I try execute the following command from VSCODE:

# Outputs to the console 
Write-Host "This is a log message." | Out-File -FilePath "C:\Logs\HostOutput.log" -Append

I don't get none result in the file.

The file is empty.

What happen?

I use VSCODE administrator mode.

    Use Add-Content.

    "This is a log message." | Add-Content "C:\Logs\HstOutput.log" -PassThru

    Note: -PassThru so the log message is output to the console.

    Documentation says that Write-Host is to produce display-only output, and you can use these alternatives:

    Write-Host "This is a log message." 6>> "C:\Logs\HostOutput.log"

    or

    Write-Output "This is a log message." | Out-File -FilePath "C:\Logs\HostOutput.log" -Append
