Inspect a running WinUI 3 app's XAML with winapp devtools: resolved property values (margin, size, style), what a binding yields or why it's empty, the XAML line behind an element, live edits, and UI review comments left in the app. To click, type, read text or screenshot, use winapp-ui-automation.
