Description

  • Dependabot does not currently support lock files (dotnet restore --force-evaluate), however, there is a potential workaround.

Motivation and Context

  • Adds a GH action to "attempt" to support it, as using it is advantagous.

How Has This Been Tested?

  • Not really sure how to without trying in the real world...

Summary by CodeRabbit

  • Chores
    • Added an automated workflow to detect and update NuGet lockfiles for Dependabot PRs.
    • When updates are needed, the workflow commits and pushes lockfile updates to keep dependencies synchronized.

Walkthrough

Adds a new GitHub Actions workflow that runs on dependabot pull requests, executes dotnet restore --force-evaluate, checks for lockfile diffs, and commits & pushes NuGet lockfile updates when changes are detected.

Changes

Cohort / File(s) Summary
GitHub Actions workflow
​.github/workflows/dependabot-packagelock-update.yml
New workflow triggered on pull_request for dependabot branches. Runs on windows-latest, performs checkout, runs dotnet restore --force-evaluate, computes a git diff, and if changes exist configures git, commits (chore(deps): update NuGet lock file) and pushes the updates.

Estimated code review effort

🎯 2 (Simple) | ⏱️ ~10 minutes

  • Verify trigger filtering correctly matches dependabot branch names.
  • Confirm dotnet restore --force-evaluate is appropriate for intended lockfile updates.
  • Inspect git commit/push steps for correct user config and safe push behavior.
  • Validate diff detection command and conditions that gate committing.

8-8: Redundant condition check in job filter.

The job already filters for pull_request events via the on: trigger (line 3), so the github.event_name == 'pull_request' check in the if: condition is redundant and can be removed.

-    if: contains(github.head_ref, 'dependabot') && github.event_name == 'pull_request'

11-11: No action required—review comment is incorrect.

The latest release of actions/checkout is v5, not an outdated version. The workflow is already using the current stable version. No update is needed.

Likely an incorrect or invalid review comment.

⚠️ Potential issue | 🟡 Minor

Clarify intent of commented-out setup-dotnet step.

The commented code suggests uncertainty about which .NET versions to target. Either:

  • Enable the step if multi-version testing is required, or
  • Remove it with a brief comment explaining why setup-dotnet is not needed.

Leaving it commented may confuse future maintainers about whether this is incomplete work.

setup-dotnet step leaves unclear intent about .NET version testing; either
enable it to run against the listed .NET versions or remove the block and add a
short comment explaining why .NET setup is unnecessary for this workflow (e.g.,
no .NET code or testing in this job). Update the workflow by uncommenting and
configuring the step if multi-version testing is required, or delete the
commented lines and add a one-line explanatory comment to avoid future
confusion.

⚠️ Potential issue | 🟠 Major

Verify that dotnet restore succeeds before committing.

The workflow commits and pushes lock file changes without explicitly verifying that dotnet restore succeeded. If restore fails or completes partially, corrupted lock files could be committed. Consider adding error handling or a success check.

      - run: dotnet restore --force-evaluate
+        id: restore
+      - if: failure()
+        run: echo "dotnet restore failed" && exit 1
🤖 Prompt for AI Agents
.github/workflows/dependabot-packagelock-update.yml lines 23-23: the workflow
runs `dotnet restore --force-evaluate` but does not explicitly prevent
subsequent commit/push if restore fails; ensure the commit step only runs when
restore succeeds by adding an explicit failure check or gating the commit on the
restore step's success (for example, make the restore step fail the job on
non-zero exit and add `if: ${{ success() }}` to the commit/push step or add a
follow-up step that verifies the restore exit status and exits 1 on failure) so
corrupted or partial lockfiles are never committed.

⚠️ Potential issue | 🟠 Major

Add error handling for git push and verify push succeeds.

The git push command (line 36) runs without error handling. If the push fails (e.g., due to permission issues or conflicts), the workflow will fail, but there's no explicit feedback. Additionally, the push command doesn't specify the remote or branch, relying on implicit defaults.

For clarity and safety, consider:

  • Specifying the remote and branch explicitly.
  • Adding error handling to catch and report push failures clearly.

handling around the push so failures are detected and reported—capture the push
exit status and echo a clear error message then exit non‑zero if the push fails
(optionally retry once before failing).

@networkfusion to be honest this is way more work than handling the updates manually as we've been doing... 😅
Moreover, because (by the time being) the tool needs to work in VS2019 we can't just use the latest on several NuGets. So... again more time picking up which updates should be merged or not...
