It has been nearly 3 months since we launched Uno Platform 5.0. Since then, .NET RTM’d and even shipped a servicing release. Naturally, we embedded all that goodness in our 5.1 release, as well as added number one feature you requested – Our Live Wizard for Rider and VS Code users.

The same time-saving utility is now available via our Live version to JetBrain’s Rider and VS Code users so you can get your projects set up quickly. We also added three new controls, and improved performance.

Visit our blog post to learn more about Uno Platform 5.1!

A few more detailed highlights on this release :

• Font Fallback support on Skia
• TimePicker support
• New MsBuild Uno.Sdk
• Support for ComboBox.IsTextSearchEnabled
• Support for StandardUICommand
• TextBlock support for IsTextTrimmed and IsTextTrimmedChanged
• Performance
  • Memory leaks improvements (NavigationView, RatingControl)
  • Animations performance improvements
  • Memory allocation and Boxing reductions in DependencyObject
  • StatusBar performance for Android
  • TextBlock rendering performance
• Various alignments in layout engine from WinUI

BREAKING CHANGES

• Uno.WinUI used to have NavigationView both in MUXC and WUXC namespaces. It's now removed from WUXC and kept only in MUXC namespace.

(cherry picked from commit ca19a4d5865f5c6f1dae53b5e3daeb39ab2863d3)

• Fuzzy matching is now disabled by default

(cherry picked from commit ed7855d303f7bd999488e84de886b217ce5b1ef5)

• Resources dictionaries are now required to be explicitly referenced by URI to be considered during resource resolution. This change is present to align the inclusion behavior with WinUI, which does not automatically place dictionaries as ambiently available. This change can be disabled by using FeatureConfiguration.ResourceDictionary.IncludeUnreferencedDictionaries.
• Application.OnWindowCreated does not exist in WinAppSDK
• DependencyObjectGenerator no longer generated an empty ApplyCompiledBindings method.
• EasingFunctionBase API is now aligned with WinUI
• Remove ResourcesService and ResourceHelper
• Move SwipeControl, SwipeItem, SwipeItemInvokedEventArgs, SwipeMode, SwipeItems, and SwipeBehaviorOnInvoked implementation from WUX namespace to MUX namespace.
• Move MenuBar, MenuBarItem, and MenuBarItemFlyout to MUX namespace
• Implicit conversion from string to Point is removed.
• Move AnimatedVisualPlayer, IAnimatedVisualSource , and IThemableAnimatedVisualSource from WUX to MUX
• Rename CreateTheamableFromLottieAsset to CreateThemableFromLottieAsset

• ShouldWriteErrorOnInvalidXaml now defaults to true.
• Deleted dead code and some public APIs.
• GetLeft, GetTop, SetLeft, SetTop, GetZIndex, and SetZIndex overloads that take DependencyObject are now removed. The UIElement overloads should be used instead.
• Some obsolete members are now removed.
• BaseFragment is not needed and is now removed.
• ViewHelper.GetScreenSize method on iOS/macOS is now internal.
• FrameworkElement constructors are now protected instead of public
• ViewHelper.MainScreenScale and ViewHelper.IsRetinaDisplay are removed in iOS and macOS
• Some RelativePanel methods had UIElement parameters named as "view". This is now renamed to "element"

• PanelExtensions is now removed.
• ICoreWindowEvents is no longer public.
• FrameBufferHost and GtkHost constructors that takes args are now removed. args were already unused.
• RegisterDefaultStyleForType methods were removed.
• Xaml code generator was generating an always-null-returning FindResource method. This method is no longer generated.

• This type is hidden when programming with .NET.
• Control.GetImplementedRoutedEvents method is now removed.
• ContentPropertyAttribute.Name is now a field to match UWP.
• In UWP, IClosable appears as System.IDisposable. The interface is now removed along with Deferral.Close which was implementing the interface.

The 4th release of 2023 brings many updates to Uno Platform, including the much-requested MAUI Embedding, Lightweight Styling along with the new ShadowContainer control, Neumophic Styles, iOS Hot Restart, Wasm CSP Support and more.

