MAUI 10.0.110 ships six leak fixes for BackButtonBehavior, SwipeItemView, ListView.RefreshCommand, IndicatorView, GeometryGroup and TableView. Most were filed and patched by gh-aw workflows, and they matter most if you use RelayCommand from CommunityToolkit.Mvvm.

Fix: Android status bar icons become unreadable after enabling UseMaterial3 in .NET MAUI 10

MAUI 10.0.100 picks status bar icon colors from colorPrimary, which is the opposite brightness of the Material 3 surface, so you get white on white or black on black. Update Microsoft.Maui.Controls to 10.0.101 or later, or reset AppearanceLightStatusBars in MainActivity.

Fix: .NET MAUI Entry with Keyboard.Numeric shows a small numpad, then the full keyboard, on iPadOS 26

On iPadOS 26, MAUI maps Keyboard.Numeric to UIKeyboardType.DecimalPad, which now opens as a floating mini numpad. Append a mapper that switches iPad to NumbersAndPunctuation and filter input yourself.

Fix: MediaPicker.CapturePhotoAsync returns a PNG instead of a JPEG in .NET MAUI 10

On iOS, MAUI 10 re-encodes camera photos as PNG whenever CompressionQuality is 90 or higher and no MaximumWidth/Height is set, which includes the default. Set CompressionQuality to 89 or lower, or add a MaximumWidth on iOS only.

Fix: UIKitThreadAccessException from MediaPicker.PickPhotosAsync when selecting multiple photos in .NET MAUI iOS

Picking 2 or more photos on iOS throws UIKitThreadAccessException in MAUI 10.0.100 and 10.0.101. MAUI reads PHPickerResult.ItemProvider after an await, off the main thread. Pin 10.0.90, upgrade to 10.0.110, or use a PHPicker shim.

How to find the async void handlers causing ANRs in a .NET MAUI Android app

Play Console tells you your ANR rate is over 0.47% and hands you a native stack full of libcoreclr.so frames. Here is how to get from that useless trace to the exact async void event handler that blocked the main thread, using a Looper printer, a SynchronizationContext wrapper that names the state machine, and dotnet-trace over dsrouter.

Migrate a .NET MAUI Android app to target Android API level 36

Google Play required target API 36 from 2026-08-31, with extensions running to 2026-11-01. Here is the full .NET MAUI path from net9.0-android to API 36: the target framework bump, the hardcoded uses-sdk that silently pins you to the old level, edge-to-edge with no opt-out, predictive back, and the large-screen orientation rules.

iOS builds set DynamicCodeSupport=false, so EF Core refuses to build the model even though you never enabled NativeAOT. Ship a compiled model plus precompiled queries, or turn the interpreter back on.
