title: The controller for path '/' was not found or does not implement IController in Sitecore
body: <p>I am learning Controller rendering in Sitecore from <a href="https://www.youtube.com/watch?v=i3Mwcphtz4w" rel="noreferrer">Here</a> .</p>
  
  <p>I created One simple controller(HelloWorld) and Related View(Index.schtml) . Mapped it(with Name PageContent) in rendering section of Sitecore Explorer... and Add Rendering Item in Home Item in Content Section of Sitecore Explorer.. But When I Browse it, it gives the Error .</p>
  
  <pre><code>The controller for path '/' was not found or does not implement IController. 
  </code></pre>
  
  <p>All the post I have Read are related to Asp .Net MVC ..but I have issue related to Sitecore MVC</p>
  
  <p>Sample.html (Page Content in Sitecore Explorer Rendering Section)</p>
  
  <pre><code>@using Sitecore.Mvc
  
  &lt;html&gt;
  &lt;body&gt;
      @Html.Sitecore().Placeholder("content")
  
      &lt;p&gt;Today's date is @DateTime.Now.ToShortDateString()&lt;/p&gt;
  &lt;/body&gt;
  
  &lt;/html&gt;
  </code></pre>
  
  <p>Only this Line is giving Problem </p>
  
  <pre><code>@Html.Sitecore().Placeholder("content")
  </code></pre>
  
  <p>If I remove this line ...It Works fine and page on Browser show date and time</p>
  
  <p>Index.html</p>
  
  <pre><code>&lt;p&gt;Hello from Controller -todays Date is @DateTime.Now.ToString()&lt;/p&gt;
  </code></pre>
  
  <p>Controller</p>
  
  <pre><code>using System;
  using System.Collections.Generic;
  using System.Linq;
  using System.Web;
  using System.Web.Mvc;
  
  namespace MVC.Controllers
  {
      public class HelloWorldController : Controller
      {
          //
          // GET: /HellowWorld/
  
          public ActionResult Index()
          {
              return View();
          }
  
      }
  }
  </code></pre>
