I was working with Azure PowerShell and suddenly I started getting an error of “‘VS2015’ was not found” every time I ran Get-AzureWebsite for one of my sites. All of my other sites were fine.
I did some searching and I found a couple of blog posts that pointed me to remote debugging being on. I turned it off but I was still getting the error. After much fumbling around, I went back to Remote debugging, and turned it on, but for Remote Visual Studio version of 2013. And my PowerShell started working again!
I was then able to turn it off again and my script was still working. I assume that my site got stuck in a weird state, but toggling this setting made it all work again.
Remote debugging will stay enabled for 48 hours if you don’t turn it off.
