II. Issues

2.1 Top 5 Active Issues:

We consider active issues to be issues that that have been commented on most frequently within the last week. Bot comments are omitted.

1. [PLATFORM/MACOS] [AREA-TEMPLATES] [S/VERIFIED] [S/TRIAGED] MAUI template project does not build using the .net CLI: This issue describes a problem where a new .NET MAUI App template project builds successfully in Visual Studio but fails to build using the .NET CLI on a GitHub Action or command line, specifically due to a missing target for 'net10.0-maccatalyst/maccatalyst-arm64' in the project assets file. The error suggests that the project’s TargetFrameworks and RuntimeIdentifiers may need adjustment to include the appropriate mac catalyst arm64 target, and the problem has been reproduced and validated on Mac platforms with multiple .NET MAUI versions.

   • Comments confirm the issue is reproducible with a default MAUI template using the CLI build commands, showing the same error about missing targets in the assets file, and validation was performed on Mac with different .NET MAUI versions, reinforcing the problem’s consistency across environments.
   • Number of comments this week: 2

2. [T/BUG] [PLATFORM/IOS] [AREA-CONTROLS-TABBEDPAGE] [S/VERIFIED] [S/TRIAGED] [VERSION/IOS-26] iOS 26 TabBar has opaque background: This issue describes a problem on iOS 26 where the TabBar in a TabbedPage remains opaque instead of showing a liquid glass effect, causing layout inconsistencies. A workaround involving setting a negative bottom margin and corresponding positive bottom padding on the outer grid temporarily resolves the visual issue.

   • The comments confirm the issue is reproducible across multiple .NET MAUI versions on iOS, with a video provided for demonstration; additional screenshots were deemed unnecessary after the video was shared.
   • Number of comments this week: 2

3. [T/BUG] [PLATFORM/ANDROID] [P/0] [AREA-CONTROLS-COLLECTIONVIEW] [S/VERIFIED] [S/TRIAGED] [I/REGRESSION] [CSI-NEW] [REGRESSED-IN-10.0.60] [MAUI] I3_Sizing_Dynamic item sizing - After dragging the scrollbar, all images will automatically return to their original size.: This issue describes a regression in the Microsoft.Maui.Controls library where images dynamically resized by the user revert to their original size after dragging the scrollbar in the I3_Sizing_Dynamic item sizing test on Android. The problem occurs starting from version 10.0.60-ci.inflight.26181.6 and does not reproduce in earlier versions such as 10.0.50 and 10.0.51.

   • The comments confirm the issue is reproducible on the specified version and platform, provide visual evidence comparing working and broken versions, and identify a regression pull request responsible for the problem, noting it only affects the Candidate branch and not the main branch.
   • Number of comments this week: 2

4. [T/BUG] [PLATFORM/WINDOWS] [AREA-CONTROLS-COLLECTIONVIEW] [S/VERIFIED] [S/TRIAGED] [PARTNER/SYNCFUSION] [COLLECTIONVIEW-WINUI-CV2] [WinUI][CollectionView2] Selection Appearance Differs from CV1: This issue reports that the selection appearance in the CollectionView2 implementation for WinUI differs from the original CollectionView1, with the selected item being highlighted by a full border rather than the expected selection color and indicator on the left side. Additionally, in multiple selection mode, the checkbox is positioned on the right side instead of the left, causing inconsistency with the previous behavior in .NET MAUI.

   • The comment confirms that the issue has been validated and is reproducible on the Windows platform using Visual Studio 18.4.1 in the BugFixes_WinUI_CV2 branch.
   • Number of comments this week: 1

5. [T/BUG] [PLATFORM/WINDOWS] [AREA-CONTROLS-COLLECTIONVIEW] [S/VERIFIED] [S/TRIAGED] [PARTNER/SYNCFUSION] [COLLECTIONVIEW-WINUI-CV2] [WinUI][CollectionView2]GroupHeader Appearance Differs from CV1: This issue concerns a discrepancy in the visual rendering of the GroupHeader in CollectionView2 compared to CollectionView1, specifically regarding the spacing and alignment around the GroupHeader and grouped items on the Windows platform. The user reports that the current implementation lacks the additional spacing present in the previous version, resulting in a different appearance that is considered a regression from earlier .NET MAUI behavior.

