Fantastic work to end off the year on a 2.0 release, would be great to clear the completed milestones for 2026 https://github.com/microsoft/WindowsAppSDK/milestones?sort=completeness&direction=desc

Those fancy new features are unusable because its foundation is currently broken with many bugs and luck of basic features.
