Sorry it was in Xamarin.Ios.Common.After.Targets

Dont worry when I removed the windows target the error disappeared. Would still like it to work with windows 11 though

I tried to repro this using your project but I don't see the failure. I didn't try building for iPad from VS, but publishing on the mac works just fine it seems.

Could you please provide more details:

• What version of .NET SDK you have
• What is the full error - there should be a callstack from the illink cool. You might need to capture msbuild binlog to get it though
• Did you try to build/publish this project on a mac directly?

Did you build for the "windows machine "? I only built for the ipad as target. This is a net 8 project Also the repository i have on Github is obviously the latest version of the project with windows and android targets taken out so maybe you built that one? I think if you include the windows target you will see the issue reappear? Let me know. I would like a Windows app at some point. Regards nick Sent from Outlook for AndroidFrom: dotnet-policy-service[bot] ***@***.***>Sent: Tuesday, January 7, 2025 10:05:23 amTo: dotnet/runtime ***@***.***>Cc: nick hunter blair ***@***.***>; Author ***@***.***>Subject: Re: [dotnet/runtime] IL Trimmer has encountered an unexpected error (Issue #111089) This issue has been marked needs-author-action and may be missing some important information. —Reply to this email directly, view it on GitHub, or unsubscribe.You are receiving this because you authored the thread.Message ID: ***@***.***>
