Releated to NuGet issue #8806

PackageFiles
    build\A.Some.Props.File.props
        BuildAction = None
        Link = build\A.Some.Props.File.props
        Pack = true
        PackagePath = build/
    build\Package.props.default
        BuildAction = None
        Link = build\NU5129.Build.Props.Problem.props
        Pack = true
        PackagePath = build/NU5129.Build.Props.Problem.props
