- Change FileVersionPrefix from 17.0 to 18.0 - Switch variable group from PTVS-Dev17 to PTVS-Dev18 - Switch pool from VSEngSS-MicroBuild2022-1ES to VSEng-MicroBuildVSStable - Update VisualStudio demand from 17.0 to 18.0 - Update integration tests pipeline source from PTVS-Build-Dev17 to PTVS-Build-Dev18 - Move VS bootstrapper step outside Non-PR conditional - Re-enable glass tests for PR builds
- Add dependsOn: build so test job waits for build to complete - Download Binaries artifact from build job instead of running MSBuild again - Copy binaries to expected \raw\binaries path
- Add 'Build Installer & Bootstrapper' pipeline parameter (default: false) - Condition installer build step, vsts drop, and bootstrapper on non-PR or parameter - Non-PR builds (CI/scheduled) always build installer as before - PR builds skip installer by default for faster builds - Can opt-in for PR builds by setting the parameter when manually queuing
- Move installer, vsts drop, bootstrapper, and BoM into a new 'installer' job - Installer job downloads build artifacts instead of rebuilding product - Test and installer jobs both depend on build and run in parallel - Build job is now leaner: product + tests only
- Remove 'Build tests' step from build.yml (saves ~1.5min in build job) - Add 'Build tests' step to run_tests.yml after downloading binaries - Add checkout and package restore to test job - Tests are only built when they're actually going to run
- Build tests back in build.yml (needed by build job) - Remove test build from run_tests.yml (just downloads binaries) - New 'nuget' job: downloads binaries, builds/signs/publishes NuGet package - Installer, test, and nuget jobs all run in parallel after build
Glass tests only need product binaries, not test project outputs. Test binaries are only used by the integration test pipeline. This saves ~1:37 of build time plus reduced SDL scanning.
- Test job doesn't need NuGet packages, pylance, or debugpy - Glass tests only need Python + product binaries + source scripts - Use windows-latest hosted pool (no VS/MSBuild needed) - Saves ~1:12 restore time and faster agent allocation

Pull request overview
This PR upgrades the PTVS build pipelines from Visual Studio Dev17 (VS 2022) to Dev18 (VS 2025) and implements significant pipeline restructuring to improve build performance through parallelization. The main build job (~19 min serial) has been split into 4 jobs that run in parallel after the initial build completes.
Changes:
- Upgraded all pipeline configurations from Dev17 to Dev18 (version references, variable groups, build pools, VS demands)
- Restructured main pipeline into 4 parallel jobs: build (product only), installer (conditional), test (conditional), and nuget (conditional)
- Added buildInstaller parameter to allow PR builds to skip installer/bootstrapper generation by default while enabling opt-in
- Optimized test job to download build artifacts instead of rebuilding, and removed unnecessary package restores
- Removed conditional Non-PR step logic to simplify pipeline execution

PR: Upgrade pipelines from Dev17 to Dev18 + pipeline optimizations
Dev17 → Dev18 upgrade
17.0 → 18.0
17.0 → 18.0
Pipeline restructuring (4 parallel jobs)
Previously everything ran in a single build job (~19 min serial). Now split into:
Jobs 2-4 run in parallel after the build job completes.
Key optimizations
