I am trying to install kendo UI for ASP.NET MVC application and I am getting following error. htmlhelper does not contain a definition for kendo

I have working ASP.NET project with kendo ui and I have copied require kendo styles and script in require folder, added namespace detail in web.config, add references in bundleConfig.cs and and kendo.mvc dll in reference. I have followed following tutorial 

<http://docs.telerik.com/kendo-ui/aspnet-mvc/asp-net-mvc-5>

I am not what I am missing, also both application are ASP.NET MVC 5.

test code is as following which I am trying to make it work

```
 @(Html.Kendo().DatePicker().Name("datepicker"))

```
