Awesome
This repo is currently out of date, but has a new release with new features.
Otherwise be aware that this now houses a new release with some additional U# features which is somewhat jank and I don't advise you use it if you're looking at distributing prefabs. Go to the release link here if you are still interested https://github.com/MerlinVR/UdonSharp/releases/tag/v1.2.0-b1
