That is correct, the subject line anyway.Majority of enterprises still use Windows, email is on exchange, Microsoft office is the defacto app, vizio is your tool for diagrams, excel is what the business loves and uses. Yet a lot of developers love and want linux. As in my case, I like to think of myself as an above average software engineer. I would love to use Linux at work, I did for a while, soon Pidgin is a half baked replacement for Lync, Evolution almost works as a email client and even though Libre Office sort of opens Word document, it does make the document formatting useless, so is not of much use, if we didn't want formatting, we would use text files. Yet platform for production is Linux, our team looks after enterprise front office web apps for our institution.
So all of us do development on Windows, we would love Linux if the entire bank switched, good luck with that.
So then this WSL fills that gap for me. I don't need to shell into any linux machine, have cygwin sitting along. I can just install windows. Now yes I can use something like virtualbox, however some parts of our application also run on Docker. so I need both Linux and Docker, and if you have tried, the way Windows Hyper-V works, you cannot run it along with Virtualbox. For the moment, we choose mixed bag, a seperate linux VM on our company cloud, or VMs on Hyper-V. It would speed things up if can just get a distro going right off the store.
Having said that, the value is incremental, as is we can install VMs via Hyper-V and it works more or less.
