.NET MAUI 11 Preview Samples

Sample app that separates the new .NET MAUI 11 Preview 4 additions from the .NET MAUI 11 Preview 3 samples that are still included for comparison.

For the previous walkthrough, check out the video: What's New in .NET MAUI 11 Preview 3

Features

Preview 4 additions

• Shell and ToolbarItem badges — BadgeText, BadgeColor, and BadgeTextColor on Shell tabs and primary toolbar items
• CoreCLR runtime default — Preview 4 uses CoreCLR by default for .NET MAUI targets
• Material 3 Android controls — sample ImageButton, DatePicker, Entry, and Slider controls that pick up the expanded Material 3 handlers on Android
• x:Code directive — inline C# event handler declared directly in XAML
• Compiled bindings in DataTemplates — strongly typed CollectionView template with x:DataType
• dotnet watch for Android and iOS — project settings include the iOS simulator MtouchLink=None workaround from the Preview 4 release notes
• Android themed icons — MauiIcon now declares a dedicated MonochromeFile layer

Preview 3 samples

Maps

• Pin clustering — group nearby pins automatically with IsClusteringEnabled and ClusteringIdentifier
• Custom pin icons — use any image as a pin marker via Pin.ImageSource
• Long press to drop pins — MapLongClicked event for adding pins interactively
• Overlay click events — CircleClicked and PolygonClicked on map elements
• Overlay visibility — toggle overlays with MapElement.IsVisible

LongPressGestureRecognizer

• Built-in long press — first-party LongPressGestureRecognizer with configurable MinimumPressDuration
• State tracking — LongPressing event with GestureStatus for real-time feedback
• Position tracking — GetPosition() to get touch coordinates relative to any element

XAML Improvements

• Implicit namespaces — no more xmlns= boilerplate; standard MAUI and x: namespaces are implicit in .NET 11
• Source generation by default — XAML source gen is now on for all pages with lazy resource loading
• New style APIs — InvalidateStyle() and VisualStateManager.InvalidateVisualStates() for runtime style mutations

Prerequisites

• .NET 11 Preview 4 SDK
• .NET MAUI workload: dotnet workload install maui
• Xcode 26.4+ (iOS/macOS)
