How to use Powershell 7 instead of Powershell 5?

[InfospyPT]

Hello,

I have a task that I need to run under Powershell 7 instead of Powershell 5.

On the task.json file I have the following Execution definition:

"execution": {
"PowerShell3": {
"target": "task.ps1",
"workingDirectory": "$(currentDirectory)",
"argumentFormat": ""
}

The task runs correctly on the Agent server but it runs on Powershell 5, how (if possible) can I run it on Powershell 7?

No, the PowerShell handler uses PowerShell 5, unfortunately.

You can call & pwsh script.ps1 from the entry point though... Or call PowerShell core from a node task. Check out the official PowerShell task to see how Microsoft does that.

If I understood correctly, it loads pwsh.exe (7.x) from powershell.exe(5.1) and then runs the script in pwsh.exe.

Yeah and it has a fallback scenario where it runs pwsh.exe from Node on Linux and Mac.

add pwsh: true to the inputs.

- task: PowerShell@2
  displayName:  RunWithPs7
  inputs:
    pwsh: true
