From a language design standpoint, it's kinda damning... Since it's launch C# has reversed itself on fundamental language decisions and requirements to go ever closer towards F#s capabilities. Unfortunately, thanks to F#s functional heritage and compiler, there are huge swaths of capabilities that can't be completely realized by C#. That leads to "almost but not quite" convenience features in C#, without any of the reductions of cognitive load or any of the systematic guarantees you get with a functional language. C# is easily one of the best languages out there, but it's also accumulating a lot of ways to skin various cats.
