Powershell output is being hidden.
I am trying to execute the following command:
$dotnetef = Start-Process -FilePath "dotnet.exe" -ArgumentList "ef database update -c $($env:DBCONTEXT)" -WorkingDirectory $WorkingDir -NoNewWindow -wait -PassThru
This command works most of the time. However sometimes it fails, and I would like to see the output of dotnet.exe to find out why. The ci.appveyor.com console screen does not show the output of this command. No matter how I redirect it, it is hidden.
In my local environments both PS5.1 and PS7+ show the outputs of dotnet.exe as long as I have "-NoNewWindow" enabled on Start-Process (which I do).
Why is this PS behavior different in appveyor and why am I unable to redirect it so it is visible?

StdOut/StdErr redirection doesn't work the same way as in Windows console and when catching the output programmatically. In Windows the API for collecting process output is very limited (compared to Linux/macOS).
You can use this helper method using

That looks good! Is that function available to run by default, or do I need to load that "common.ps1" script first?

You need to copy it to your scripts.
