Creating a 2 steps expression based link

This is a simple post highliting how to build a quick extension to HtmlHelper.
You'll need to use the MVC Futures extensions

For the extension all you need is this

namespace Microsoft.Web.Mvc
{
 using System;
 using System.Collections.Generic;
 using System.Diagnostics.CodeAnalysis;
 using System.Linq.Expressions;
 using System.Web;
 using System.Web.Mvc;
 using System.Web.Mvc.Html;
 using System.Web.Routing;
 using Microsoft.Web.Mvc;
 public static class MyLinkExtensions
 {
  public static void BeginLink<TController>(this HtmlHelper helper,
   Expression<Action<TController>> action
   ) where TController : Controller
  {
   BeginLink(helper,
    action,
    new { });
  }
  public static void BeginLink<TController>(this HtmlHelper helper,
   Expression<Action<TController>> action,
   object htmlAttributes) where TController : Controller
  {
   BeginLink(helper,
    action,
     new RouteValueDictionary(htmlAttributes));
  }
  public static void BeginLink<TController>(this HtmlHelper helper,
   Expression<Action<TController>> action,
   IDictionary<string, object> htmlAttributes) where TController : Controller
  {
   TagBuilder builder = new TagBuilder("a");
   builder.MergeAttributes(htmlAttributes);
   string href = Microsoft.Web.Mvc.LinkExtensions.BuildUrlFromExpression(helper, action);
   builder.MergeAttribute("href", href);

   HttpResponseBase httpResponse = helper.ViewContext.HttpContext.Response;
   httpResponse.Write(builder.ToString(TagRenderMode.StartTag));

  }

  public static void EndLink(this HtmlHelper helper)
  {
   TagBuilder tagBuilder = new TagBuilder("a");
   HttpResponseBase httpResponse = helper.ViewContext.HttpContext.Response;
   httpResponse.Write(tagBuilder.ToString( TagRenderMode.EndTag));
  }
 }
}

And to use it, all you need is something like :

<% Html.BeginLink < HomeController >( c=> c.About() ); %>
Link text
<% Html.EndLink(); >

Note: Don't forget to add Microsoft.Web.Mvc to the namespaces that the view uses
