.NET MAUI 11 Preview 4 introduces several notable features. The biggest runtime change is the switch to CoreCLR by default, replacing Mono and unlocking standard .NET debugging and profiling tools. Long-requested badge support is now available for toolbar items and tab bar items, with configurable badge text, color, and text color via simple XAML properties. Inline C# code in XAML (Xcode directive) is now supported, allowing event handlers to be written directly in XAML. Other additions include compiled bindings inside data templates for build-time binding checks and IntelliSense support, .NET watch support for Android and iOS hot reload from the terminal, monochrome file support for Android adaptive icons, and continued Material 3 control updates.
