My Simple Indigo Service

Now onto some real infocard work. To begin with, I developed a simple webservice and client using Indigo. This service basically displays the raw SOAP which it is sent:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;

//This is the Indigo namespace
using System.ServiceModel;
using System.Xml;

namespace InfoCardService
{
    /**
    Here, I'm using an interface to define the service contract.  
    Service contracts are explicit in Indigo, and can be distict
    from application/class level contract as seen here.
    */
    [ServiceContract]
    interface ISimpleService
    {
        //A very raw service - interface accepts low level message type.
        [OperationContract(IsOneWay = true)]
        void Receive(System.ServiceModel.Message msg);
    }


    public partial class SimpleService : Form, ISimpleService
    {
        //selfhosting ServiceHost using generics to be types to my implementation
        ServiceHost sh;
        
        public SimpleService()
        {
            InitializeComponent();            
        }

        private void button2_Click(object sender, EventArgs e)
        {
            sh.Close(); 
            Application.Exit();
        }

        public void Receive(System.ServiceModel.Message msg)
        {
            MessageBox.Show("New Message:\n\n" + msg.ToString());            
        }

        private void Start()
        {
            sh = new ServiceHost();
            sh.Open();
        }

        static void Main(string[] args)
        {
            SimpleService service = new SimpleService();
            service.Start();
            Application.EnableVisualStyles();
            Application.Run(service);
        }

    }
}
