ShadUI 0.2.4 updates the library to Avalonia 12.1.0 and improves control behavior, lifecycle cleanup, and animation reliability across the library and demo app.

Important

.NET 8 support has been removed. Applications consuming this release must target .NET 9 or later. Projects that still require .NET 8 should remain on ShadUI 0.2.3 until they can upgrade.

Requirements

  • Supported target frameworks: net9.0 and net10.0
  • Avalonia updated to 12.1.0

Control fixes and improvements

  • Sidebar
    • Reliably remembers and restores its expanded width across collapse/expand cycles.
    • Handles rapid state changes, template reapplication, and visual-tree attachment without stale animations or one-frame width jumps.
    • Cancels superseded transitions cleanly and preserves the correct opacity when MinWidth is zero.
  • NumericUpDown
    • Restores increment/decrement using the Up and Down arrow keys.
    • Restores mouse-wheel spinning while the control has keyboard focus.
    • Prevents the parent smooth-scrolling container from intercepting wheel input intended for the spinner.
  • TabControl
    • Uses a constrained grid layout so selected content can contain an internal ScrollViewer correctly.
    • Restores the animated selection indicator by applying the tab background through the template.
    • Adds regression coverage for the complete tab-header hit target.
  • Window
    • Adds ShowAvaloniaFullscreenPopover, defaulting to false, to suppress Avalonia's built-in fullscreen exit affordance when ShadUI chrome is used. Set it to true to opt back in.
    • Preserves the correct Windows maximized inset without overriding the normal root margin.
  • Menu
    • Corrects popup ancestor bindings for menu and submenu overlay input pass-through behavior.
  • ColorPicker
    • Keeps the color swatch and hexadecimal preview text synchronized when Color changes, including when the picker is hosted inside a dialog.
  • Toast
    • Fixes bulk dismissal so every queued toast is removed correctly.
    • Restores existing queued toasts when a host attaches or changes managers.

Performance and reliability

  • Demo pages are now created lazily on first navigation instead of all being instantiated at startup.
  • Page, dashboard, code-snippet, and navigation resources are released cleanly when the demo closes.
  • Dialog and toast hosts now subscribe only while attached to the visual tree and detach manager/template handlers during cleanup, reducing duplicate callbacks and retained controls.
  • Attached-property behaviors, scroll handlers, sidebar items, dialogs, and toasts now clean up event subscriptions more consistently.
  • Sidebar, dialog, and toast transitions cancel superseded work safely; background animation failures are observed instead of becoming unhandled task exceptions.

Tests

Added regression coverage for:

  • Sidebar width restoration
  • NumericUpDown keyboard and wheel spinning
  • ColorPicker previews inside dialogs
  • Tab header hit targets
  • Dialog and toast manager subscription lifecycles
