Could you please also fix this line? The short form -v does not work, because PowerShell binds it to the $vs parameter instead of $properties.

runtime/eng/build.ps1

Line 29 in 08e0445

Write-Host " -verbosity MSBuild verbosity: q[uiet], m[inimal], n[ormal], d[etailed], and diag[nostic] (short: -v)"

Thanks, I decided to instead fix the -v alias.
