令我惊讶的是,所有进程都在同一个线程上完成.根本就没有并行性.

open System
open System.Threading
open System.Threading.Tasks


let doWork (num:int) (taskId:int) : unit =

[<EntryPoint>]
let main argv = 

    let t2 = Task.Factory.StartNew(fun() -> doWork 10 2)
    //printfn "launched t2"
    Console.WriteLine("launched t2")
    let t1 = Task.Factory.StartNew(fun() -> doWork 8 1)
    Console.WriteLine("launched t1")
    let t3 = Task.Factory.StartNew(fun() -> doWork 10 3)
    Console.WriteLine("launched …

你能解释一下我之间的区别吗？
