Debugger Interruptions on iOS with SfScheduler in .NET MAUI

[Aytekin Ozdemir]

Hi team,

I'm encountering a runtime issue with the SfScheduler control in my .NET MAUI application. The control works flawlessly on both iOS and Android if I simply deploy the app without attaching the debugger.

However, when I run the app on iOS with the Visual Studio debugger attached, the app hits multiple exceptions like the one below:

```

System.Resources.MissingManifestResourceException

Message=Could not find the resource "Syncfusion.Maui.Scheduler.SfScheduler.Resources.SfScheduler.resources" among the resources "" embedded in the assembly "Syncfusion.Maui.Scheduler", nor among the resources in any satellite assemblies for the specified culture. Perhaps the resources were embedded with an incorrect name.

```

```

System.IO.FileNotFoundException

  Message=Could not load file or assembly '/var/mobile/Containers/Data/Application/280B2114-DF73-4981-B258-334C7CC8549B/Documents/MyAppMauiApp.content/Syncfusion.Maui.Scheduler.resources.dll' or one of its dependencies.

```

These errors only occur on iOS (not on Android), and the debugger stops execution several times, requiring me to press F5 repeatedly to continue. Once past these interruptions, the app functions normally.

Is there a known workaround or fix for this issue? Or perhaps a recommended way to suppress these debugger breaks for known benign exceptions?

Thanks in advance!

Hi Aytekin,

 

Thank you for reporting this behavior.

We’ve reviewed your description and attempted to reproduce the issue by running the SfScheduler sample with the debugger attached on iOS, but we were unable to replicate the runtime exceptions you encountered.

For your convenience, we’ve shared a working sample that reflects the setup. Kindly check and let us know the following:

• Is the issue reproducible in the sample we provided?
• If not, could you modify the sample to replicate the issue based on your specific implementation or usage scenario?

To assist you more effectively, please also share the following details:

• The version of Syncfusion.Maui.Scheduler you're using
• The version of Microsoft.Maui.Controls in your project
• The target iOS version and device model where the issue occurs
• Any specific settings or debugging options you’ve enabled in Visual Studio or VS Code that might influence behavior

Once we have this information, we’ll be better equipped to investigate further and recommend appropriate workarounds or suppressions for benign debugger interruptions.

Looking forward to your reply!

Regards,
Priyadharshni M
