There's F# if you want to go fully functional. Why C# doesn't have first class functions and can't go fully functional (and likely never will): Scala tried and its compiler is slow, even after so many iterations and new novel compiler ideas. I like the way it is, and hope it doesn't change. Unless they could make this possible without making the compile process extremely slow.
