Description

The runner image in our CI is being updated to 20240126.1.0, and has introduced an unexpected change in behavior from the previous version 20240122.3.0.

Quotes are being included and escaped where they weren't before, with no changes except for the runner image being updated.

The code which generates the command being run is found here, and does not behave consistently between these two runner images.

No failure under runner image 20240122.3.0: https://github.com/CommunityToolkit/Windows/actions/runs/7716461243/job/21033317974?pr=328

Repro steps

Should be reproducible by invoking a PowerShell command built similar to this:

$cmd = 'dotnet'
$arguments = @(
    $sdkoptions
    'tool'
    'run'
    'slngen'
    '-o'
    $generatedSolutionFilePath
    $slngenConfig
    $diagnostics
    '--platform'
    $platforms
    $projects
)

Write-Output "Running Command: $cmd $arguments"

&$cmd @arguments
