c# to f# - Parameterless lambda expressions in F# -

i looking way define parameterless lambda expressions in f#, much next c# example.

var task = () => { int x = 3; dosomething(x); }

i tried following

let task = fun _ -> allow x = 3 dosomething x

it compiles gives me task : ('a -> unit) looking task : (unit -> unit)

the msdn documentation not talk this. missing here ?

it's just

let task = fun () -> // whatever need

you illustration be:

let task = fun () -> allow x = 3 dosomething(3)

assuming dosomething of type int -> unit - if returns else need

let task = fun () -> allow x = 3 dosomething(3) |> ignore

to type unit -> unit

remark: don't write let task = fun () -> ... let task() = ...

the thing missed: if write fun _ -> () saying want take parameter don't mind - f# take general (being named 'a here) - include unit! () value of type unit (more or less void c# ... true type in f#)
