This below, is a Channel9 video which I enjoyed.

Since .NET Core and many of the tools for building .NET applications have been open sourced, community involvement in the ecosystem has increased tenfold.

In this episode, Avi Avni (@AviAvni3) joins Rich (@runfaster2000) to discuss his experience with contributing features to the CoreCLR and F# language code bases. He talks about what it’s like to work with the various teams on GitHub and also the importance of mentorship.
