The release packs numerous UI and performance improvements across all target platforms.

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.

Uno Platform 4.3 – Figma Plugin, Uno Extensions, Material Design 3 Support, New Sample App and more

Uno Platform 4.3 is here! The focus of this release was on enhancing our Figma plugin which generates your app XAML directly from Figma designs, as well as advancing Uno Extensions to help bootstrap your apps faster.   When looking at overall productivity and speed at which applications need to be developed, organizations need to consider the full application lifecycle. The application development lifecycle starts much earlier than coding, in the UX/UI design process. Also, the application needs to be bootstrapped quickly so that all members of the development team can start building real value.  We believe that using Uno Platform and its multi-platform capabilities, in combination with Figma integration and Uno.Extensions provide an optimal solution for increasing developer productivity and reducing time to market.   To make it easy for you to learn and experience all these concepts we are unveiling a new sample app –  “Uno To Do” app – with all assets included – from its Figma design files and code which shows how Uno Platform and Uno Extensions work on mobile, desktop and Web.   Figma Plugin and Material 3 Theme Update Uno Platform plugin for Figma is how you go from high fidelity Figma designs to developer-friendly XAML

Uno Platform 4.2 – .NET 6 Mobile RC1, Perf Boost, 190+ Improvements

.NET 6 Mobile RC1 Support 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. 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

Uno Platform 4.1 Update for .NET 6 Mobile Preview 14

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 Visual Studio 17.2 Preview 2, you will need to be on Uno Platform 4.1.9 or later.  To use this new preview in Uno Platform projects, you’ll need a few steps:  Update to the latest uno-check preview dotnet tool update -g uno.check –version 1.2.0-dev.10 and then run uno-check –pre Update your NuGet packages to Uno.UI.* 4.1.9 or create a new project from the templates 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) Note that if you intend to build for iOS, Xcode 13.3 is required and that this version

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 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. Let’s unpack the 4.1 release. Performance updates For this release, we’ve made numerous changes to a wide range of parts from the Uno Platform, such as Style resolution, layout and measure pass performance, memory consumption and allocations which result in up to 30% performance improvements in some scenarios. Measure Dirty Path The measure pass (MeasureOverride and InvalidateMeasure) is an important contributor to the computations performed to layout the UI, and any optimization performed in this area can significantly improve the time to show the first UI or improve binding update. We’ve changed the way MeasureOverride is invoked when InvalidateMeasure is called, where previously all ancestors of a control would be re-executing MeasureOverride,

Uno Platform Extensions To help you bootstrap a new Uno Platform application and get started with proper architecture we are introducing Uno Extensions. The idea is you shouldn’t need to ever write code from scratch for commonly used functions, while retaining an option to easily extend any feature.  Microsoft has extracted a host of capabilities outside of ASP.NET and made them available through Microsoft Extensions – covering hosting, logging, configuration, etc. In turn, Uno Platform Extensions are based on Microsoft Extensions. Reactive (MVU-X) While we have ~10 extensions available, Reactive is one of the bigger ones and deserves special attention. In our
