Is it possible to use CSS for dynamic theme switching?

No, while MAUI supports CSS styling, those styles cannot be swapped dynamically at runtime. Use ResourceDictionaries for theme-switching functionality.

How do I handle Android theme changes without crashing?

You must include ConfigChanges.UiMode in your MainActivity's Activity attribute to ensure the OS handles theme changes correctly without restarting the activity.

Can I swap themes at runtime in .NET MAUI?

Yes, by swapping ResourceDictionaries in the MergedDictionaries collection and ensuring all UI elements use DynamicResource instead of StaticResource.

What is the difference between StaticResource and DynamicResource for themes?

DynamicResource allows UI elements to update their appearance immediately when the underlying resource changes at runtime, whereas StaticResource only looks up the value once during initial load.
