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.
-
[iOS] Modal-Page crashes: This issue reports frequent crashes on iOS related to modal pages in a MAUI application, where an InvalidOperationException occurs because the PageHandler cannot be converted to a UIView. The reporter suspects the problem arises from timing issues when opening and closing pop-ups, especially when switching between the app and OneDrive, and requests the MAUI team to add null checks in the relevant code to prevent these crashes despite the inability to reproduce the issue locally.
- The comments emphasize the difficulty of diagnosing the problem without a reproducible example or relevant code, with the reporter providing additional context about their popup implementation and crash details from Sentry. Other participants inquire about iOS version specifics and suggest sharing more diagnostic data, while the reporter confirms the crash affects all iOS versions and shares an extensive stack trace to aid investigation.
- Number of comments this week: 4
-
Getting Null Point Exception while opening the application in debug mode: This issue describes a NullReferenceException occurring when opening an Android application in debug mode using .NET MAUI with Visual Studio 2022 version 17.14.14. The error appears related to the ShellToolbarTracker component in the Android compatibility handlers, causing the app to crash during initialization in debug but not in release mode.
- The comments reveal that the exception is suspected to originate from a specific line in ShellToolbarTracker.cs, with requests for more environment details and sample projects. Multiple users confirm experiencing the same issue after updating Visual Studio to 17.14, noting that disabling FastDev allows debugging to work but with significantly reduced speed.
- Number of comments this week: 4
-
Invalid project item - a file item cannot end with a path seperator: This issue describes a problem where a .NET MAUI project fails to load because a file item in the project ends with a path separator, causing an invalid project item error. The user observes that deleting the project's obj directory temporarily resolves the issue, but it recurs when reopening the solution, and the problematic path appears to be generated automatically by the build tooling rather than explicitly referenced in the project files.
- The comments involve requests for more details about the project setup and attempts to identify the root cause, including suggestions to delete temporary Visual Studio files. The user reports that project names do not end with a path separator and suspects the Android build tooling might be generating incorrect paths, while maintainers express willingness to help but need further information to diagnose the edge case.
- Number of comments this week: 4
-
IntelliSense stops working after replacing 2021 with global in MAUI XAML namespace: This issue describes a problem where updating the XAML namespace declaration in a MAUI project from the 2021 schema to the global schema causes IntelliSense to stop functioning entirely on the affected pages. Users report that after this change, there are no auto-complete suggestions, no property or control recognition, and no error highlights, and the problem persists even after cleaning and restarting the project, but reverting to the 2021 namespace restores IntelliSense functionality.
- The comments confirm the issue is reproducible in Visual Studio 17.14.16 Preview 1.0 and detail that IntelliSense initially works after the namespace change but fails after closing and reopening the solution with cleaned build folders; the x:Class attribute becomes greyed out, and no IntelliSense features are available thereafter, with consistent behavior across new and existing projects.
- Number of comments this week: 3
-
MAUI: Windows: FilePicker: Returns wrong ContentType for *.webp files: Returns app/octet-stream.: This issue reports that on the Windows platform, the FilePicker component in MAUI incorrectly returns the MIME content type for *.webp files as 'application/octet-stream' instead of the correct 'image/webp'. The problem does not occur on Android or iOS (14+), where the content type is returned correctly, and it has been verified in specific MAUI and Visual Studio preview versions.
- The single comment confirms the issue can be reproduced on Windows using Visual Studio 17.14.16 Preview 1.0 with MAUI versions 9.0.0 and 9.0.110, and provides a sample project to demonstrate the problem.
- Number of comments this week: 1
2.2 Top 5 Stale Issues:
We consider stale issues to be issues that has had no activity within the last 30 days. The team should work together to get these issues resolved and closed as soon as possible.
- Nullable Enums do not bind in XAML: This issue describes a problem where nullable enums fail to bind correctly to a bindable property within a custom control in a XAML environment, with the property setter not being triggered at all. The user provides detailed reproduction steps and notes that the issue affects multiple platforms including iOS and Android, with no known workaround other than avoiding nullable enums by adding an explicit unset or none value to the enum.
