All I know is that the WSL is a massive step-up from Cygwin or Mingw32. We’ve been here before. The most recent incarnation before WSL was a klunky VirtualBox VM steered by Packer. The idea that you can mash a few buttons and get an Ubuntu VM with filesystem mapping that “just works” is a huge improvement.
Edit: I really don’t get the vitriol anyone gets for using the WSL when it’s a problem the FOSS community has tried to solve three times over in the last 25+ years or so.
I’ve used both. What I can tell you is that moving to WSL is like moving to Linux wholesale. Treat it like porting your toolchain.
IIRC, MinGW tools will happily take windows style paths (e.g. “C:\Users~myuser\projects”). If your tooling/scripting depends on being able to use Windows style paths, you’ll have to fix that first or you’re going to have a really bad time. There may be other small differences between MinGW tools and what ships on Ubuntu (or whatever Linux you decide to use in the WSL).
