I wrote a hook for integrating with the pre-commit project. It's here: https://github.com/jvstein/pre-commit-dotnet-format

I've been using it while developing on Linux, but haven't tested it on Windows or macOS. It's very much dependent on Docker, using a prebuilt docker image, because pre-commit doesn't support C# yet. I'd be very happy to integrate it into the project, but wasn't sure how to go about adding the docker dependency to the build system.
