title: 'System.Web.Mvc.HtmlHelper' does not contain a definition for 'RenderPartial' - ASP.Net MVC
body: <p>I've been trying to run ASP.Net MVC 1.0 on one machine, but can't get past this.  I create a new MVC project (C#).  It creates all the folders, views, controllers, models etc. All good.  Then, when I hit F5, I get the following:</p>
  
  <p>d:\VSCode2008\MVC\MvcApplication1\Views\Shared\Site.Master(19): error CS0117: 'System.Web.Mvc.HtmlHelper' does not contain a definition for 'RenderPartial'</p>
  
  <p>this happens at the following line:</p>
  
  <p>httpHandler.ProcessRequest(HttpContext.Current); in <strong>Default.aspx.cs</strong></p>
  
  <p>It seems when it is trying to do a RenderPartial() to render the logon partial.</p>
  
  <p>I have version 3.51 of .Net framework installed.  I installed version 1.0 of MVC, and the assembly clearly has RenderPartial() as extension methods of HtmlHelper.  </p>
  
  <p>Anyone seen anything similar?  I have found some posts about similar problems with betas and RCs but the suggested fixes have not woredk.</p>
  
  <p>I am loving the theory of MVC but it is not letting me play!</p>
