Question

I am attempting to deploy a simple f# console app to a coworkers computer but it keeps failing. After double clicking on the app icon, the console window appears but then the Microsoft error reporting window shows up asking if I would like to send the error report, I decline then some text flashes in the console window. It looks like an error message, but the window closes too fast to tell. The weird thing is, if I create a similar C# app, it works. I am targeting .net 4 client framework in release mode.

Here is the code

f# code (doesn’t work):

open System

printfn "print test"
Console.ReadLine() |> ignore

c# code (does work):

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace TestCApplication
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("Testing...");
            Console.ReadLine();
        }
    }
}

Look at the references of your F# project and you will see one to FSharp.Core which is normally located here:

C:\Program Files (x86)\Reference Assemblies\Microsoft\FSharp\2.0\Runtime\v4.0\FSharp.Core.dll

On Windows 7 (64 bit) PC

Also look at the F# site to get the runtime download.

EDIT: here is the direct link to the runtime download (thanks ildjarn):
