per business day; we are definitely picking up velocity even more.

As always, to upgrade to the latest bits and use .NET 6 Uno Platform app templates, you’ll need to use uno-check.

You can find up-to-date information about uno-check in our docs.

To install Uno-check:

dotnet tool install -g uno.check

To update Uno-check if you had it installed already

dotnet tool update -g uno.check

You can then run it with:

uno-check --pre

Important note:
If you were already using Uno 4.1.x, had run uno-check and were using VS 17.2 preview 3 or earlier, upgrading to 17.2 Preview 4 or later will cause mobile workloads to become desynchronized. To fix your environment, you’ll need to run the following command:

dotnet workload install ios android maccatalyst macos --from-rollback-file https://aka.ms/dotnet/maui/rc.1.json --source https://aka.ms/dotnet6/nuget/index.json --source https://api.nuget.org/v3/index.json
