MVC problem, connecting to Database

So I am kinda stuck here.

I have a test project going on and for some reason I can't get mineself connected to the database file.

I treid the tutorials but I can't get mine brains to crack this one down again.

In the App_Data folder I got a file named stalaerdenhout.sdf which contains 1 Table with 1 column.

Now I am trying to show the price on the browser that is in mine table.

Anyone know what I must fill in?

Table:

Prices

Column:

Paard:

€320,-

The Model folder named "stalaerdenhout.cs":

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

namespace Stal_Aerdenhout.Models
{
   public class stalaerdenhout
   {
   }
}

Now the problem is that I'm getting a respond of that the namespace Stal_Aerdenhout.Models already contains a definition.

So how do I progress from here?
