Inconsistent Debugging with MultiValueConverterExtension crash
This issue has been moved from a ticket on Developer Community.
[severity:It’s more difficult to complete my work]
The MultiValueConverterExtension from CommunityToolkit.Maui crashes on my iPad - you don’t even need to actually use it, just add a resource to a page. However I am reporting this as a problem with Visual Studio, because if I try to debug the project to see why it crashes, it won’t crash! Obviously I can’t give an end user software that only works when running the debugger, and I can’t troubleshoot issues if they behave differently between running the debugger and running normally.
This is very easily reproduced, at least on my machine.

A test project was included in my original post. Did you not receive it? Is it somehow incomplete?

It doesn’t look like it attached correctly, can you try again?

that's the trace, what's the exception ? will try to repro that
Might be worth trying to update to the latest version of the Toolkit which should be fully AOT compatible
Hi @vsfeedback. We have added the "s/try-latest-version" label to this issue, which indicates that we'd like you to try and reproduce this issue on the latest available public version. This can happen because we think that this issue was fixed in a version that has just been released, or the information provided by you indicates that you might be working with an older version.
You can install the latest version by installing the latest Visual Studio (Preview) with the .NET MAUI workload installed. If the issue still persists, please let us know with any additional details and ideally a reproduction project provided through a GitHub repository.
This issue will be closed automatically in 7 days if we do not hear back from you by then - please feel free to re-open it if you come back to this issue after that time.