   • The comment confirms that the issue is reproducible on the Windows platform using Visual Studio 18.4.1 in the BugFixes_WinUI_CV2 branch, validating the problem described in the original report.
   • Number of comments this week: 1

Other Open Pull Requests

• WPF BlazorWebView Performance Optimization: This pull request introduces a new UseCompositionControl dependency property to the WPF BlazorWebView that allows developers to opt out of using the WebView2CompositionControl, which causes rendering overhead. This enables improved Razor component performance when XAML-over-WebView layering is not needed.
  • pull/34764

• RadioButtonGroup Functionality Fix in .NET 10: This pull request fixes the issue where RadioButtonGroup controls do not function correctly when RadioButtons are placed inside a ContentView by updating the equality check and improving root resolution logic. These changes prevent unintended auto-selection and ensure other radio buttons in the group are correctly unchecked during ControlTemplate inflation.
  • pull/34781

• XamlC MSBuild Target Incrementality Improvement: This pull request fixes the incrementality of the XamlC MSBuild target for Debug builds by splitting it into two mutually exclusive targets for Release and Debug. This prevents unnecessary re-runs of XamlC on C#-only changes and improves MAUI Android inner loop build performance.
  • pull/34742

• GitHub Actions Workflow Agent Container Testing: This experimental pull request verifies whether the GitHub Actions workflow agent container can run dotnet build by checking NuGet restore access, CLI availability, and environment variable exposure. It serves as a test to identify potential AWF firewall or environment issues in the container.
  • pull/34762

• Android Modal Page Keyboard Dismissal Fix: This pull request fixes the HideSoftInputOnTapped feature on Android modal pages by overriding DispatchTouchEvent to forward touch events from modal dialogs to the main MAUI window. This enables the keyboard to be dismissed when tapping outside input fields on modal pages.
  • pull/34770

• Windows App SDK and Dependencies Update: This pull request updates the Windows App SDK to version 2.0.0-preview2 along with related dependencies and modifies NuGet configuration to include nuget.org for unresolved preview packages. It verifies successful local builds across multiple Windows solutions and device tests.
  • pull/34791

• Skill Validator Configuration for Test Verification: This pull request adds an eval.yaml configuration for the verify-tests-fail-without-fix skill, enabling comprehensive empirical A/B validation through skill-validator. It includes multiple scenarios testing verification modes, negative triggers, edge cases, and regressions to ensure tests catch bugs without vocabulary overfitting.
  • pull/34815

• Windows ScrollView Scroll Orientation Bug Fix: This pull request fixes a Windows-specific bug where setting the scroll orientation to Neither caused scroll offsets to reset by changing scroll bars to Hidden instead of Disabled. It preserves scroll position and includes manual and automated tests to verify the fix.
  • pull/34827

• Android CollectionView Dynamic Item Resize Fix: This pull request fixes an issue where dynamically resized items in Android CollectionView reset to their original size after scrolling off-screen and back. It modifies recycling logic to preserve the MAUI view reference and reconnect the native handler without recreating the view.
  • pull/34828

• Regression Prevention via Deleted Lines Detection: This pull request adds a GitHub Actions workflow and scripts that detect when pull requests remove lines of code introduced by prior bug fixes. It prevents regressions by tracing deleted lines back to their original commits and flagging such removals as critical.
  • pull/34768

• macOS UI Test Pools Migration to Shared Infrastructure: This pull request moves the macOS UI test pools in the ci-uitests.yml configuration to the ACES Shared Infrastructure. It updates public and internal macOS test pools to align with the shared pool setup used for Android and iOS UI tests in the same pipeline.
  • pull/34790

• Branch Guard Addition to GitHub Workflow: This pull request adds a branch guard to the merge-net11-to-release GitHub workflow to ensure the job only runs when triggered from the correct branch (net11.0). This prevents silent no-op executions when triggered from the default main branch via workflow_dispatch or scheduled events.
  • pull/34797

• iOS Simulator Installation Skip in Pack Pipeline: This pull request backports a change that skips the installation of iOS simulators in the official pack pipeline. This resolves timeout issues on macOS agents and prevents build production blocks by focusing the pipeline solely on building and packing NuGet packages.
  • pull/34802

• Azure DevOps Pipeline Gradle Cache Template: This pull request introduces a shared Azure DevOps pipeline template to cache Gradle downloads between CI runs by persisting the ~/.gradle/caches directory. This prevents intermittent build failures caused by transient network or DNS issues during Maven dependency resolution in Android binding builds.
  • pull/34804

• SDK Provisioning API Levels Update: This pull request updates the SDK provisioning API levels by adding android-36.1 as the default and including android-37 to the provisioning list. This fixes CI macOS build failures caused by missing android.jar files for API level 36.1 after the AndroidTargetFrameworkVersion bump.
  • pull/34805
