Along those lines, a great trick for Go on Windows is to set your $GOPATH outside of the WSL filesystem, so you're developing in, e.g. /mnt/c/. This gives you full access in both Windows and Linux to your Go project, so if you need to open a file in Photoshop, etc. it's painless.

I seem to miss the point why this is huge. Why can't the project compiled for Windows in first place? Are there System specific calls?
