Description of Change

This pull request adds support for Material 3 styling for the Switch control on Android in .NET MAUI. It introduces a new Material 3 switch handler, configures runtime feature toggling for Material 3, and adds the necessary Android resources and theming infrastructure for Material 3 support.

Material 3 Switch support and theming:

Introduced a new SwitchHandler2 for Android, which uses the Material 3 MaterialSwitch when the Material 3 feature is enabled. This handler includes property mapping for IsOn, TrackColor, and ThumbColor.
Updated SwitchExtensions to support updating properties (IsOn, TrackColor, ThumbColor) on both traditional and Material 3 switches. (src/Core/src/Platform/Android/SwitchExtensions.cs) [1] [2]

Handler registration logic:

Updated handler registration to use SwitchHandler2 for Switch controls on Android when Material 3 is enabled, otherwise falling back to the default handler. (src/Controls/src/Core/Hosting/AppHostBuilderExtensions.cs) [1] [2]

These changes collectively enable opt-in Material 3 switch styling on Android, controlled by a feature flag, and lay the groundwork for broader Material 3 support in .NET MAUI.

Pull request overview

This PR implements Material 3 support for the Switch control on Android in .NET MAUI. The implementation is controlled by a runtime feature flag (IsMaterial3Enabled) that defaults to false, allowing developers to opt-in via the UseMaterial3 MSBuild property. When enabled, Switch controls use the new Material 3 styling with the Material Design 3 components library.

Key Changes

Added runtime feature flag IsMaterial3Enabled with MSBuild property binding for opt-in Material 3 support
Implemented MaterialSwitchHandler and MauiMaterialSwitch to provide Material 3 switch functionality on Android
Extended SwitchExtensions with Material 3-specific property update methods for theme-aware color management
Added comprehensive Material 3 color tokens and style definitions for Android resources

PR #33132 Code Review Summary

Title: [Android] Implemented Material3 Support for Switch Control

Overall Assessment

✅ Well-structured implementation following MAUI patterns, but has critical bugs and unrelated changes that need addressing.

Critical Issues

🔴 Static field collision bug - _defaultTrackTintList and _defaultThumbTintList in SwitchExtensions are shared globally. This will cause incorrect theming when an app uses both Material 2 and Material 3 switches.
Redundant logic - UpdateThumbColor has unnecessary checks (already validated by outer if)

Medium Issues

Missing test coverage - No UI tests for MaterialSwitchHandler
Unclear #if NET10_0_OR_GREATER directive - May be unnecessary on main branch
Unrelated eng/ infrastructure changes - Build system files from merge
Deleted README.md - Unrelated deletion

Minor Issues

Missing XML documentation on MauiMaterialSwitch
Extra blank line

Recommendations

Must fix:

Fix static field collision (separate defaults per switch type)
Remove redundant checks in UpdateThumbColor
Remove unrelated changes (eng/, README.md)

Should add:

UI tests for Material 3 switch
Tests for mixed Material 2/3 usage
XML documentation

Issue: #33131 - Implement Material3 Support for Switch Control
PR: #33132 - [Android] Implemented Material3 Support for Switch Control
Author: NirmalKumarYuvaraj (community contributor, partner/syncfusion)
Platforms Affected: Android only
Files Changed: 5 implementation files, 1 test file, 6 snapshot images

Key Findings

New feature PR adding Material 3 switch support for Android when UseMaterial3 MSBuild property (or IsMaterial3Enabled runtime feature flag) is enabled
Opt-in via feature flag — RuntimeFeature.IsMaterial3Enabled (default: false), read from AppContext.TryGetSwitch
Handler architecture: New internal SwitchHandler2 class extends SwitchHandler, overrides CreatePlatformView() to return MaterialSwitch wrapped in MauiMaterialContextThemeWrapper
Registration: AppHostBuilderExtensions.cs now conditionally registers SwitchHandler2 when in the #if __ANDROID__ Material3 branch, alongside other M3 controls (Picker, RadioButton, TimePicker)
SwitchExtensions.cs extended with MSwitch-targeted overloads for UpdateIsOn, UpdateTrackColor, UpdateThumbColor — uses ConditionalWeakTable<MSwitch, ColorStateList> to cache original theme tints per-instance (thread-safe via GetValue)
SwitchHandler.Android.cs refactored: CheckedChangeListener now uses WeakReference<SwitchHandler> and is sealed — fixes potential memory leak (unrelated to M3 feature but included in PR)
Tests: Material3SwitchFeatureTests (Android-only #if ANDROID) with _GalleryUITest base, 6 screenshot tests using UITestCategories.Material3; 6 PNG baseline snapshots added to snapshots/android-notch-36/

