unoplatform/uno 4.0.7

on GitHub

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.

BREAKING CHANGES

• This change is a binary breaking change only.
• android: Move Uno.UI.DualScreen to Uno.UI.Foldable
• • Removal of Uno.Extensions.ObservableCollectionUpdateResultsExtensions

• Removal of UIAsyncOperation.CompletionSource
• Changed type of ApiInformation.NotImplementedLogLevel to Uno.Foundation.Logging.LogLevel

This change also moves to use the up-lifted Input APIs provided by the Microsoft.UI.Input namespace.

• 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.
• Align FlyoutBase.Opened, FlyoutBase.Closed, and FlyoutBase.Opening signature with UWP.
• Source paths starting with '/' are now considered relative to project root instead of current file.
• Introduces a breaking change for InputScope that is controlled by FeatureConfiguration.TextBox.UseLegacyInputScope
