How do I prevent Android apps from restarting when the theme changes?

You must include 'ConfigChanges.UiMode' in your MainActivity's ConfigurationChanges attribute. This allows the app to handle the theme change event without restarting the activity.

When should I use DynamicResource instead of StaticResource?

Use DynamicResource whenever a value in a ResourceDictionary might change at runtime, such as when swapping themes. StaticResource only evaluates the value once at load time.

Can I use CSS for dynamic theme switching in .NET MAUI?

While .NET MAUI supports CSS for styling, CSS-based themes cannot be swapped dynamically at runtime. For dynamic switching, ResourceDictionaries are the recommended approach.

How do I manually force the app to stay in Dark Mode?

You can override the system theme by setting 'Application.Current.UserAppTheme = AppTheme.Dark' in your application logic.

Implements professional light and dark mode support, dynamic resource management, and custom theme switching for .NET MAUI applications.

The maui-theming skill provides comprehensive guidance for managing visual styles and user preferences in .NET MAUI apps. It covers critical implementation patterns including AppThemeBinding for automatic system-level theme response and ResourceDictionary swapping for multi-theme branded experiences. This skill helps developers avoid common pitfalls, such as Android activity restarts during UI mode changes, and ensures that UI elements update correctly at runtime by enforcing the proper use of DynamicResources over StaticResources.
