Microsoft announced .NET Multi-platform App UI (MAUI) Preview 9 release.

Much of the work in this preview is focused on completing and stabilizing the 50+ controls and layouts, but the major updates were done to support for borders, corners, and shadows across most all controls and layouts. Also it should be mentioned that Microsoft made a lot to improve Android apps start instantly.
