I am not saying the functionality is useless, but it already exists in other languages. Why force C# to look and behave like F# instead of just using F#?
I think most of the people creating and using these libraries would use F# if they could sadly. (However I am one of the lucky ones doing clojure in my day job.) Also a lot of existing software that needs to be maintained in C# would benefit from this library or others like it, just like they would benefit from having tools like linq, immutable collections, tpl available.
