This is just a small post to help my ageing memory remember where things are located.

• Powershell C#
  Locate the dll, System.Management.Automation.dll, and add it to your project, (or add it via Nuget).
  • See this blog for a good introduction on creating a project, (works for vs2015).
• Check what version is installed
  • According to the official site you need to check the registry
    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PowerShell\1
    or
    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PowerShell\3
    And check that the value Install is set to ‘1’.
• Debuging
  • The external program is C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe
  • But the actual location is:
    • Powershell 1: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PowerShell\1\PowerShellEngine\{ApplicationBase}
    • Powershell 3:HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PowerShell\3\PowerShellEngine\{ApplicationBase}
  • Launching from debuger:
    • For a script:
      PowerShell -Command “& {.\myscript.ps1}” or
      PowerShell -File “.\myscript.ps1”
    • For a CmdLet/Module:
      -noexit -command “&{ import-module .\AMPowerShellCmdLets.dll -Verbose}”
• Some links
  • The ‘official’ powershell blog/site
