I sometimes get asked for suggestions for a Powershell editor. Probably the biggest and best is Sapiens Primalscript. But with all the abilities and power; this means a bigger price tag. There is also an expectation of upgrades. I let mine go too long and was told I had to purchase new. 😦
I also find many people are looking for a free editor. Microsoft has a page of suggested editors on Technet.
As mentioned I have used Primalscript and recommend it if you have the money to invest.
I have used the one that comes with Powershell and it’s ok if you are starting out.
I have used the GUI version and found it’s ok for most things.
I am now starting to “play around” with Admin Script Editor. The page shows it’s a purchased package but this is no longer the case. The company closed shop but they made the last version free to people who use the itninja site.
