Question

Answer 1

You can do it:

[<AutoOpen>]
module Globals =
  let map = System.Collections.Generic.Dictionary<_,_>()

Then use it unskilled throughout the program:

map.Add(1, "a")
map.Add(2, "b")
map |> Seq.iter (fun (KeyValue(k, v)) -> printfn "Key: %d, Value: %s" k v)

Answer 2

depending on which project you are doing in the best way, maybe just declare it in a module:

module GlobalVals =

    let myCollection = .... // whatever

you can just use it with

GlobalVals.myCollection...
