asp.net mvc - The type name 'Models' does not exist in the type 'System.Web.Helpers.Chart'

I am getting error : The type name 'Models' does not exist in the type 'System.Web.Helpers.Chart'

Please help me in resolving this. Here is the code developed with mvc and razor syntax:

Model

  using System;
  using System.Collections.Generic;
  using System.Linq;
  using System.Web;
  using System.Web.Mvc;


  namespace Chart.Models
  {
            public class FooBarModel
            {
                public IEnumerable Locations { get; set; }
            }
  }

Controller:

        using Chart.Models;
        using System;
        using System.Collections.Generic;
        using System.Linq;
        using System.Web;
        using System.Web.Mvc;

        namespace Chart.Controllers
        {

            public class FooController : Controller
            {
                //
                // GET: /Foo/

                public ActionResult Index()
                {
                    var locations = new[]
                    {
                        new SelectListItem { Value = "US", Text = "United States" },

                        new SelectListItem { Value = "CA", Text = "Canada" },
                        new SelectListItem { Value = "MX", Text = "Mexico" },
                    };

                    var model = new FooBarModel
                    {
                        Locations = locations,
                    };

                    return View(model);

                }       
            }
        }

View Code:

        @model Chart.Models.FooBarModel             // intellisense shows error on this line as well


        @{
            Layout = null;
        }

        

        
        
            

            
            
        
        
            
        
            
        
        

Answer

You could fully qualify the namespace to avoid the collision with the System.Web.Helpers.Chart class which is in scope in the view:

@model global::Chart.Models.FooBarModel

Basically it's a bad idea to use class names in your namespaces. For example Chart is a class defined in the System.Web.Helpers namespace.

For example:

namespace MyCompany.MyApplication.Models
