Does .NET and its family have functional paradigm as feature rich as Haskell, Ocaml or Scala?

I just don't understand the appalling attention given to F#. Is C# doing good in that regard?

I would say that one of the main reasons why F# gets comparatively little attention is that, yes, C# is being evolved with a fairly big focus on taking lessons from functional languages. Pattern matching is coming along (though it will probably never be as powerful/expressive as in e.g. F#), C# 8 will have nullable reference types, essentially providing null safety in the same way as Option, immutability is being touted as a Good Thing (I hope record types will be with us soon), etc. As someone who loves functional programming, C# is without a doubt my favorite not-mainly-functional-language (and it's way up there overall).

Compare this with Java and the functional JVM languages, where Java didn't even have lambdas until fairly recently - no wonder a (relatively) large subset of JVM developers focus on Scala and Clojure.
