Steps to reproduce
Below are two snippets demonstrating seemingly identical behavior, however the bottom snippet does not work.
# This Works
$VariableOutsideParallel = 'something'
1..1 | ForEach-Object -Parallel {
Write-Host $Using:VariableOutsideParallel
}# This does NOT on 7.2.0+ (But does on 7.1.*)
$VariableOutsideParallel = 'something'
[scriptblock]$SB = {
Write-Host $Using:VariableOutsideParallel
}
1..1 | ForEach-Object -Parallel $SBExpected behavior
PS> $VariableOutsideParallel = 'something'
PS> [scriptblock]$SB = {
Write-Host $Using:VariableOutsideParallel
}
PS> 1..1 | ForEach-Object -Parallel $SB
somethingActual behavior
