.NET MAUI App Theming FAQs

Question 1

Can I use this skill to implement custom themes beyond just light and dark mode?

Accepted Answer

Yes, this skill provides specific guidance on using ResourceDictionary swapping to support multiple custom branded themes beyond the standard OS light and dark settings.

Question 2

Why does my Android app restart when the theme changes?

Accepted Answer

This is typically caused by a missing ConfigChanges.UiMode attribute in your MainActivity. This skill provides the exact boilerplate needed to handle theme changes without a restart.

Question 3

Should I use StaticResource or DynamicResource for my theme colors?

Accepted Answer

For runtime theme switching to work, you must use DynamicResource. StaticResource only evaluates once at load time, while DynamicResource allows the UI to update when the theme dictionary is swapped.

Question 4

Does this skill help with CSS-based styling in MAUI?

Accepted Answer

The skill acknowledges CSS support but recommends ResourceDictionaries for theming because CSS-based themes cannot be swapped dynamically at runtime in .NET MAUI.

Question 5

How do I programmatically force the app into a specific theme?

Accepted Answer

The skill guides you on using Application.Current.UserAppTheme to override the system default, allowing you to set the app to AppTheme.Dark or AppTheme.Light regardless of OS settings.