Previous Agent Review Found

A prior agent review (multi-model: Sonnet 4.5 / GPT 5.1 / Gemini 3 Pro) identified issues, some of which have been addressed:

✅ FIXED: Race condition in ConditionalWeakTable caching (TryGetValue+Add → GetValue with factory delegate)
✅ FIXED: Redundant thumbColor is null check and materialSwitch is MauiMaterialSwitch type check removed
❓ Contested: Missing OnColor mapping in SwitchHandler2.Mapper — PR author claims ISwitch doesn't expose OnColor (TrackColor is used for on/off)
❓ Still open: RuntimeFeature.IsMaterial3Enabled not cached (uses AppContext.TryGetSwitch on every call)

Remaining Concerns

RuntimeFeature.IsMaterial3Enabled not cached — Unlike IsHybridWebViewSupported and IsMeterSupported which use static readonly fields, IsMaterial3Enabled is computed on every call. Called in MauiMaterialContextThemeWrapper constructor for each M3 control.
using System; added to SwitchHandler.Android.cs — This triggers Android.Nfc.CardEmulators reference (already there), but System should not need to be explicitly added.
Handler registration for non-ANDROID builds — #else branch (non-Android) and the shared #endif section both explicitly register SwitchHandler which was removed from the original global position. This is a restructure of the Switch registration.
Missing ThumbColor property in AppHostBuilderExtensions base SwitchHandler path — Actually this looks correct, the original SwitchHandler is now within the conditional block.
Test relies on _GalleryUITest — Tests navigate to "Switch Feature Matrix" gallery page, which may need special app configuration (Material3 enabled) to show MaterialSwitch instead of SwitchCompat.

🚦 Gate — Test Verification

Gate Result: ⚠️ INCONCLUSIVE (Environment/Configuration Issue)

Platform: Android
Mode: Full Verification

Tests FAIL without fix: ✅ (as expected — M3 baselines don't match M2 screenshot)
Tests PASS with fix: ❌ (ALSO FAIL — environmental/configuration issue)

Root Cause Analysis

The gate ran two test passes:

Without fix (revert fix files to merge-base): Build succeeded, but test execution produced no results — tests appear to time out or fail to connect via Appium. The "FAIL" was recorded because the test process exited non-zero.
With fix (restore fix from HEAD): Same behavior — build succeeded, app installed (Broadcasting Intent broadcast logged), but no Appium test output was captured.

Why Both Runs "Fail"

These are screenshot-based UI tests (VerifyScreenshot) that:

Require an active Appium connection to an Android emulator
Compare screenshots against stored PNG baselines in snapshots/android-notch-36/
Crucially require RuntimeFeature.IsMaterial3Enabled = true at runtime to activate SwitchHandler2

The IsMaterial3Enabled feature flag defaults to false. Even with the PR's fix applied, unless the test host app is launched with AppContext.SetSwitch("Microsoft.Maui.IsMaterial3Enabled", true), the M2 handler (SwitchHandler) is used — so screenshots would show a Material2 switch, not matching the M3 baselines.

The test infrastructure (BuildAndRunHostApp.ps1) does not set this flag, causing tests to fail in both configurations.

Conclusion

Tests DO exist ✅
Tests DO detect the bug (M3 baselines show M3 switch; without M3 enabled, M2 renders) ✅
Tests CANNOT be verified in this environment without special M3 configuration ⚠️
Gate marked as INCONCLUSIVE due to environment limitation

Proceeding to Try-Fix per "never stop, continue" rule.

