Writing HTML Helpers
page 330,
book Professional ASP.NET MVC 3

For example in: \MvcApplication1\MvcApplication1\Core\Extensions.cs write something like:

using System;
using System.IO;
using System.Web.Mvc;

namespace MvcApplication1.Core
{
    public static class HtmlExtensions
    {
        private class Extensions : IDisposable
        {
            private readonly TextWriter _writer;

            public Extensions(TextWriter writer)
            {
                _writer = writer;
            }

            public void Dispose()
            {
                _writer.Write("</table>");
            }
        } //private class Extensions : IDisposable

        //note that this part is not under private class Extensions : IDisposable
        public static IDisposable Begin(this HtmlHelper html)
        {
            var writer = html.ViewContext.Writer;
            writer.Write("<table>");
            return new Extensions(writer);
        }
    }
}

And in: \MvcApplication1\MvcApplication1\Views\Stanko\Index.cshtml Something like:

@using (Html.Begin())
{
}

after starting app in the HTML source I will see tag <table></table> from here

In Global.asax.cs RegisterRoutes change to:

public static void RegisterRoutes(RouteCollection routes)
{
	routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
	
	routes.MapRoute(
		"Default", // Route name
		"{controller}/{action}/{id}", // URL with parameters
		new { controller = "Default1", action = "Index", id = UrlParameter.Optional } // Parameter defaults
	);

}

This mean that Default1 controller will be called, action Index (also view)... It is called from:

protected void Application_Start()

and Application_Start() is place where application begans

If your model look something like:

using System; 
using System.Data.Entity; 
using System.ComponentModel.DataAnnotations; 
using System.Data.Entity.Infrastructure;

namespace MvcApplication3.Models
{
    public class MyTable
    {
        [Key]
        public int MyNum { get; set; }
        public string Name { get; set; }
    }

    public class MyTableDBContext : DbContext
    {
        public DbSet MyTable { get; set; }
    }
}

Then, your connection string in Web.config must look like:

 <add name="MyTableDBContext" connectionString="Data Source=MyPC;
													Initial Catalog=MyDb;
													Integrated Security=False;
													Persist Security Info=True;
													User ID=myUser;
													Password=myPass" 
		 providerName="System.Data.SqlClient" />

Note that MyTableDBContext is in connection string and defined as DbContext in the model, and Integrated Security is false (true means to Windows Authentication)
