Pull request overview

This PR wires up Helix Job Monitor support across the runtime Azure DevOps pipelines by introducing a useHelixMonitor parameter through the relevant YAML templates, enabling it for the runtime pipeline test legs, and adding the Helix Job Monitor .NET tool/dependency so the monitor job can run.

Changes:

• Add a HelixJobMonitor job to eng/pipelines/runtime.yml (Build stage) using the shared eng/common template.
• Plumb a useHelixMonitor parameter through Helix-related pipeline templates and pass /p:EnableHelixJobMonitor=... through the various “send to helix” paths.
• Add Microsoft.DotNet.Helix.JobMonitor tool/dependency and pin it in .config/dotnet-tools.json.

eng/pipelines/common/templates/browser-wasm-coreclr-build-tests.yml:145

• This template hard-codes useHelixMonitor: true when invoking the libraries Helix template. Since other Helix templates were updated to accept a useHelixMonitor parameter (defaulting to false) and runtime.yml is now explicitly setting it, this hard-coded true makes the behavior inconsistent and harder to roll back/experiment with.

Consider adding a useHelixMonitor parameter to this template (default false) and threading it through instead of hard-coding true.

eng/pipelines/common/variables.yml:50

• enableHelixJobMonitor is set to true unconditionally, which turns on the new Helix monitor path for all runtime.yml runs immediately. The linked arcade rollout plan for HRJ/Job Monitor describes a phased rollout (including a dual-mode period). Consider defaulting this to false (or scoping it to specific pipelines/stages) so the feature can be enabled gradually and rolled back via variable override if needed.

  value: true

global.json:18

• The PR description says the Helix Job Monitor dependency is the same version as Arcade, but global.json keeps Microsoft.DotNet.Arcade.Sdk at 11.0.0-beta.26365.101 while Microsoft.DotNet.Helix.Sdk is bumped to 11.0.0-beta.26381.1 (and dotnet-tools.json pins the monitor tool to 11.0.0-beta.26381.1). Please clarify whether this version skew is intentional; if not, align the Arcade SDK version with the Helix/JobMonitor build you’re taking.

  "msbuild-sdks": {
    "Microsoft.DotNet.Arcade.Sdk": "11.0.0-beta.26365.101",

    "Microsoft.DotNet.SharedFramework.Sdk": "11.0.0-beta.26365.101",

eng/Version.Details.xml:73

• This change also updates Microsoft.DotNet.GenAPI (version+SHA) and moves Microsoft.DotNet.Helix.Sdk’s source URI from dotnet/dotnet to dotnet/arcade. If these dependency updates are required for Helix Job Monitor enablement, it would help to call that out explicitly (or otherwise keep this PR focused by avoiding unrelated toolset churn).

eng/Version.Details.xml:72

• This change updates Microsoft.DotNet.GenAPI to 11.0.0-beta.26363.117 (and a different SHA) as part of the Helix/JobMonitor update. Since the PR description doesn't mention GenAPI and this appears unrelated to Helix Job Monitor enablement, it would be good to either justify why this version shift is required here or split it into a separate dependency update PR.

    <Dependency Name="Microsoft.DotNet.GenAPI" Version="11.0.0-beta.26363.117">

eng/pipelines/runtime.yml:71

• The Helix job monitor template defaults allowNoHelixJobs to false (see /eng/common/core-templates/job/helix-job-monitor.yml). Since this job is enabled here whenever enableHelixJobMonitor is true, the Build stage can legitimately produce zero Helix submissions (e.g., PRs where all Helix legs are skipped by path conditions), which would make the monitor job fail. Consider opting in to allowNoHelixJobs: true here (or gate the job on a condition that guarantees at least one Helix submission).

        - template: /eng/common/core-templates/job/helix-job-monitor.yml

global.json:18

• PR description says the new Microsoft.DotNet.Helix.JobMonitor dependency is "same version as Arcade", but global.json still pins Microsoft.DotNet.Arcade.Sdk to 11.0.0-beta.26365.101 while Helix SDK/JobMonitor are 11.0.0-beta.26381.1. If the intent is version parity with Arcade, the Arcade SDK version (and any derived dependency metadata) likely needs to be updated too, or the PR description should be adjusted to match the actual versioning approach.

    "Microsoft.DotNet.Arcade.Sdk": "11.0.0-beta.26365.101",
    "Microsoft.DotNet.Helix.Sdk": "11.0.0-beta.26381.1",

eng/Version.Details.props:12

• This change introduces a duplicate property. The file already defines MicrosoftDotNetHelixSdkPackageVersion later in the same PropertyGroup, so the later (older) value will win and the Helix SDK version update won’t actually take effect.

eng/pipelines/runtime.yml:71

• The Helix job monitor is added unconditionally when enableHelixJobMonitor is true, but the template defaults allowNoHelixJobs=false. If a Build stage run ends up producing zero Helix jobs (e.g., path-based conditions skip all Helix legs), the monitor job may fail the stage. Consider opting into allowNoHelixJobs for runtime.yml to avoid spurious failures.
