This should save something like 30s/insertion, which isn't important, and just generally avoid unnecessary work.

Pull request overview

This PR updates the Visual Studio insertion Azure Pipeline to skip repository checkout in jobs that only use downloaded pipeline artifacts and inline scripts, reducing unnecessary work and slightly improving insertion runtime.

Changes:

  • Disable checkout in the RetainBuild stage job to avoid fetching sources when only inline PowerShell tasks run.
  • Disable checkout in the VSInsertion stage job to avoid fetching sources when the job operates on pipeline artifacts and tasks.

24/24 dimensions clean — no findings.

Verified that neither job references source files: no $(Build.SourcesDirectory) or $(System.DefaultWorkingDirectory) usage. All tasks use pipeline artifacts ($(Build.ArtifactStagingDirectory), $(Pipeline.Workspace)) and inline scripts. The checkout: none optimization is safe and well-documented with the inline comment.
