* Add 7 core .NET MAUI development skills to dotnet-maui plugin Add maui-shell-navigation, maui-collectionview, maui-data-binding, maui-dependency-injection, maui-app-lifecycle, maui-safe-area, and maui-theming skills with eval.yaml tests and reference docs. Update plugin.json, marketplace.json (both copies), and CODEOWNERS. Resolves #455 Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Fix cross-skill references to non-existent skills Replace 10 dangling references to skills not in this repo (maui-deep-linking, maui-platform-invoke, maui-unit-testing, maui-maps, maui-animations, maui-accessibility, maui-app-icons-splash, maui-bootstrap-theme, maui-localization) with plain-English guidance or references to skills that exist in this PR. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Fix code correctness bugs and remaining cross-references Address PR review feedback and skeptic review findings: Code correctness: - Fix BackgroundColor="Primary" (XAML crash) → use {StaticResource Primary} - Fix MergedDictionaries.Clear() (nukes all styles) → remove-then-add pattern - Fix HorizontalStackLayout Fill (no effect) → use Grid with ColumnDefinitions - Fix AncestorType with ViewModel type → use ContentPage (visual element) - Fix Frame usage → replace with Border (recommended control) - Remove redundant MultiBinding StringFormat="{}{0}" - Fix OnStart reference → use CreateWindow for theme restore - Soften lifecycle OnStart/OnSleep characterization (compat shims, not absent) - Qualify ResourceDictionary code-behind requirement (only for x:Class) Cross-references: - Remove all remaining body-text refs to non-existent skills - Replace with Microsoft Learn doc links or generic guidance Eval: - Relax SafeAreaRegions assertion to accept SafeAreaEdges or SafeAreaRegions - Relax theming rubric for ResourceDictionary code-behind Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Restore Clear() theme pattern with clarifying comment The Clear()+Add() pattern is intentional — theme dictionaries are designed to be the only merged dictionaries in this architecture. Added comment explaining the assumption and what to do if non-theme dictionaries exist. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Fix second-pass review findings: API accuracy and eval robustness Code correctness: - ScrollView SafeAreaEdges="All" → "Container" (ScrollView only honors Container and None; All silently fails for keyboard avoidance) - DI CreateWindow example: add comment noting AppShell must be registered - AddHttpClient: add comment noting Microsoft.Extensions.Http NuGet required - MultiBinding: remove redundant StringFormat from reference doc (matches SKILL.md) - RelativeSource Self table: Path=Width → Path=WidthRequest (Width is read-only -1 before layout; WidthRequest is the correct bindable property) - CollectionView StackLayout warning: clarify it refers to BindableLayout on StackLayout vs CollectionView ItemsLayout types - SafeAreaEdges: fix "attached property" → "property" (it's a regular property) - ios:NavigationPage example: add xmlns comment for ios namespace Eval assertions: - DI Scoped regex: accept "doesn't"/"lacks"/"without" not just "no" - CollectionView ViewCell: match negation in either direction around ViewCell - Lifecycle events: require 3+ distinct events instead of any single one Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Fix final PR review comments - safe-area eval: tighten Container assertion to require SafeAreaEdges context - DI: merge #else fallback into single compilable #if block - lifecycle: behaviour → behavior (American English consistency) - theming: macOS Catalyst minimum 10.14 → 10.15 (Catalina required) Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> --------- Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

|
|
prompt: |
|
|
I have a .NET MAUI app with a ContentPage containing labels, buttons, and
|
|
a background color. Everything is hardcoded to light colors right now.
|
|
I want the app to automatically switch between light and dark mode based
|
|
on the device's system theme. Show me how to use AppThemeBinding to make
|
|
this page theme-aware in XAML and explain the C# alternative.

prompt: |

I need to support three branded themes in my .NET MAUI app — a light theme,
|
|
a dark theme, and a high-contrast theme. Users should be able to pick their
|
|
preferred theme from a settings page and it should apply immediately across
|
|
the app. How do I set this up?

prompt: |

My .NET MAUI app needs to detect when the user toggles dark mode in their
|
|
device settings and respond in real time — both updating the UI and logging
|
|
the change. How do I detect the current system theme and subscribe to
|
|
theme change events? Also, how do I let the user force a specific theme
|
|
regardless of system setting?

prompt: |
|
|
I'm adding dark mode to my .NET MAUI Android app. I created ResourceDictionary
|
|
themes and used StaticResource to bind colors in my XAML pages. When I
|
|
switch themes at runtime nothing changes — the colors stay the same. Also,
|
|
when the user toggles dark mode in Android settings my app seems to restart
|
|
completely. What am I doing wrong?
