Hey @dotnet/aspnet-build, looks like this PR is something you want to take a look at.

        <HelixAvailableTargetQueue Include="Ubuntu.2004.Amd64.Open" Platform="Linux" />

+        <HelixAvailableTargetQueue Include="OSX.26.Amd64.Open" Platform="OSX" />


Should this be Arm64 ?

It probably should long-term, I'll see what happens if I switch it

1st run all good

wtgodbe · 2026-06-10T07:32:52Z

CI finished (builds 1457157, 1457158, 1457159). 2 Helix test failures, both on aspnetcore-ci → Tests: Helix x64 Subset 2:

Microsoft.AspNetCore.Components.ComponentsMetricsTest.FailParametersSync_RecordsErrorMetric
- Queue: OSX.26.Arm64.Open
- Reason: Assert.True() Failure — Expected: True, Actual: False
Microsoft.AspNetCore.Components.Tests--net11.0 Work Item (work-item crash)
- Queue: OSX.26.Arm64.Open
- Reason: Helix work item failed — "Often this is due to a test crash" (same Components.Tests assembly as the assert failure above; the crash and the failing assert are in the same work item).

(aspnetcore-quarantined-pr and aspnetcore-components-e2e only partiallySucceeded and their checks passed — quarantined/retried-flaky, not CI failures.)

wtgodbe · 2026-06-10T09:32:33Z

CI finished (builds 1457284, 1457285, 1457286). No Helix test failures.

For context, the two red legs were not Helix:

aspnetcore-ci → Build Build: macOS x64: a build/compile failure (no tests ran on Helix here).
aspnetcore-components-e2e → ComponentsE2E-Linux-Release-xunit (Selenium/Chrome on the AzDO agent, not a Helix queue): TempDataSessionStorageTest.TempDataPersistWithoutAccessing failed with StaleElementReferenceException (chrome 147) — a known e2e flake.
