Azure Artifacts does not own any part of the UseDotNet task

[smg-bg]

@jmyersmsft how is Azure Artifacts related? I saw that the source code for the UseDotNet task is in the current repo where I've opened this tickeet.

[jmyersmsft]

Sorry, this is indeed the correct repo, just the "Area: Artifacts" label was not.

[KonstantinTyukalov]

Thanks for the reporting! We are working on higher priority issues now, but we'll get back to this one soon

[Varorbc]
