"The model item passed into the dictionary is of type 'System.Data.Entity.DynamicProxies But ..." MVC issue

Question

Ive really searched all over the web and im just stack on this problem.. pls help :( (new with MVC) when im trying to run a specific page , im getting the message:

System.InvalidOperationException: The model item passed into the dictionary is of type 'System.Data.Entity.DynamicProxies.Category_B85D1A3F838C0192719C683B1095328267C570F7A660F0D', but this dictionary requires a model item of type 'Leeoriyas.Models.Category'.

my controller "storecontroller" (the relevent part)

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

    namespace Leeoriyas.Controllers

public class StoreController : Controller
    {
        LeeoriyasFPEntities storeDB = new LeeoriyasFPEntities();
        // GET: Store


     public ActionResult Index()
            {
                return View(storeDB.Category.ToList());
            }
 public ActionResult Browse(string Category)
        {
            var categoryModel = storeDB.Category.Include("ArtS").Single(c => c.Name == Category);
                return View(categoryModel);
        }

my view (browse)

@model Leeoriyas.Models.Category


@{
    ViewBag.Title = "Browse";
}

<h2>Browsing category: @Model.Name</h2>

<ul>
    @foreach (var product in Model.ArtS)
    {
        <li>
            @product.Title
        </li>
    }
</ul>

You are send the parameter Category for page ex: http://yourdomain/Store/Browser/{category}? — Junior Porfirio, Jan 19 '17 at 17:55

You are not sending what is expected to your view. You specify a type of Leeoriyas.Models.Category, so ensure that you are passing an object of that kind. You should pass something like this:

 public ActionResult Browse(string category)
        {
            Leeoriyas.Models.Category categoryModel = storeDB.Category.Include("ArtS").Single(c => c.Name == category);
                return View(categoryModel);
        }

Ensure that the return of this line storeDB.Category.Include("ArtS").Single(c => c.Name == category); is of type Category

it says that it cant convert type of leeoriyas.category to Leeoriyas.Models.Category :( – Leeoriya Sapir Jan 19 '17 at 18:00
you have to write your object translator to convert your db entity to dto type – K D Jan 19 '17 at 18:03
It says that your view is expecting Leeoriyas.Models.Category but getting System.Data.Entity.DynamicProxies.Category_B85D1A3F838C0192719C683B1095328267C570F7A660F0D instead. You have to fix that. – NicoRiff Jan 19 '17 at 18:07
yeah but how should i do that ? – Leeoriya Sapir Jan 19 '17 at 19:58
be sure to return a object of the type Categoty, or else you can remove the strong type of your view (@model Leeoriyas.Models.Category) and return a var like you are doing. – NicoRiff Jan 19 '17 at 20:01
i removed it and it gives me a comiplation error – Leeoriya Sapir Jan 19 '17 at 20:33
