I want to start powershell.exe with a scriptblock like this (it's working fine):

Start-Process powershell.exe {
  Get-Help 
  Get-Process
}

But this script doesn't work:

Start-Process powershell.exe {
  $string = "123xAbcxEFG"
  $split1,$split2,$split3 = $string.Split("x")
  Write-Output $split1
  Write-Output $split2
  Write-Output $split3
  sleep 10
}

I think I need Add-Type -AssemblyName "SomeNameSpace", but how can I find that namespace? Any intellisense or something like this?

The problem is with the quotes. It works, if you e.g. put additional single quotes around your double quotes. It also works with triple double quotes.

Start-Process powershell.exe  {
$string = """123xAbcxEFG"""
$split1,$split2,$split3 = $string.split("""x""")
Write-Output $split1
Write-Output $split2
Write-Output $split3
sleep 10
}

How I changed your code to catch the error (without the additional double quotes):

$ScriptBlock = {
  $string = "123xAbcxEFG"
  $split1,$split2,$split3 = $string.split("x")
  Write-Output $split1
  Write-Output $split2
  Write-Output $split3
  sleep 10
}

Start-Process powershell -argumentlist "-noexit -command $ScriptBlock"

    I changed my answer, because there are several ways. I also updated how I found the problem. – A189198 Oct 03 '16 at 10:27

    see my changed answer with the triple double quotes. – A189198 Oct 03 '16 at 10:29

    yes, because this error gives you a hint that the quotes are not working as you did expect. – A189198 Oct 03 '16 at 10:29
