A couple of features of PowerShell v6 release candidate 2 need commenting on.
Firstly, I was surprised when installing RC 2 on a Windows 10 machine (Insider build) that RC1 was removed. In the past you’ve been able to run numerous versions of PowerShell v6 side-by-side. This has consequences if the behaviour continues into the GA version and the 6.1 alpha/beta releases as you’ll have to choose between the stable, production version and the changeable new version.
Secondly, and this one was publicised by the PowerShell team, Pester is no longer installed by default with PowerShell v6. You can download the latest version of Pester from the PowerShell gallery. Not sure on thinking behind this decision but the download is easy so it’s not a deal breaker –you just have to remember to do it. May be best to use Save-Module for the download so you don’t have to perform the download if a new version of PowerShell v6 becomes available and overwrites the current version.
Next job is to install the OpenSSH optional feature and see how that goes. Be very interested to see if and how its updated as new versions of the Windows Insider builds are released.