- App crash after invoked FilePicker.Default.PickAsync in administrator mode and release mode of the Unpackaged app: This issue describes an application crash that occurs specifically when invoking the FilePicker.Default.PickAsync method in an unpackaged app running in administrator mode and release configuration on Windows 10 version 19041. The problem is reproducible by publishing the app with certain .NET 8.0 settings, launching it as an administrator, and attempting to choose a file, which unexpectedly causes the app to crash instead of functioning normally.
- Global defined EventTriggers get triggered twice: This issue describes a problem where an EventTrigger defined globally in a style causes its invoke method to be called twice, resulting in duplicate event handling. The user notes that applying the EventTrigger through a named style with a key triggers the event only once, indicating a discrepancy in behavior between global and keyed style definitions across multiple platforms including iOS, Android, and Windows.
- Path with ArcSegments is sporadically drawn offset from expected arc: This issue describes a sporadic rendering problem in .NET Maui where ArcSegments used to draw large arcs greater than 180 degrees are occasionally offset from their expected starting positions, causing clipping and misalignment especially when overlaid on correctly drawn arcs. The problem occurs across Windows, Android, and iOS platforms, is more frequent near the 180-degree threshold and with thicker strokes, and persists despite attempted workarounds such as using multiple smaller arcs or manually drawing arcs with line segments, with the issue notably reappearing during animations.
- .NET Maui does not support FontAutoScalingEnabled for windows platform: This issue highlights that the .NET Maui framework does not currently support disabling font auto-scaling on the Windows platform, causing text sizes to increase unexpectedly when the display scaling is changed. Specifically, setting the Label.FontAutoScalingEnabled property to false has no effect, resulting in larger text sizes when running the application on Windows machines with display scaling factors greater than 1.0.
2.3 Open Issues
This section lists, groups, and then summarizes issues that were created within the last week in the repository.
Issues Opened This Week: 13
Summarized Issues:
- UI Rendering and Visual Issues on Windows and Android: Several issues describe visual and interaction problems across Windows and Android platforms, including the BoxView shadow not matching corner radius on Windows, the Switch control becoming invisible on hover after theme changes, and the CollectionView's RemainingItemsThreshold incorrectly counting header/footer elements on Android, causing loading events to fail. Additionally, Android users face scrolling issues with large entry text boxes where standard gestures do not work, requiring cursor dragging instead.
- issues/31814, issues/31819, issues/31821, issues/31836
- Platform-Specific Deployment and Crash Issues: Deployment and runtime stability problems occur on Windows, iOS, and Android platforms, including incorrect file paths due to MauiAsset LogicalName on Windows preventing proper deployment, a crash on iOS caused by an InvalidOperationException during modal page layout updates, and a NullReferenceException on Android during ShellToolbarTracker initialization in debug mode. These issues affect app reliability and require platform-specific fixes.
- issues/31818, issues/31829, issues/31834
- Performance and Regression Bugs on macOS and iOS: Performance regressions and UI bugs have been reported in .NET MAUI 10 affecting macOS and iOS, including significant slowdowns and freezing when resizing windows on Mac with specific list configurations, and a failure of the "KeepLastItemInView" scroll mode to maintain visibility of the last list item on macOS and iOS. Additionally, a persistent white line appears on iOS simulator screen rotations, indicating graphical glitches.
- issues/31824, issues/31825, issues/31826
- Visual Studio and XAML Development Experience Issues: Development workflow is impacted by issues such as IntelliSense completely stopping on MAUI XAML pages after changing the namespace declaration, resulting in loss of auto-complete, property recognition, and error highlights until the namespace is reverted and Visual Studio restarted. Another problem causes .NET MAUI projects to fail loading in Visual Studio due to invalid project items generated in the obj directory, requiring manual cleanup to resolve.
- issues/31822, issues/31843
- Diagnostic and Telemetry Configuration Considerations: There is a discussion about enabling MAUI SDK diagnostics by default in the Aspire integration within the MAUI service defaults template, balancing the benefit of out-of-the-box performance information against the risk of generating excessive diagnostic data. This reflects ongoing considerations for improving developer tooling and telemetry.
