Functions in C# aren't really first class. A static method for example isn't a Func< > or an Action< > and neither are normal methods, both of which are prevalent. To say that C# has first class functions is a misnomer. And on anonymous methods (delegates), Func< > and Action< >, that there's even a difference between the 3 shows C#'s age and some of its quirks. > now tuples and pattern matching in C# 7 Note the pattern matching in C# is a far cry from what you get normally in FP languages. First of all C# does not have ADTs, which means it cannot do exhaustiveness checking, making pattern matching only a superficial syntactic sugar. Tuples are nice though. > academic functional programming world and presented them in a nice 'friendly' form This is sort of a marketing myth. C# is not an FP language and I rarely see actual FP built in C# (same goes for Java). In my opinion you should try out the languages in the "academic functional programming world". Because you'll then notice that C#'s way of doing things is not "friendly", unless by that you mean half baked and annoying ;-)
