You can either exclude the failing assemblies from being optimized, or set the PublishReadyToRun property to false.

Note:

1. Workaround for this error is to set the PublishReadyToRun property to false or run dotnet publish -c Release -p:PublishReadyToRun=false
2. This also repro with MVC/WebAPI/Blazor.

Expected:
No error will occur.

Triage Summary

Area: area-blazor — The failing method is RemoteJSDataStream.CompletePipeAndDisposeStream in Microsoft.AspNetCore.Components.Server.Circuits, which is part of Blazor Server.
Type: bug — Clear reproduction steps, unexpected ILCompiler.CodeGenerationFailedException / IndexOutOfRangeException during dotnet publish with PublishReadyToRun=true.

Regression Info

• Previously working version: .NET 11 Preview 4
• Broken since: .NET 11 Preview 5 (SDK 11.0.100-preview.5.26268.112)
• Publishing a Razor/MVC app with PublishReadyToRun=true fails with an unhandled IndexOutOfRangeException inside the ReadyToRun ILCompiler when processing the async state machine for RemoteJSDataStream.CompletePipeAndDisposeStream. The workaround is to set PublishReadyToRun=false.

Potential Duplicates

• None found

Notes

• The stack trace originates entirely within dotnet/runtime (ILCompiler.ReadyToRun, CorInfoImpl.ReadyToRun.cs). The root cause is likely a runtime R2R compiler bug triggered by a code pattern in RemoteJSDataStream. This may need to be cross-filed or routed to the dotnet/runtime team.
• The issue already has the NativeAOT label, though this is actually a ReadyToRun (crossgen2) failure, not NativeAOT. The team may wish to relabel.
