PowerShell version incompatibilities

Posted by: | April 20, 2019 Comments Off on PowerShell version incompatibilities |

There are incompatibilities between Powershell versions – you can’t use classes in Windows PowerShell v4 and there are differences between Windows PowerShell v5.1 and v6.x. One way to deal with PowerShell version incompatibilities is described in the recent post from the PowerShell team – https://devblogs.microsoft.com/powershell/using-psscriptanalyzer-to-check-powershell-version-compatibility/


I’m not a big fan of tools such as PSScriptAnalyzer as I find them restrictive and they get in the way of doing what I need to do. Having said that the usage described in the article is actually very useful especially the way you can configure which PowerShell versions you need to be worried about.


PSScriptAnalyzer is built into VSCode so the availability of the functionality to chaeck PowerShell version incompatibilities actually strengthens the case for using VSCode (I still don’t feel 100% comfortable with it – mainly because it does too much for what I need. The ISE is simpler and suits my needs better).


If you need work round PowerShell version incompatibilities in the code you write this may be of great help.
