F# Console app (tried .NET 4.5 and 4.5.1). Chart seems to hang with Not Responding on Windows 8.1.

open FSharp.Charting
open System

[<EntryPoint>]
let main argv = 
    printfn "%A" argv
    
    Chart.Line([ for x in 0 .. 10 -> x, x*x ]).ShowChart()
    Console.ReadLine() |> ignore
    0 // return an integer exit code

hack, but works

   use form = new Form(Width=400, Height=300, Visible=true, Text="Hello charting")
   Chart.Line([for x in 0 ..10 -> x, x+x]).ShowChart()
   System.Windows.Forms.Application.Run(form)
