.NET 11 Preview 3 just dropped with some great .NET MAUI improvements. In this video I walk through the highlights.

Curious about the XAML Source Generation? Have a look here: https://youtu.be/3APIPxqpzTc

Maps got a big upgrade:
- Pin clustering with ClusteringIdentifier
- Custom pin icons with ImageSource
- Custom JSON map styling
- MapLongClicked event
- Click events for circles, polygons, and polylines
- IsVisible and ZIndex on MapElements
- Programmatic info-window control

LongPressGestureRecognizer is now built in:
No more toolkit workarounds. Just add it to any view with MinimumPressDuration and a Command. Works across all platforms.

XAML and styling improvements:
- ResourceDictionary entries are now inflated on demand instead of at startup
- Implicit XAML namespace declarations enabled by default
- InvalidateStyle() and VisualStateManager.InvalidateVisualStates() for explicit reapplication during Hot Reload
- MAUI CSS is now trimmable when you don't use stylesheets

Also in this preview:
- iOS notification permission support via Permissions API
- Android 17 / API 37 preview support
- Smaller release builds (77.8 MB down to 41.6 MB on Apple platforms)
- Faster incremental builds (~39s down to ~26s)

We Are .NET

.NET MAUI Preview 3 for .NET 11 introduces several long-requested features. Maps now support pin clustering (grouping nearby pins that expand on zoom) for iOS and Android, custom pin icons via ImageSource, click handlers on map overlays (circles, polygons), and a new long press gesture on the map. A general-purpose LongPressGestureRecognizer is also added, supporting minimum press duration (iOS/macOS/Windows), state tracking (started, running, completed, canceled), position tracking, and command binding. XAML improvements include implicit namespaces (reducing boilerplate to one line) and XAML source generation (compiling XAML to C# for faster startup and consistent debug/release behavior). Developers are encouraged to test preview versions to surface bugs before the GA release in November 2026.
