Worked on enhancing accessibility and automation for Avalonia UI components hosted within WinForms, focusing on the AvaloniaUI/Avalonia repository. Addressed a UI Automation visibility issue by implementing the IRootProvider interface in EmbeddableControlRootAutomationPeer, ensuring the Avalonia automation tree is accessible to UI Automation clients when embedded via WinFormsAvaloniaControlHost. Utilized C# for development and incorporated comprehensive unit and automated UIA tests to verify correct behavior and prevent regressions. This work improved accessibility compliance and enabled more reliable automated UI testing with tools such as Inspect.exe, Narrator, and FlaUI, reducing manual testing requirements and increasing release confidence.