Key Research Finding (Attempt 6)

SwitchHandler2 MUST have custom MapTrackColor/MapThumbColor because:

MaterialSwitch coloring uses TrackTintList = ColorStateList — fundamentally different API
C# extension methods resolve on static type, not runtime type → base map methods call wrong API

Summary

PR #33132 adds Material3 Switch support for Android in .NET MAUI, activated when UseMaterial3=true (MSBuild) / IsMaterial3Enabled=true (runtime). The core architecture is correct and necessary — SwitchHandler2 must have custom MapTrackColor/MapThumbColor because MaterialSwitch uses TrackTintList (ColorStateList) while SwitchCompat uses LayerDrawable.SetColorFilter(), making base handler map methods functionally wrong on MaterialSwitch.

However, there are actionable code quality issues that should be fixed before merge.

Root Cause (Issue #33131)

The Switch control on Android renders using SwitchCompat from AndroidX, which follows Material Design 2 conventions. Material Design 3 introduces MaterialSwitch (from Google Material library) with different visual states, shapes, and theming. Without this PR, enabling M3 has no effect on Switch.

Fix Quality

What the PR gets right:

✅ SwitchHandler2 : SwitchHandler inheritance pattern is consistent with PickerHandler2, RadioButtonHandler2, TimePickerHandler2
✅ MauiMaterialContextThemeWrapper correctly applies the M3 base theme to MaterialSwitch
✅ ConditionalWeakTable.GetValue() (thread-safe) for default tint caching — correctly fixed after prior review
✅ CheckedChangeListener refactored with WeakReference<SwitchHandler> and sealed keyword — good memory-safety improvement (unrelated to M3 but welcome)
✅ Handler registration properly gated behind IsMaterial3Enabled in AppHostBuilderExtensions.cs
✅ Screenshot tests added (Material3SwitchFeatureTests) with 6 baseline images
✅ internal + TODO comment approach matches other Handler2 classes — correct for pre-public API

Issues requiring changes:

🔴 Issue 1: `SwitchHandler2.Mapper` chains from `ViewMapper` instead of `SwitchHandler.Mapper`

// Current (WRONG):
public static new PropertyMapper<ISwitch, SwitchHandler2> Mapper =
    new(ViewMapper)  // ← skips all SwitchHandler-specific mappings
    { ... };

// Should be:
public static new PropertyMapper<ISwitch, SwitchHandler2> Mapper =
    new(SwitchHandler.Mapper)  // ← inherits base switch mappings
    { ... };

Impact: Any future property added to SwitchHandler.Mapper (e.g., accessibility, new switch API) will silently NOT apply to M3 switch. SwitchHandler2 will diverge from SwitchHandler as the API evolves. Compare: PickerHandler2.Mapper chains from SwitchHandler.Mapper (pattern to follow).

🟡 Issue 2: Silent visual bug when theme has no M3 tints (`?? Transparent` fallback)

// Current (potential bug):
static m => m.TrackTintList ?? ColorStateList.ValueOf(global::Android.Graphics.Color.Transparent)

// Fix (nullable-preserving):
sealed class TintEntry { public ColorStateList? Value; }
// factory: static m => new TintEntry { Value = m.TrackTintList }
// restore: materialSwitch.TrackTintList = entry.Value;

Impact: If a custom Android theme doesn't define M3 switch tints (valid), the initial TrackTintList is null. Caching Transparent and restoring it on color-clear makes the switch track invisible. Using a TintEntry wrapper (Attempt 5 in try-fix) safely preserves null. The comment says "in practice the fallback is never reached" — but this is an unverified assumption that will break for some users.

🟡 Issue 3: `RuntimeFeature.IsMaterial3Enabled` not cached

// Current: called on every MauiMaterialContextThemeWrapper construction
public static bool IsMaterial3Enabled =>
    AppContext.TryGetSwitch($"...", out bool isEnabled) ? isEnabled : false;

// Should be (matching IsMeterSupported pattern):
static readonly bool _isMaterial3Enabled = InitializeIsMaterial3Enabled();
public static bool IsMaterial3Enabled => _isMaterial3Enabled;

Impact: Minor performance — AppContext.TryGetSwitch does a dictionary lookup per call. Called on every M3 control construction. Other feature flags in the same file (IsHybridWebViewSupported, IsMeterSupported) are cached.

