Microsoft touting WSL is an attempt to steal market share from actual Linux. It’s designed to make people think “if Windows does everything Linux can, why do I even need Linux?”, thereby feeding Microsoft licensing money, market control, and the user’s data. It’s not a move with computer users’ nor the free software ecosystem’s best interests in mind.
The company I work with at the moment are tied to ASP.NET so there little to no hope of migrating back to a Linux distro. There’s talk of a .NET core upgrade but talk is cheap.
Have they considered Mono?
