The “F# Core Engineering Group” is a loose term for the people who maintain and contribute to the repositories of The F# Software Foundation. There are no “meetings”, all work is coordinated via github issues.

These people - both maintainers and contributors - work cooperatively with major industrial and community contributors to F# to facilitate open-source contributions to the F# core components. For example:

The vim-fsharp, emacs-mode-fsharp, sublime-fsharp-package and FAKE repositories are here for historical reasons, they are not considered to be FSSF repositories.

Please join in the fun!
