Brief description of tool

Azure DevOps provides the ability to download artifacts using nuget, which is a Microsoft-developed tool. It is available on macOS 13 & macOS 14 and needed for build scripts that download artifacts either from nuget.org or a private Azure DevOps artifacts nuget feed.

My team is attempting to migrate to macOS 15 runner images and builds are failing because, while our Windows and Linux images all have Nuget (and our macOS 13 images have Nuget), the macOS 15 machines are missing this tool.

Mono is necessary because Nuget needs Mono in order to run.

dotnet nuget is not a replacement for nuget.exe, because it doesn't have the ability to list available packages or download individual packages to specific directories.

Hi @DSMitten -
Please note that Mono and NuGet will not be included in the macOS 15 runner images, as we aim to maintain image as light weighted.
