How do I force a specific theme regardless of system settings?

The skill provides code references for setting the UserAppTheme property in C#, allowing you to override the OS preference with a specific user-selected theme.

Does this skill support CSS-based theming in .NET MAUI?

The skill clarifies that while MAUI supports CSS, those styles cannot be swapped at runtime; it recommends using ResourceDictionaries for dynamic switching instead.

Can I use this skill to switch between more than two themes?

Yes, it guides you through ResourceDictionary swapping, which supports multiple custom branded themes beyond just standard light and dark modes.

How does this skill help with Android theme changes?

It provides the specific ConfigChanges.UiMode requirements for the MainActivity to ensure theme events fire correctly without restarting the application.

Why should I use DynamicResource instead of StaticResource for theming?

DynamicResource allows the UI to update automatically at runtime when the theme dictionary changes, whereas StaticResource only evaluates the value once during initial load.
