Symlink from WSL to Windows

Frank Schmidt -
  1. first open Powershell with Run as Administrator
  2. then run
 New-Item -ItemType SymbolicLink -Path "windows-path\to\symlink" -Target "\\wsl$\Ubuntu\home\yourusername\path\to\target-thing"

substitute your distro name for Ubuntu above if necessary, and yourusername obviously too.

I used this to help manage my dot-files. I keep all my configurations in a git-controlled repo in WSL, but sometimes I want to use those config files for a Windows app. So rather than cloning the repo twice, I can use a symlink.
