Facing the same here.

[zahrabayatt]

Any updates on this?

[IlyaBausovAkvelon]

@zahrabayatt we are still working on this.

[kyurkchyan]

Same issue :( It's very frustrating

[tpitman]

Another one with the same issue. Any fix coming or is this even being worked on?

[Mogikan]

Is it a joke? Joined the party. Almost a year elapsed.

[busitech]

We are facing the same problem here.

[DmitriyKirakosyan]

Hello everyone, Due to shifting priorities, we've had to postpone the work on MAUI MacCatalyst. However, please note that this task remains a high priority on our board. We are committed to addressing the issue at the earliest opportunity. Thanks for your patience and understanding.

[AndreasReitberger]

Still facing this issue. Any ETA for a fix? It's been awhile.

[dfernandezramos]

Hi there. I am reproducing the issue on a macBook PRO M1 with macOS Sonoma. My application is net7 using Avalonia 11

[indyjason79]

Any updates on this?

[alimuhammadiiii]

Any news on this?

[Mogikan]

Two years ago they stopped planning development for the next year and seemed to stop even maintaining this product. Created this product to kill hockeyapp and now stopped development. What are the alternatives for this obsolete product? Google Firebase?

[busitech]

Wow, that's terrible news. Did Microsoft announce this officially?

[NPadrutt]

@busitech what I would consider at least an indicator for what @Mogikan is saying is that the roadmap was never updated since 2022: https://github.com/Microsoft/appcenter/wiki/Roadmap

Not sure if this is being worked on, but I've been using the below change for a few months and its been working fine. Binaries for maccatalyst taken from the latest xcframework package.

That's awesome! If it's working, why not doing a PR? @thewizrd

I am unclear how to use the 5.0.4 version. Even though it is marked latest, it is not visible in nuget. I am not a .NET expert, but is there a way to have my IDE (Rider) find this 5.0.4 nuget somehow?

[DmitriyKirakosyan]

Hi everyone, I prepared the maccatalyst support PR, based on https://github.com/microsoft/appcenter-sdk-dotnet/issues/1702/#issuecomment-1907191123 (thanks a lot to @thewizrd). We will merge the PR once CI is fixed.

[mhrastegari]

@DmitriyKirakosyan And when (or how) does CI getting fixed? :") Because it seems you guys are pending/waiting for something...

[vladPanasiuk]

@DmitriyKirakosyan Any news about this fix?

[mhrastegari]

Still having this issue with Microsoft.AppCenter.Crashes on v5.0.4 .NET Version: 8.0.300

[AndreasReitberger]

As far as I can remember, AppCenter is shutdown by end of March 2025. So I guess there will be no efforts to fix this issue at all...

[MikhailSuendukov]

Hello, the AppCenter .NET SDK v5.0.4 has been released, including a fix for this issue. Therefore, I am closing this issue.

[mhrastegari]

Did you even test it? 🙂 @MikhailSuendukov

[tylerwilson]

Same, just tried 5.0.4 and same issue:

System.TypeInitializationException: The type initializer for 'Microsoft.AppCenter.Utils.ApplicationLifecycleHelperDesktop' threw an exception. ---> System.IO.FileNotFoundException: Could not load file or assembly 'System.Windows.Forms, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' or one of its dependencies.

[domneedham]

Also facing this issue still with 5.0.4 for Maccatalyst.

[sovdchains]

5.0.5 seems to have fixed the issue

[MikhailSuendukov]

Hello, the AppCenter .NET SDK v5.0.5 with the fix for this issue has been released.

[Mogikan]

Forget about appcenter. It is now officially announced that they will shutdown website next year.

Wow, that's terrible news. Did Microsoft announce this officially?

Yes
