Summary

We should warn users when they use the Restore target specifically (-t:Restore) instead of /restore during a build - this is very often a mistake and we should point users to the correct version.

Background and Motivation

Users of the new CLI-based MSBuild property/item syntax often run into issues with uninitialized repositories, so they add -t:Restore and then wonder why their tooling only works after the first run. This is the core reason, and we should guide them to using the switch.

Proposed Feature

When

• Restore is part of the targets list, and
• a project contains NuGet packages, and
• a nuget dependency file was created during the build
• then issue a warning so the user knows they should use /restore instead of /t:Restore
