I have been playing with creating little windows forms apps without visual studio.

I create my source in Notepad++ and compile with a NAnt build file.

When I run the application a command window is also displayed as well as the application window. How can I prevent the command window showing up?

using System;
using System.Drawing;
using System.Windows.Forms;
using System.Media;
using System.IO;

namespace mynamespace
{
    class MyForm : Form
    {   
        public Button btnPlay;

        MyForm()
        {
            this.SuspendLayout();

            this.Text = "My Application";

            InitialiseForm();       

            this.ResumeLayout(false);
        }

        private void InitialiseForm()
        {
            btnPlay = new Button();
            btnPlay.Location = new System.Drawing.Point(30,40);
            btnPlay.Text = "Play";
            btnPlay.Click += new System.EventHandler(btnPlay_Click);

            this.Controls.Add(btnPlay);
        }

        protected void btnPlay_Click(object sender, EventArgs e)
        {
            string wav = "testing123.wav";
            Stream resourceStream = System.Reflection.Assembly.GetExecutingAssembly().GetManifestResourceStream(wav);
            SoundPlayer player = new SoundPlayer(resourceStream);
            player.Play();  
        }

        public static void Main()
        {
            Application.Run(new MyForm());
        }
    }   
}
