When restoring NuGet packages from an authenticated ADO package feed, Azure Artifacts credential provider needs to be installed to enable authentication. If a build error occurs because of an authentication failure against an ADO feed, MSBuildProjectBuilder should:
- If not in batch mode, help the user get Azure Artifacts credential provider installed (https://github.com/microsoft/artifacts-credprovider/blob/master/helpers/installcredprovider.ps1).
- If in batch mode, produce an actionable error.