🟡 Issue 4: `MapIsOn` in SwitchHandler2 is redundant

public static new void MapIsOn(ISwitchHandler handler, ISwitch view)
{
    (handler.PlatformView as MaterialSwitch)?.UpdateIsOn(view);
}

The UpdateIsOn(this MSwitch, ISwitch) extension simply sets Checked = view.IsOn — identical to the base UpdateIsOn(this ASwitch, ISwitch). Since MaterialSwitch IS-A ASwitch, the base map method works correctly. This method can be removed from SwitchHandler2.Mapper and SwitchHandler.MapIsOn will be inherited (once Issue 1 is fixed).

Test Coverage Assessment

Tests exist (Material3SwitchFeatureTests) but have an architectural limitation: they rely on screenshot baselines but the test runner (BuildAndRunHostApp.ps1) doesn't set UseMaterial3=true at build time. This means CI cannot verify M3 behavior without special pipeline configuration. The PR should document or add CI configuration to enable M3 for the Material3 test category.

Suggested Changes Before Merge

Required: Change new(ViewMapper) → new(SwitchHandler.Mapper) in SwitchHandler2.Mapper
Required: Replace ?? ColorStateList.ValueOf(Transparent) with TintEntry nullable-preserving wrapper (or add clear comment with a Debug.Assert that the fallback is never reached)
Recommended: Cache IsMaterial3Enabled as static readonly bool in RuntimeFeature.cs
Optional: Remove redundant MapIsOn from SwitchHandler2 (after fixing Issue 1)
Recommended: Document CI/pipeline setup needed to run Material3 screenshot tests

### Description of Change

This PR adds Android `SwitchHandler2`, which uses the Material 3 `MaterialSwitch` widget when the `IsMaterial3Enabled` runtime feature flag is active (opt-in via `$(UseMaterial3)` MSBuild property, set by the base infrastructure PR #33074).

**Material 3 Switch handler (`src/Core/src/Handlers/Switch/SwitchHandler2.Android.cs`):**
- New `internal class SwitchHandler2 : SwitchHandler` that overrides `CreatePlatformView()` to return `MaterialSwitch` wrapped in `MauiMaterialContextThemeWrapper`
- Provides overridden `MapIsOn`, `MapTrackColor`, `MapThumbColor` that cast to `MaterialSwitch` and call the new `MSwitch` extension methods

**Material 3 extension methods (`src/Core/src/Platform/Android/SwitchExtensions.cs`):**
- Added `internal static` overloads of `UpdateIsOn`, `UpdateTrackColor`, `UpdateThumbColor` for `MSwitch` (alias for `MaterialSwitch`)
- `UpdateTrackColor`/`UpdateThumbColor` use `ConditionalWeakTable.GetValue()` (thread-safe factory) to cache the original theme tint per-instance, ensuring color resets restore the actual theme default even across Activity/theme changes
- Fallback to `ColorStateList.ValueOf(Transparent)` satisfies `ConditionalWeakTable`'s no-null-value constraint; in practice `MaterialSwitch` always has a theme-supplied tint

**Handler registration (`src/Controls/src/Core/Hosting/AppHostBuilderExtensions.cs`):**
- Moved `Switch → SwitchHandler` registration from the generic section into the Android `if/else` block
- When `RuntimeFeature.IsMaterial3Enabled`: registers `SwitchHandler2`; otherwise: `SwitchHandler`

**SwitchHandler listener improvement (`src/Core/src/Handlers/Switch/SwitchHandler.Android.cs`):**
- Replaced the shared property `CheckedChangeListener ChangeListener { get; } = new()` (with mutable `.Handler` field) with a per-connect-instance `CheckedChangeListener` that holds a `WeakReference<SwitchHandler>`
- Prevents potential retain cycles; `sealed` class prevents accidental subclassing

**Tests (`src/Controls/tests/TestCases.Shared.Tests/Tests/FeatureMatrix/Material3SwitchFeatureTests.cs`):**
- 6 Android-only screenshot tests (`#if ANDROID`) under `UITestCategories.Material3`
- Reuses the existing "Switch Feature Matrix" HostApp gallery page — native widget differs (MaterialSwitch vs SwitchCompat) so these produce separate baselines

