Yes, you are right, F# has been open-source and on github for a while, and that itself isn't new news. However I don't believe users could make contributions that would be upstreamed into the official releases or VS builds. Quoting from the associated blogpost - http://blogs.msdn.com/b/fsharpteam/archive/2014/04/03/facilitating-open-contributions-for-the-f-compiler-library-and-visual-f-tools.aspx http://blogs.msdn.com/b/fsharpteam/archive/2014/04/03/facili... "Prior to today, contributions were not accepted to the core implementation of the F# language. From today, we are enabling the community to contribute to the F# language, library and tools, and to the Visual F# Tools themselves, while maintaining the integrity and unity of the F# language itself."