Our team is aiming to make you as productive as possible developing with .NET. The community and clients asked for MAUI extensions to be developed to aid them in Xamarin.Forms migration, so we delivered. In addition we support the .NET OSS ecosystem and we regularly contribute to .NET, including the two PRs that are making MAUI embedding more effective (https://github.com/dotnet/maui/pull/16758, https://github.com/dotnet/maui/pull/16803), as well as the latest SkiaSharp 2.88.5 which includes .NET 8 compatibility and WebAssembly fixes.

See our blog post for more details!

First, .NET developers can now reuse MediaPlayerElement across all supported platforms – iOS, Android, Web, Mac and Linux, in addition to, of course, Windows itself.

Second, we’ve added support for WebView2 for iOS, Android and Mac Catalyst.

We're excited to announce our second release for 2023, which includes over 200 fixes and product improvements, as well as support for .NET 8 Preview 2.

As promised, we've been hard at work on the improvements you requested in our 2023 Roadmap survey. One of the top requests was to make the startup experience with Uno Platform as seamless as possible. In response, we've introduced a new startup experience designed to make setting up new projects with Uno Platform easier and more flexible than ever before. The Uno Platform Templates wizard will guide you through setting up your project, allowing you to choose as many or as few pieces of Uno Platform as you desire. So, starting a new Uno Platform project is easier than ever moving forward!

As with every release we also spent significant effort in improving performance across all supported platforms. In addition to multiple in-memory and runtime performance improvements we are introducing OpenGL acceleration for Uno Islands, which are typically used in WPF modernization scenarios, showing 12x improvement over software rendering. In addition, TextBlock rendering for all Skia backends, showing 5x improvements in common scenarios.

Here are some additional noteworthy improvements:

• ThemeShadow for iOS/Catalyst/Android
• Shadows on Skia targets
• Performance and memory improvements
  • Memory improvement in XAML SourceGenerator
  • Runtime performance and memory improvement in DependencyObject
  • Memory improvements in ItemsControl and ContentControl
• GTK+Linux fixes for Ubuntu 23.04+ and Arch distributions

As always, a big shoutout to everyone who worked closely with our core contributor team to make this release possible:

• Reliability fixes by @morning4coffe-dev
• Documentation updates by @morning4coffe-dev, @mrlacey
• Localization fixes by @igiona
• Build updates by @workgroupengineering
• VS Code updates by @kojo12228
• Skia Shadows support by @VitezslavImrysek
• Libinput fixes by @microhobby
• Wasm fix by @mmarinchenko

Head to our blog post for additional details on this release!

BREAKING CHANGES

• assets: The ms-appx:/// specifier for libraries introduced in Uno Platform 4.6 was incorrectly lower-casing the library name. This change now uses the original name used by the library, which is the AssemblyName property of the library hosting the assets.

Today we are announcing support for .NET 7. Our sixth release of 2022 is a huge step towards creating the most productive platform for building .NET-based applications which run everywhere.

For more about the highlights, such as core .NET 7 support, Library Assets, SVG Support, Android 13, the new WebAssembly Bootstrap 7.0 and ASP.NET Core Hosting Project, head to our blog post!

BREAKING CHANGES

• Changing Time of TimePickerFlyout from UI doesn't preserve existing days, seconds, and milliseconds. To get the legacy behavior back, set FeatureConfiguration.TimePickerFlyout.UseLegacyTimeSetting to true.

• On iOS, when running under the iOS Simulator, the MtouchExtraArgs property must include --registrar=static or the runtime will fail with the following message:

  Don't know how to marshal a return value of type 'System.IntPtr'.
  

  This validation can be disabled by setting the MSBuild property:

  <PropertyGroup>
     <UnoDisableValidateIOSStaticRegistrar>true</UnoDisableValidateIOSStaticRegistrar>
  </PropertyGroup>
  

  See https://github.com/unoplatform/uno/issues/9430 for more details.

• Native popups on Android were frequently causing problems with more complex controls like AutoSuggestBox and MenuBar. To aleviate these problems we are switching to use the unified managed popups everywhere instead. This may be breaking apps which depend on the native popups logic or layout.

• This update adjust the name of android drawables, in order to have full path disambiguation. This also means that actual resource names now will be separated by "_" in place of the folder hierarchy. This is generally not a problem is the files are read using ImageSource.
