  Hi,
  
  I've some trouble using any asp.net MVC 3 components in my views.
  
  When I try, I got this kind of exception :
  

  Compiler Error Message: CS1061: 'System.Web.Mvc.HtmlHelper<VVVV.XXX.YYY.WWW.ZZZ.Areas.Advertiser.Models.AdsListModel>' does not contain a definition for 'Telerik' and no extension method 'Telerik' accepting a first argument of type 'System.Web.Mvc.HtmlHelper<VVVV.XXX.YYY.WWW.ZZZ.Areas.Advertiser.Models.AdsListModel>' could be found (are you missing a using directive or an assembly reference?)

  
  I'm only trying to display this:
  
  

  @(Html.Telerik().PanelBar()

         .Name("PanelBar")

         .Items(items =>

         {

             items.Add().Text("Item 1");

                         

             items.Add().Text("Item 2")

                  .Items(subItems =>

                        {

                            subItems.Add().Text("Sub Item 1");

                            subItems.Add().Text("Sub Item 2");

                            subItems.Add().Text("Sub Item 3");

                        });

         })

         .Render())

  
  
  In one view of one of my area.
  
  What is going wrong? 
  
  I've also one instruction in the layout(for script/css registration), which doesn't seems to make any trouble.
  
  Is this a problem with area?

  I added the namespace declaration in the web.config file of the area,it seems it helped, but I'm still blocked:
  
  With this error this time: 
  
  CS1502: The best overloaded method match for 'System.Web.WebPages.WebPageExecutingBase.Write(System.Web.WebPages.HelperResult)' has some invalid arguments

  Hello Julien,
  
  You need to use server blocks (@{}) instead of @() - the latter is used for Response.Write type of actions (like outputting a string from the server for example, where you don't need to run code).
