2.2

The Uno 2.2 release is packed with new features, performance improvements and bug fixes, even if it's closely following the 2.1 release!

We're also hard at work on adding support for macOS apps (Thanks @MartinZikmund), and while we still do not have anything to announce, it's taking shape!

Among the implemented features, you'll find:

• Support for MenuFlyout, UIElement.ContextFlyout and MenuBar
• Support for ScrollBar
• Add support for dotnet new unoapp and macOS templates
• Support for Electron hosted apps
• ImageSource.SetSourceAsync support for WebAssembly (Thanks @SuperJMN)
• Support for ColorAnimation
• Support for Pedometer for iOS and Android (Thanks @MartinZikmund)
• Suppport for mouse wheel events (PointerWheelChanged) on WebAssembly
• Support for DropDownButton from WinUI 2 (Thanks @MartinZikmund)
• Many performance and memory updates impacting all platforms at various levels, such as giving a rough 20% improvement on controls creation on WebAssembly. A more detailed post will follow soon on that topic.
• Support for ms-appdata paths in Image, MediaPlayer (Thanks @MartinZikmund)

Uno is now built using C# 8.0 and VS 16.5 on Azure Devops hosted agents, which means that AndroidX and Android 10 support is close by.

And finally, many of the recent updates were targeted at improving the behavior of controls in the Windows Community Toolkit, with enabling DataGrid, TabView and Expander controls. On the topic of the DataGrid, there's still lots of work to be done, particularly around performance under WebAssembly, but this release updates now make the control useable.

2.1

Uno Platform 2.1 release is packed with over 50 new features allowing for increased productivity as well as getting you up and running with Surface Duo. In addition to bigger milestones such as x:Bind, the TwoPaneView and NumberBox controls we also shipped another 50 new features and closed 45 issues you raised.

Among many other updates:

2.0.528

This release is bits that were announced at UnoConf in September, and it's a big one! It contains lots of new features, improvements, and bug fixes.

This release is now a community effort, thanks to Hacktoberfest, an also to community contributors such as @MartinZikmund, @pkar70, @kakone, @pdecostervgls, @gevart and all the Uno Team people!

Note: To install the latest Visual Studio Extension to use XAML Hot Reload, you'll need to do it from the release files below for the next few days, as the release there is still 1.45. We're discussing publication issues with the Microsoft VS Marketplace team about that, we'll update the release notes accordingly. The VSIX is now updated in the marketplace!

XAML Hot Reload for iOS, Android and WebAssembly

XAML Hot Reload is now supported, giving ability to design the UI of a running application directly from Visual Studio. Best of all, it can update multiple platforms at once!

Head to this guide to get started.

Dark mode support

ThemeResources support to enable Dark Theme has been included, with automatic detection on iOS, Android and WebAssembly. It's not yet supporting live update from one theme to another, but this is coming soon!

You can view the results of this support in the Uno Calculator (WebAssembly, App Store and Play Store), in the Xaml Controls Gallery WebAssembly App, and the Windows Communit Toolkit WebAssembly App.

Pointer and Manipulation events

This release adds extensive support for Pointer events and Manipulation events, paving the way for more advanced controls support such as data grids, and other interactive controls.

GitPod WebAssembly development support

GitPod enables very interesting scenarios for friction-less development with Uno, as well as contributing to Uno. Because there is nothing to install, and that everything runs in your browser, it lowers the barrier to entry for developing, as there's no step of "setting up the environment" that can take such a long time on some cases.

GitPod also enables live PR validations, with the pre-build features, allowing to test the live bits of a PR inside of a running VS Code instance, simply by clicking on the "review in GitPod" button in every PR.

Get started [here with this guide].(https://github.com/unoplatform/uno/blob/master/doc/articles/features/working-with-gitpod.md).

Visual Studio 4 Mac compatibility for iOS and Android

Building an app for iOS and Android in Visual Studio for mac is now supported, with initial support for XAML intellisense, in release 8.4.

Uno Platform WebAssembly Renderers for Xamarin.Forms

This release also enables the support for WebAssembly Renderers for Xamarin Forms 4.3.

Other additions

• Large improvements in UIElement clipping behavior
• Support for hardware APIs such as Windows.Devices.Lights.Lamp, Geolocator, Gyrometer, Magnetometer, Accelerometer, VibrationDevice, Barometer
• Support for system apis JumpList, PhoneCallManager, DisplayInformation
• PathGeometry and PolyLine support for WebAssembly
• XAML type conversions through CreateFromStringAttribute
• Support for ContentDialog, PersonPicture, TooltipService, ToggleButton.IsThreeState and TextBox.IsReadonly (WebAssembly)
• VisualState setters support for static, theme resources and template bound values

Lots of work has been done to make Uno more reliable, with the inclusion of UI and on-device unit testing for iOS, Android and WebAssembly as part of the PR process. Each PR is now validated by running an extensive set of tests through the uno.uitest cross-platform UI Testing library.

This release also includes updates that enable support for ReactiveUI (samples) and VLC

Here's the full list:

Features

• #2029 Support for MenuFlyoutItem.Click

• Add support for Windows.Phone.Devices.Notification.VibrationDevice API on iOS, Android and WASM
• Basic support for Windows.Devices.Sensors.Barometer

• [Wasm] Add support for DisplayInformation properties LogicalDpi, ResolutionScale, ScreenWidthInRawPixels, RawPixelsPerViewPixel , and ScreenHeightInRawPixels¸
• Permit DependencyProperty to be set reentrantly. E.g. this permits TextBox.TextChanged to modify the Text property (previously this could only be achieved using Dispatcher.RunAsync()).
• Add support for filtered solutions development for Uno.UI contributions.
• 132984 [Android] Notch support on Android
• Add support for Android UI Tests in PRs for improved regression testing
• Add static support for ThemeResources: Application.Current.RequestedTheme is supported
  • Dark and Light are supported.

    (this is a feature not supported in UWP)

    // Put that somewhere during app initialization...
    Uno.UI.ApplicationHelper.RequestedCustomTheme = "MyCustomTheme";

  • FrameworkElement.RequestedTheme is ignored for now.
  • Should be set when the application is starting (before first request to a static resource).
• Prevent possible crash with MediaPlayerElement (tentative)
• Add support for ContentDialog, including Closing and Closed events
• Permit DependencyProperty to be set reentrantly. E.g. this permits TextBox.TextChanging to modify the Text property (previously this could only be achieved using Dispatcher.RunAsync()).
• Implement TextBox.TextChanging and TextBox.BeforeTextChanging. As on UWP, this allows the text to be intercepted and modified before the UI is updated. Previously on Android using the TextChanged event would lead to laggy response and dropped characters when typing rapidly; this is no longer the case with TextChanging.
• [WASM] ComboBox's dropdown list (CarouselPanel) is now virtualized (#1012)
• Improve Screenshot comparer tool, CI test results now contain Screenshots compare data
• Updated Xamarin.GooglePlayServices.* packages to 60.1142.1 for Target MonoAndroid80

  FeatureConfiguration.ContentPresenter.UseImplicitContentFromTemplatedParent = false;
  

• Add support for Selector.IsSynchronizedWithCurrentItem
• Add support for CoreApplication.MainView and CoreApplication.Views
• Add support for resolution of merged and theme resources from ResourceDictionary in code
• Add non-failing StatusBar BackgroundOpacity and BackgroundColor getters
• Relax DependencyProperty owner validation for non-FrameworkElement
• ToolTip & ToolTipService are now implemented...
