I'm observing F#'s Map is always ordered based on its keys. Does F# provide any alternative to an ordered dictionary?
I wanted to ask before using a C# Dictionary as an alternative.

f:x↦y means that f is a function which takes in a value x and gives out y.
more ... A special relationship where each input has a single output. It is often written as "f(x)" where x is the input value. Example: f(x) = x/2 ("f of x equals x divided by 2")
Given a function f, the derivative f' can be used to get important information about f. For instance, f is increasing when f'>0. The second derivative gives useful concavity information.
FSharpx.Collections has the PersistentHashMap, which isn't ordered.
