title: Umbraco MVC build error - Collection.cshtml - 'System.Web.WebPages.Html.HtmlHelper' does not contain a definition for 'ViewData' or 'EditorFor'
body: <p>I am getting a build error for an Umbraco MVC website:</p>
  
  <p>'System.Web.WebPages.Html.HtmlHelper' does not contain a definition for 'ViewData'
  'System.Web.WebPages.Html.HtmlHelper' does not contain a definition for 'EditorFor'</p>
  
  <p>The error relates to a file in the packages folder:</p>
  
  <p>....\packages\BeginCollectionItem.1.2.1.0\content\Views\Shared\EditorTemplates\Collection.cshtml</p>
  
  <p>I can add the web.config file in the Views folder in there, which resolves this particular issue, but then starts complaining about a missing reference to 'Orchard', and I am concerned that I am just masking a deeper issue.</p>
  
  <p>Has anyone come across this before?  If so, how was it resolved?</p>
