Summary
dotnet-public-npmfeed in the release deployment job, which does not check out the repository.npmAuthenticate@0and pass the authenticated file to the Marketplace step throughNPM_CONFIG_USERCONFIG.Why
The public feed permits anonymous downloads of saved packages, but fetching versions that have not yet been saved from upstream requires authentication. The publishing script intentionally bootstraps the latest VSCE through an unpinned
npxinvocation, so a newly selected VSCE version or transitive dependency can fail with npm E401 before Marketplace publishing starts.The existing Marketplace Azure service connection does not configure npm feed authentication. This change uses the job's Azure DevOps credentials for npm and leaves Marketplace authentication and the unpinned VSCE behavior unchanged.
Operational notes
