Adding another ring to my Microsoft MVP award stand 🎉 . It has been a turbulent year and this renewal was definitely not a given, which makes it that much more valuable in my mind. Everything is changing fast, but I'm still looking forward to more learning and sharing #MVPBuzz

🎬 Coming to @platform.uno: AnimatedIcon from WinUI! It takes animated visuals generated by LottieGen and renders them in place of regular icons, allowing playful visual state transitions - super fun to play with! #winui #appdev

This one's been on my backlog forever and finally shipped it. RequestedTheme now works on any element in the visual tree in @platform.uno. Set light or dark theme on any element, nest them, switch at runtime

It may not seem like much, but I've been trying to get this green checkmark for SO long. All @platform.uno runtime tests will also run in CI against WinAppSDK meaning we'll automatically catch any test that has incorrect assumptions 🎉 #dotnet #opensource

Just merged PlaneProjection & Matrix3DProjection API support for @platform.uno! 🚀 3D perspective transforms on any UI element - card flips, tilts, carousels - working across iOS, Android, macOS, Windows, Linux & WebAssembly. This one was fun to build! #dotnet #csharp #xaml #winui

When I ported DOOM to @platform.uno #WebAssembly, I noticed that running and shooting can easily close the tab (Ctrl + W combo). Luckily there is Keyboard.lock/unlock API that can block browser shortcuts for full screen apps - coming soon as a easy-to-use #csharp API!