Phase 2: Code Review

✅ Issues Already Addressed

Previous review rounds flagged several issues that have been resolved in the current implementation:

Issue	Status
Race condition in `ConditionalWeakTable` (`TryGetValue + Add`)	✅ Fixed — now uses `GetValue` with factory delegate
Redundant type/null checks in `UpdateThumbColor`	✅ Fixed in current diff
Mixed M2/M3 static field collision (shared `_defaultTintList`)	✅ Fixed — now per-instance via `ConditionalWeakTable<MSwitch, ...>`
Missing UI tests	✅ Added `Material3SwitchFeatureTests.cs` with 6 screenshot tests
`CheckedChangeListener` had shared mutable `Handler` property	✅ Fixed — now uses `WeakReference<SwitchHandler>` per instance

🔴 Critical Issues

1. Missing newline at end of SwitchHandler2.Android.cs

The file ends with } followed by \ No newline at end of file. MAUI (and most C# conventions) require a trailing newline. This causes noise in diffs.

// Add a blank newline at end of file

2. Missing newline at end of Material3SwitchFeatureTests.cs

Same issue — \ No newline at end of file at the end of the test file.

🟡 Medium Issues

3. Mixed indentation in SwitchHandler2.Android.cs Mapper initializer

// Current (mixed 2-space and tab):
public static new PropertyMapper<ISwitch, SwitchHandler2> Mapper =
  new(ViewMapper)
  {
	  [nameof(ISwitch.IsOn)] = MapIsOn,
	  [nameof(ISwitch.TrackColor)] = MapTrackColor,
	  [nameof(ISwitch.ThumbColor)] = MapThumbColor,
  };

The initializer body uses 2-space indent for the new(ViewMapper) and {/}, but tabs inside the block. MAUI uses tabs throughout — the entire initializer should be tab-indented:

public static new PropertyMapper<ISwitch, SwitchHandler2> Mapper =
	new(ViewMapper)
	{
		[nameof(ISwitch.IsOn)] = MapIsOn,
		[nameof(ISwitch.TrackColor)] = MapTrackColor,
		[nameof(ISwitch.ThumbColor)] = MapThumbColor,
	};

Same applies to the CommandMapper indentation:

// Current:
public static new CommandMapper<ISwitch, SwitchHandler2> CommandMapper =
	 new(ViewCommandMapper);  // extra leading space

4. IsMaterial3Enabled is not cached (performance consideration)

public static bool IsMaterial3Enabled =>
    AppContext.TryGetSwitch($"{FeatureSwitchPrefix}.{nameof(IsMaterial3Enabled)}", out bool isEnabled)
        ? isEnabled
        : IsMaterial3EnabledByDefault;

This calls AppContext.TryGetSwitch (a dictionary lookup) on every access. It is called at least once per MaterialSwitch instantiation in MauiMaterialContextThemeWrapper.Create(). While consistent with most other flags in this file (e.g., EnableMauiAspire), IsMeterSupported demonstrates the preferred cached pattern:

internal static bool IsMeterSupported { get; } = InitializeIsMeterSupported();

If IsMaterial3Enabled is checked in hot paths (per-control construction), caching is recommended to avoid repeated dictionary lookups.

🟢 Looks Good

SwitchHandler2 design: Correctly inherits from SwitchHandler, only overrides what's needed (CreatePlatformView + 3 mapper methods). The public static new mapper pattern matches what other Handler2 classes do (e.g., PickerHandler2, RadioButtonHandler2).
SwitchHandler2.Mapper base: Uses new(ViewMapper) — same as SwitchHandler.Mapper. All three ISwitch-specific properties (IsOn, TrackColor, ThumbColor) are explicitly re-mapped with Material3-aware implementations. No mappings are silently lost.
ConditionalWeakTable caching: The GetValue factory pattern is correct and thread-safe. The static readonly tables are appropriately scoped (per-MSwitch instance, not global). The fallback to Transparent is well-documented.
WeakReference listener: sealed class CheckedChangeListener with WeakReference<SwitchHandler> and TryGetTarget is the correct pattern for Java interop listeners in MAUI, preventing circular strong references through the Java bridge.
Handler registration conditional logic: Moving Switch out of the generic (non-Android) section into the Android if/else block is correct. All 3 code paths now register a handler for Switch (SwitchHandler2, SwitchHandler, or SwitchHandler).
Test quality: Material3SwitchFeatureTests uses tolerance: 0.5, retryTimeout: TimeSpan.FromSeconds(2) appropriately. Tests cover initial state, click, RTL, color combinations. Reusing the existing gallery page is pragmatic.
Screenshot baselines: 6 baseline PNGs for android-notch-36 are included.

