PowerShell 7 Remoting from Azure DevOps Pipeline - powershell-7.0

Question

We were using Azure DevOps Pipelines and PowerShell Remoting to execute PS1 scripts:
trigger: none
jobs:
- job: PSRemoting
timeoutInMinutes: 5760
pool:
name: 'DevOps-Agent2-VM'
steps:
- checkout: none
- task: PowerShellOnTargetMachines#3
displayName: 'PSRemoting'
inputs:
Machines: '$(VM-PublicIP)'
UserName: '$(VM-UserName)'
UserPassword: '$(VM-Password)'
InlineScript: |
. C:\Scripts\Test-Parallel.ps1
We have added -parallel feature that requires PowerShell 7 and our scripts are failing now:
2022-11-02T13:37:18.3246154Z ForEach-Object : Parameter set cannot be resolved using the specified named parameters.

Here is Test-Parallel.ps1:
$items = 1..100
$items | ForEach-Object -Parallel {
Write-Host "$(Get-Date) | Sleeping for 1 second..."
Start-Sleep 1
} -ThrottleLimit 10
How can we force PowerShell to run version 7 with our Azure DevOps Pipeline task?

Answer 1

Try this in your Test-Parallel.ps1 script:
workflow Test-PipelineDeploy {
$items = 1..100
foreach -parallel ($item in $items) {
Write-Host "$(Get-Date) | Sleeping for 1 second..."
Start-Sleep 1
} -ThrottleLimit 10
}
Then call Test-PipelineDeploy
