When using mudblazor in a .NET 7 Maui Blazor iOS app, the app does not work when published to .ipa for use in App Store or Ad Hoc. App runs fine when run in Debug or Release mode on Device.

I have the exact same issue, also with MudTextField and I don't have any clue on how to solve this.
It only fails when deployed through an .ipa file (but I don't seem to be able to catch the exception)

[QwertyMC]

Any thoughts on this? I've spent quite a bit of time designing this app and not cannot seem to publish it to App Store. Any help would be appreciated! Thank You.

Thanks for contacting us. Can you try the suggestion here and see if that helps: #12537 (comment)?

@lambdageek what should customers do in these situations?

@vargaz Is this related to dotnet/runtime#83003 - from the error it sounds like this is also something about delegate invoke wrappers and callvirt.

[lambdageek]

On second thought, this might be due to PropertySetter not being AOT friendly https:/dotnet/aspnetcore/blob/7c931425134d8cf54c82b29baba7ff277849f6bf/src/Components/Components/src/Reflection/PropertySetter.cs#L31-L36

I don't think creating delegates like this will work with AOT - is that right, @vargaz ?

[vargaz]

Same issue as:
dotnet/runtime#78889

[lambdageek]

@vargaz How come it only happens in the app store? shouldn't Release builds deployed on device produce the same problem?

[QwertyMC]

@mkArtakMSFTusing UseInterpreter True` does not help the situation.

@vargaz How come it only happens in the app store? shouldn't Release builds deployed on device produce the same problem?

No idea, but the underlying problem appears the same.

[mkArtakMSFT]

Closing as a dupe of dotnet/runtime#78889

@vargaz do you plan to patch this fix?

[vargaz]

Its in our queue to fix.

[QwertyMC]

@mkArtakMSFT What does not planned mean? There is no effort to resolve this issue?

[vargaz]

Its a duplicate, the issue will be tracked in:

dotnet/runtime#78889