Summary

Phase	Status
Title	🟡 Minor: remove trailing space, use imperative tense
Description	🟡 Needs update: remove references to base PR files, fix class name (`MaterialSwitchHandler` → `SwitchHandler2`), add note about listener improvement
Code — Critical	🔴 2 missing end-of-file newlines
Code — Medium	🟡 Mixed indentation in SwitchHandler2, uncached feature flag
Code — Overall	✅ Core implementation is solid; prior race conditions and listener issues resolved

Recommendation: Fix the two missing trailing newlines and the indentation before merge. Update the description to accurately reflect this PR's scope (not the base PR). The implementation approach is sound.

Thank you! ## Summary This PR adopts the [`dotnet/arcade-skills`](https://github.com/dotnet/arcade-skills) plugin system for CI investigation in dotnet/maui, replacing the need for custom in-repo PowerShell scripts. Two files are added: 1. **`.github/copilot/settings.json`** — repo-level plugin declaration that auto-installs the `dotnet-dnceng` plugin for all users 2. **`.github/skills/azdo-build-investigator/SKILL.md`** — thin MAUI-specific context supplement (~60 lines, no scripts) --- ## Background & Motivation ### The Problem When investigating CI failures on dotnet/maui PRs, contributors and AI agents need to: - Query Azure DevOps builds across 3 pipelines (`maui-pr`, `maui-pr-devicetests`, `maui-pr-uitests`) - Dig into Helix test logs for device test failures - Analyze MSBuild binlogs for obscure build failures - Detect hidden test failures caused by XHarness exiting with code 0 even when tests fail PR dotnet#34335 (`feature/azdo-ci-instructions`) addressed this with ~700 lines of custom PowerShell scripts. During review of that PR, we discovered [`dotnet/arcade-skills`](https://github.com/dotnet/arcade-skills) — a .NET engineering-maintained plugin that provides native MCP tooling for exactly this problem space, and already lists `dotnet/maui` as a supported repository. ### Why arcade-skills Instead of Custom Scripts The `dotnet-dnceng` plugin in arcade-skills provides: | MCP Server | Tool | Replaces | |------------|------|---------| | `ado-dnceng-public` | Native ADO queries via `@azure-devops/mcp` | `Get-BuildInfo.ps1`, `Get-BuildErrors.ps1`, `Get-PrBuildIds.ps1` | | `hlx` | Helix test infrastructure via `lewing.helix.mcp` | `Get-HelixLogs.ps1` | | `mcp-binlog-tool` | MSBuild binlog analysis via `baronfel.binlog.mcp` | `Get-BuildBinlogs.ps1` + manual `binlogtool` | MCP tools are first-class AI primitives — the AI calls them directly with structured parameters rather than running shell scripts and parsing text output. This is more reliable and maintainable. ### Auto-Loading (No User Action Required) The key mechanism that makes this work seamlessly: **`.github/copilot/settings.json`** supports `enabledPlugins` (introduced in Copilot CLI v0.0.422) — a "declarative plugin auto-install" that runs at session startup when a user opens this repository. Every user who opens dotnet/maui gets the `dotnet-dnceng` plugin with all its MCP servers automatically. No `/plugin install` command needed. ```json { "extraKnownMarketplaces": [ { "url": "https://github.com/dotnet/arcade-skills" } ], "enabledPlugins": ["dotnet-dnceng@dotnet-arcade-skills"] } ``` --- ## What the MAUI Context Skill Adds The arcade-skills `ci-analysis` skill is excellent but contains outdated MAUI-specific information (it lists `maui-public` as the pipeline name, which is wrong). The thin `azdo-build-investigator/SKILL.md` provides corrections and MAUI-specific domain knowledge: ### Correct Pipeline Names/IDs | Pipeline | Definition ID | Purpose | |----------|--------------|---------| | `maui-pr` | **302** | Main build — check first | | `maui-pr-devicetests` | **314** | Helix device tests | | `maui-pr-uitests` | **313** | Appium UI tests | ### XHarness Exit-0 Blind Spot XHarness (used in `maui-pr-devicetests`) **exits with code 0 even when tests fail**. The ADO job shows ✅ "Succeeded" while actual test failures hide inside Helix work items. The SKILL.md documents how to detect this via the Helix `ResultSummaryByBuild` API. This quirk was discovered while investigating PRs with the `s/agent-gate-failed` label where CI appeared green but tests were actually failing. ### Container Artifact Quirk for Binlogs MAUI build artifacts are **Container type** (not `PipelineArtifact`), so standard `az pipelines runs artifact download` does not work for binlogs. The SKILL.md documents the correct download approach using the ADO File Container API with Bearer auth. --- ## Relationship to PR dotnet#34335 PR dotnet#34335 (`feature/azdo-ci-instructions`) adds the same investigation capability via 5 custom PowerShell scripts. This PR supersedes that approach. The knowledge gained building those scripts (XHarness exit-0 discovery, Container artifact API approach, pipeline IDs) is preserved in the SKILL.md here. We recommend closing dotnet#34335 in favor of this approach, which: - Has ~5% of the code to maintain - Uses MCP tooling that will improve over time as arcade-skills evolves - Auto-loads for all contributors without any setup --- ## Files Changed ``` .github/copilot/settings.json (new) — repo-level plugin auto-install .github/skills/azdo-build-investigator/SKILL.md (new) — MAUI-specific CI context ``` ## Testing - Verified `.github/copilot/settings.json` schema matches Copilot CLI v0.0.422+ `enabledPlugins` format - Verified `dotnet-dnceng@dotnet-arcade-skills` resolves against the marketplace at `https://github.com/dotnet/arcade-skills/.github/plugin/marketplace.json` - SKILL.md pipeline IDs verified against live ADO builds: maui-pr=302, maui-pr-devicetests=314, maui-pr-uitests=313 /cc @PureWeen --------- Co-authored-by: github-actions[bot] <41898282+github-actions[bot]@users.noreply.github.com> Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

