C# is a decent language, as is F#. But their success is the droves of labor contributed by MS. In some ways it is large and not easy to integrate into a distro and forms another isolated compiler base (need C# to compile C#) that is difficult to audit. Interesting is that they've adopted some of the lessons learned from Rust, or are trying to.
