Fix: launchSettings.json environment variables are ignored for a commandName: Executable profile

2026-09-29 errors dotnet dotnet-10

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.

2026-09-28 errors dotnet dotnet-10

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.

MAUI 10.0.101 and 10.0.110 Resizetizer ship mismatched System.Memory references, so SVGs with filters or text fail. Pin Resizetizer 10.0.100 or strip the filter and text.

2026-09-27 errors dotnet dotnet-10

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.
