    8 Warning(s)

There are some warnings from arcade projects too - following up with them separately.

[dibarbet]

looks like warnings in the arcade project are actually coming from

roslyn/eng/Tools.props

Line 10 in 41e91ea

<PackageReference Include="Microsoft.DotNet.Build.Tasks.Feed" Version="$(MicrosoftDotNetBuildTasksFeedVersion)" />

The referenced issue has been resolved, so I have deleted that project which fixes the errors. Seems to build fine but want a second confirmation from @JoeRobich

Nice!

@dotnet/roslyn-compiler could use 1 more review for a small infra change :)
