title: HttpContext.Current not Resolving in MVC 4 Project
body: <p>I am wanting to use ImageResizer (from ImageResizing dot net). I installed ImageResizer for MVC via NuGet. But when I go to use the following code from the example:</p>
  
  <pre><code>//Loop through each uploaded file
  foreach (string fileKey in HttpContext.Current.Request.Files.Keys)
  {
      HttpPostedFile file = HttpContext.Current.Request.Files[fileKey];
      if (file.ContentLength &lt;= 0) continue; //Skip unused file controls.
  
      //The resizing settings can specify any of 30 commands.. See http://imageresizing.net for details.
      //Destination paths can have variables like &lt;guid&gt; and &lt;ext&gt;, or 
      //even a santizied version of the original filename, like &lt;filename:A-Za-z0-9&gt;
      ImageResizer.ImageJob i = new ImageResizer.ImageJob(file, "~/uploads/&lt;guid&gt;.&lt;ext&gt;", new ImageResizer.ResizeSettings(
                              "width=2000;height=2000;format=jpg;mode=max"));
      i.CreateParentDirectory = true; //Auto-create the uploads directory.
      i.Build();
  }
  </code></pre>
  
  <p>The "HttpContext.Current.Request.Files.Keys" in the foreach is not resolving? I have my usings correct and Visual Studio offers no "Resolve" options.</p>
