…gration test jobs which now use the beta image with VS2026
Remove unnecessary fetch-depth: 0 (24 occurrences across 8 workflows), add NuGet package caching, scope overly broad artifact uploads, and use sparse checkout where only specific directories are needed. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Keep NuGet cache blocks added in previous commit; main had removed a blank line after checkout steps causing trivial conflicts. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Versioning.targets uses git describe --tags during MSBuild, so jobs that run dotnet build/test or MSBuild need full git history for version resolution. Restores fetch-depth: 0 for 6 build jobs while keeping shallow clones for the 18 non-build jobs. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Replace fetch-depth: 0 with filter: blob:none for 6 build jobs that need git commit history (for Versioning.targets git describe/rev-list) but don't need full blob downloads. Blobless clones fetch all commits and tags while deferring blob downloads to on-demand, reducing clone time while preserving versioning functionality. Affected jobs: build-integration-tests, build-unbounded-tests (all_solutions), Windows build (build_profiler), analyze-dotnet, analyze-cpp (codeql), run-unit-tests (unit_tests).

Same optimization as other build jobs — filter: blob:none provides commit history for Versioning.targets without full blob download. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
The filter input alone doesn't override actions/checkout's default shallow clone (depth=1, no tags). Both fetch-depth: 0 and filter: blob:none are needed together to get a full commit history with on-demand blob downloads. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
The run-artifactbuilder job calls generateBuildProperties.ps1 which uses git describe for versioning. It needs fetch-depth: 0 with filter: blob:none like the other build jobs. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

There was a problem hiding this comment.
I ran the post-deploy workflow in test mode from this branch and it passed: https://github.com/newrelic/newrelic-dotnet-agent/actions/runs/23014952701
Approved. 👍

Summary
Reduces CI overhead across 12 workflow files through four strategies:
fetch-depth: 0(full clone of all commits, tags, and file blobs). Most only need commit history for version tagging viagit describe. Addingfilter: blob:nonetells git to fetch commits and tags but download file blobs only on demand at checkout, reducing initial clone size while preserving versioning. All 13 barefetch-depth: 0occurrences now use blobless clones.actions/cacheto 7 build jobs, saving ~1-2 minutes per job by avoiding redundant package downloads. This was the biggest measurable improvement.siteextension_releasewas uploading the entire workspace; now uploads only the build output. Updateddeploy_siteextensiondownload path to match.post_deploy_agentnow check out only the directory they need.Test plan
