On a Windows Server 2003 rig (which already has .NET 4 but no 4.5 on it) that is to be expired before the end of the year, I'd like to run a few PowerShell 3 scripts on a scheduled base as the scripts depend on functionality introduced in PowerShell 3.
There are not many useful hits in the search I tried as they give mixed information: Some indicate it is possible but others indicate impossible and it certainly is not in the official downloads.
So:
- Are there workarounds to install PowerShell 3 on Windows Server 2003?
- If not, where should I look for replacement Cmdlets that are unique to PowerShell 3 like Invoke-RestMethod, ConvertTo-Json, ConvertFrom-Json or Invoke-WebRequest?
