Uno Platform 4.4 is our 4th release in 2022, keeping us on a once-in-six-weeks rapid release schedule we aim for. The release packs numerous UI and performance improvements across all target platforms. First, on the UI side you’ll be able to produce beautiful fluid animations on .NET Android, .NET iOS and Skia-based targets, as well as increase high-fidelity renderings of all your texts on Skia-based targets. Second, on the performance side we are including support for the most recent WebAssembly advances available in .NET 7 – Wasm Threading and Exception Handling. Lastly, we also enabled new input scenarios via GamePad API support and improved the default project templates. In total we have implemented and resolved over 90 new feature requests and issues.

View the full announcement in our blog post.

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

Uno Platform 4.1 Update for .NET 6 Mobile Preview 14 and VS 2022 17.2 Preview 2

The .NET team has been steadily releasing a set of updates to the .NET 6 Mobile previews. Last week's update was Preview 14, which came at just about the same time as Uno Platform 4.1 release. Following .NET 6 mobile Preview 14, we’re publishing the Uno Platform 4.1.9 service update.

This update includes a new set of binary breaking changes added in .NET 6 Mobile Preview 14, which requires the use of Visual Studio 17.2 Preview 2. If you update to Preview 2, you will need to be on Uno Platform 4.1.9 or later.

Using .NET 6 Mobile Preview 14 with Uno Platform projects

To use this new preview in Uno Platform projects, you’ll need a few steps:

• Install the latest uno-check preview

  dotnet tool install -g uno.check --version 1.2.0-dev.10
  

• Or update to the latest uno-check preview

  dotnet tool update -g uno.check --version 1.2.0-dev.10
  

• Then run the following:

  uno-check --pre 
  

• If you’re building on a mac, either directly or through VS for Windows, you’ll need to run uno-check on the mac as well.

• Make sure that your Visual Studio 2022 Uno Platform extensions are updated to 4.1.9 (it should be automatically updated)

• Update your nuget packages to Uno.UI.* 4.1.9 or create a new project from the templates.

Note that if you intend to build for iOS, Xcode 13.3 is required and that this version of requires macOS Monterey.

It has been just over 3 months since our 4.0 release, and we’ve used that time to focus on performance as well as bringing the latest .NET 6 and even .NET 7 innovation to Uno Platform. By simply updating your application to the newest bits you will notice a significant boost to your app performance.

This release packs over 200 new feature requests, bugs, and issues you raised. We welcomed a few great contributions from our community which is now over 210 contributors strong! Thanks for all you bring to Uno Platform.

For more information about the release, read our blog post.

Important note about .NET 6 Mobile support

The current support for .NET 6 Mobile Preview 13 requires VS 2022 17.2 Preview 1 or later, 17.0.x and 17.1.x are not supported, and naturally Uno Platform will face the same constraints. It’s also worth noting that with .NET 6 mobile Preview 14, Microsoft will introduce an additional (and likely final) set of binary breaking changes, and we’ll publish an update to Uno nuget package to align with those changes.

Once you have 17.2 Preview 1 or later installed, use uno-check --preview to setup your environment.

For a comprehensive description of the Uno 4.0 release, please read our blog post.

As we’re continuing the alignment with the WindowsAppSDK, we’ve made some binary and source breaking changes in the Uno.UI 4.0 NuGet packages.

Most of these changes are minor and are generally present to remove the use of uno-specific conditional code. You can find additional information on how to migrate to Uno 4.0 on our documentation site.

• Some classes are now static to match UWP.
• Some properties now no longer have setters to match UWP.
• ComboBox now inherits from Selector rather than ListViewBase, to match the UWP/WinUI inheritance hierarchy.
• CoreDispatcher.Main is no longer public.

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
