The Final Piece: How to Trigger PR Builds
27 October 2025
Stop relying on confusing YAML blocks for PR builds!
The modern, secure way to validate Pull Requests is through Azure DevOps Branch Policies.
🔑 The Fix: Simply go to Repos > Branches and set your main Assembly Line pipeline (your fast-running pipeline) as a Required Build Validation for your develop and main branches.
This makes the Azure DevOps UI the single source of truth for PR triggers. Your Deploy stage will automatically skip deployment because it recognizes the build reason is PullRequest—giving you fast, secure testing without any accidental production pushes!
Control your PR quality directly from the UI, and let your YAML focus on deployment!
