Inspect existing `Resources`, `ResourceDictionary`, `App.xaml`, and platform\n   language declarations.\n2. Put user-visible strings in RESX resources or the app's existing localization\n   service.\n3. Use culture-aware formatting for dates, numbers, and currency.\n4. If runtime language switching is required, centralize culture updates and\n   notify UI bindings.\n5. Add RTL support through `FlowDirection` and test with an RTL culture.\n6. Define colors, spacing, and styles as resources.\n7. Use `AppThemeBinding` for simple light\u002Fdark values and `DynamicResource` for\n   values that change at runtime.\n8. Set `Application.Current.UserAppTheme` only when the user explicitly chooses\n   a theme; use `Unspecified` for system theme.\n\n## RESX Pattern\n\nUse a default resource file plus culture-specific files:\n\n```text\nResources\u002FStrings\u002FAppResources.resx\nResources\u002FStrings\u002FAppResources.es.resx\nResources\u002FStrings\u002FAppResources.fr.resx\n```\n\nReference generated resources from XAML or ViewModels instead of hard-coded\nstrings. Keep resource keys stable and descriptive.\n\n## Runtime Culture Switching\n\nWhen the user changes language:\n\n- Set `CultureInfo.DefaultThreadCurrentCulture`.\n- Set `CultureInfo.DefaultThreadCurrentUICulture`.\n- Update any generated resource culture property if the app uses one.\n- Notify bound localized strings, recreate affected pages, or use a localization\n  manager that raises change notifications.\n- Persist the selected culture in `Preferences` only after the user chooses it.\n\nDo not assume changing the thread culture automatically refreshes every existing\nbinding. Existing pages usually need notification or recreation.\n\n## Platform Language Declarations\n\n| Platform | Check |\n| --- | --- |\n| iOS\u002FMac Catalyst | Include supported localizations such as `CFBundleLocalizations` when platform language metadata is required. |\n| Android | Confirm app language\u002Fresource configuration if using platform-specific localized resources. |\n| Windows | Confirm package\u002Fresource language metadata if the app has Windows-specific resources. |\n\n## RTL Guidance\n\n- Use `FlowDirection=\"MatchParent\"` for most pages and layouts.\n- Set `FlowDirection=\"RightToLeft\"` only when forcing a specific surface.\n- Avoid left\u002Fright naming in resources; prefer start\u002Fend semantics in code and\n  design tokens.\n- Verify icons and gestures that imply direction.\n\n## Theme Patterns\n\n```xml\n\u003CContentPage BackgroundColor=\"{AppThemeBinding Light=#FFFFFF, Dark=#111111}\" \u002F>\n\n\u003CLabel TextColor=\"{DynamicResource PrimaryTextColor}\" \u002F>\n```\n\nRuntime theme changes should update resource dictionaries or\n`Application.Current.UserAppTheme`:\n\n```csharp\nApplication.Current!.UserAppTheme = AppTheme.Dark;\n```\n\nUse `DynamicResource` for resources that must react after the page is created.\nUse `StaticResource` only when values are not expected to change at runtime.\n\n## Validation Checklist\n\n- User-visible strings are resource-backed.\n- Culture changes update existing UI or intentionally recreate affected pages.\n- RTL cultures have been considered for layout direction and icons.\n- Theme resources use `AppThemeBinding` or `DynamicResource` appropriately.\n- User theme selection can return to system default.\n",{"data":49,"body":50},{"name":4,"description":6},{"type":51,"children":52},"root",[53,62,68,75,184,190,195,207,212,218,223,273,278,284,359,365,402,408,447,459,475,494,500,542],{"type":54,"tag":55,"props":56,"children":58},"element","h1",{"id":57},"maui-localization-and-theming",[59],{"type":60,"value":61},"text","MAUI Localization and Theming",{"type":54,"tag":63,"props":64,"children":65},"p",{},[66],{"type":60,"value":67},"Use this skill when a MAUI app needs translated strings, culture-specific\nformatting, right-to-left support, or runtime theme changes.",{"type":54,"tag":69,"props":70,"children":72},"h2",{"id":71},"workflow",[73],{"type":60,"value":74},"Workflow",{"type":54,"tag":76,"props":77,"children":78},"ol",{},[79,109,114,119,124,137,142,163],{"type":54,"tag":80,"props":81,"children":82},"li",{},[83,85,92,94,100,101,107],{"type":60,"value":84},"Inspect existing ",{"type":54,"tag":86,"props":87,"children":89},"code",{"className":88},[],[90],{"type":60,"value":91},"Resources",{"type":60,"value":93},", ",{"type":54,"tag":86,"props":95,"children":97},{"className":96},[],[98],{"type":60,"value":99},"ResourceDictionary",{"type":60,"value":93},{"type":54,"tag":86,"props":102,"children":104},{"className":103},[],[105],{"type":60,"value":106},"App.xaml",{"type":60,"value":108},", and platform\nlanguage declarations.",{"type":54,"tag":80,"props":110,"children":111},{},[112],{"type":60,"value":113},"Put user-visible strings in RESX resources or the app's existing localization\nservice.",{"type":54,"tag":80,"props":115,"children":116},{},[117],{"type":60,"value":118},"Use culture-aware formatting for dates, numbers, and currency.",{"type":54,"tag":80,"props":120,"children":121},{},[122],{"type":60,"value":123},"If runtime language switching is required, centralize culture updates and\nnotify UI bindings.",{"type":54,"tag":80,"props":125,"children":126},{},[127,129,135],{"type":60,"value":128},"Add RTL support through ",{"type":54,"tag":86,"props":130,"children":132},{"className":131},[],[133],{"type":60,"value":134},"FlowDirection",{"type":60,"value":136}," and test with an RTL culture.",{"type":54,"tag":80,"props":138,"children":139},{},[140],{"type":60,"value":141},"Define colors, spacing, and styles as resources.",{"type":54,"tag":80,"props":143,"children":144},{},[145,147,153,155,161],{"type":60,"value":146},"Use ",{"type":54,"tag":86,"props":148,"children":150},{"className":149},[],[151],{"type":60,"value":152},"AppThemeBinding",{"type":60,"value":154}," for simple light\u002Fdark values and ",{"type":54,"tag":86,"props":156,"children":158},{"className":157},[],[159],{"type":60,"value":160},"DynamicResource",{"type":60,"value":162}," for\nvalues that change at runtime.",{"type":54,"tag":80,"props":164,"children":165},{},[166,168,174,176,182],{"type":60,"value":167},"Set ",{"type":54,"tag":86,"props":169,"children":171},{"className":170},[],[172],{"type":60,"value":173},"Application.Current.UserAppTheme",{"type":60,"value":175}," only when the user explicitly chooses\na theme;
