Just host the code in Windows-land.

Symlink ~/code to /mnt/c/Users/jamie/code, run whatever editor I want in windows to edit the code, and run my app from linux-land in the console. Hasn't given me a hiccup yet, even with a local sqlite database and such.

If you just treat your linux homedir as a spot for dotfiles and symlinks out to windows, it shouldn't give you much trouble unless you're doing stuff that relies heavily on owner/write permissions.

Or write it using whichever editor you'd prefer in Windows, then access it from WSL, I guess? You can see the entire Windows filesystem from inside the Linux environment. You just shouldn't try to write to the locations that they keep the Linux part of the filesystem in from Windows.

I'd use Emacs and the same X11 apps I'd use on a Linux cluster. There are X servers for Windows, though WSL strangely omits one.

If you like Windows apps, why run WSL?