Addressed the valid concerns with the following changes:
SwitchHandler2.Android.cs: Changed the base mapper from ViewMapper to SwitchHandler.Mapper so all existing mappings (including IsOn) are inherited. Removed the explicit MapIsOn override and its mapper entry since they are no longer required.
SwitchExtensions.cs: Removed UpdateIsOn(this MSwitch ...) as MaterialSwitch extends SwitchCompat, and the base implementation already handles it correctly. Also updated UpdateTrackColor and UpdateThumbColor to use the TryGetValue+ Add pattern instead of GetValue, avoiding caching Transparent when the original tint is null, which could otherwise make the track/thumb invisible when the color is cleared.

Race condition concern on TryGetValue+ Add:
The race condition is not applicable here. MAUI's dispatch model ensures handler mappers always run on the main thread, so concurrent calls on the same MaterialSwitch instance cannot occur in practice.

Thank you!  ### Description of Change  This pull request adds support for Material 3 styling for the `Switch` control on Android in .NET MAUI. It introduces a new Material 3 switch handler, configures runtime feature toggling for Material 3, and adds the necessary Android resources and theming infrastructure for Material 3 support. **Material 3 Switch support and theming:** * Introduced a new `SwitchHandler2` for Android, which uses the Material 3 `MaterialSwitch` when the Material 3 feature is enabled. This handler includes property mapping for `IsOn`, `TrackColor`, and `ThumbColor`. * Updated `SwitchExtensions` to support updating properties (`IsOn`, `TrackColor`, `ThumbColor`) on both traditional and Material 3 switches.
