Unable to attach to ASP.NET process...?

Hi, I have the book "Programming in C#" and I am learning about ASP.NET right now. I am working on a webform example in the book and it says to install IIS and FP Server Extensions. I have installed IIS v5.1 and the front page server extensions, however when I run my code (typed verbatim from the book) it starts an Internet Explorer page with URL:http://localhost/WebForm1/HelloWeb.aspx and displays nothing then I get an error message box stating "Unable to attach to ASP.NET process (typically aspnet_wp.exe)"

I am a definite newbie with all of this and was wondering why I can't seem to get ASP.NET or webforms to work properly.

Here is the code I have in Borland C# Builder (Although a simple webform with hello world and a <% %> time statement also fails):

PHP Code:


		
			
 using System;

using System.Collections;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.Web;

using System.Web.SessionState;

using System.Web.UI;

using System.Web.UI.WebControls;

using System.Web.UI.HtmlControls;



namespace WebForm1

{

    /// <summary>

    /// Summary description for WebForm1.

    /// </summary>



    public class WebForm1 : System.Web.UI.Page

    {

        // Data members used for initializing page_load with

        // data from database.

        private System.Data.SqlClient.SqlConnection myConnection;

        private System.Data.DataSet myDataSet;

        private System.Data.SqlClient.SqlCommand myCommand;

        private System.Data.SqlClient.SqlDataAdapter dataAdapter;



        protected System.Web.UI.WebControls.RadioButtonList rbl1;

        private void Page_Load(object sender, System.EventArgs e)

        {

            // Put user code to initialize the page here

            if(!IsPostBack)

            {

                string connectionString = "server=(local)\\NetSDK;" +

                    "Trusted_Connection=yes; database=northwind";

                myConnection = new System.Data.SqlClient.SqlConnection(

                    connectionString);

                myConnection.Open();



                // Create the dataset and set Case Sensitive Property

                myDataSet = new System.Data.DataSet();

                myDataSet.CaseSensitive = true;



                // Create the SqlCommand onject and assign the

                // connection and the select statement

                myCommand = new System.Data.SqlClient.SqlCommand();

                myCommand.Connection = myConnection;

                myCommand.CommandText = "SELECT ShipperID, CompanyName FROM Shippers";



                // create the dataAdapter object and pass in the

                // SqlCommand object and establish the data mappings

                dataAdapter = new System.Data.SqlClient.SqlDataAdapter();

                dataAdapter.SelectCommand=myCommand;

                dataAdapter.TableMappings.Add("Table", "Shippers");

                dataAdapter.Fill(myDataSet);



                // Set up the properties for the rbl1

                rbl1.RepeatLayout =

                    System.Web.UI.WebControls.RepeatLayout.Flow;

                rbl1.DataTextField = "CompanyName";

                rbl1.DataValueField = "ShipperID";



                // Set the datasource and use default view of shippers table

                rbl1.DataSource = myDataSet.Tables["Shippers"].DefaultView;

                rbl1.DataBind();



                // Set one to be default selected

                rbl1.Items[0].Selected = true;

            }



        }



        #region Web Form Designer generated code

        override protected void OnInit(EventArgs e)

        {

            //

            // CODEGEN: This call is required by the ASP.NET Web Form Designer.

            //

            InitializeComponent();

            base.OnInit(e);

        }

        

        /// <summary>

        /// Required method for Designer support - do not modify

        /// the contents of this method with the code editor.

        /// </summary>

        private void InitializeComponent()

        {

            this.Load += new System.EventHandler(this.Page_Load);

        }

        #endregion

    }
