Little help anyone?

I have just tried this code in my Console Application and it worked:

using System.Management.Automation.Runspaces;
using Microsoft.PowerShell;

namespace TryConsoleShell
{
    class Program
    {
        static void Main(string[] args)
        {
            var config = RunspaceConfiguration.Create();
            ConsoleShell.Start(config, "Windows PowerShell", "help text", new string[] { "-noexit", "ls" });
        }
    }
}

I guess your application is Windows Application and this scenario is either not supported at all or you still have to have a console window available (I have not tried this way yet).

EDIT:

It worked in WinForm Application as well. But the console window is still needed for the console host. To make the console window available just change the project output type to Console Application.

using System;
using System.Management.Automation.Runspaces;
using System.Windows.Forms;
using Microsoft.PowerShell;

namespace WindowsFormsApplication1
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            var config = RunspaceConfiguration.Create();
            ConsoleShell.Start(config, "Windows PowerShell", "help text", new string[] { "-noexit", "ls" });
        }
    }
}

P.S. I have never seen use of this scenario in practice and did not even know that it actually works. Are there some practically useful applications of it?
