Getting Error "Cannot determine the packages folder to restore NuGet packages" during azure could build is processing

Question

I'm getting the following error during Cloud Build

"##[error]Cannot determine the packages folder to restore NuGet packages. Please specify either -PackagesDirectory or -SolutionDirectory."

Answer 1

I ran into this error verbatim after running nuget.exe restore on a project that didn't actually reference any NuGet packages, however, within the project's directory sat a packages.config file containing an entry to a package. This config file was not included or referenced by the project, it was just sitting in the directory.

Deleting the stray packages.config file resolved the error.
