A few days ago I created a repository on Github, then followed the steps to add my existing solution to it. I have no idea what I did wrong, but after a few random 'git add' commands and whatnot, I now get the message in github for windows:
failed to sync this branch.
You might need to open a shell and debug the state of this repo.
Git stores everything about a repo at the repo's root in the hidden
.git folder. Simply deleting that folder,
rm -rf .git makes it as if there never was a repo there.
