The type arguments for method cannot be inferred from the usage on Model

Im gettting this error in my view on a LinQ Statement of my Model and i dont know why

This is my controller: 

namespace Arpon.Web.Brain.Pos.Models
{
    public class HomePosController : BaseController
    {
        public ActionResult Index(string txtInput)
        {
            return View("~/Views/HomePos/Index.cshtml",db.VENTA_PLATILLOS.ToList());
        }
     }
}

This is my Model

namespace Arpon.Web.Brain.Pos.Models
{
    public partial class VENTA_PLATILLOS
    {
        public System.DateTime Fecha { get; set; }
        public string Clave_PDV { get; set; }
        public int Cheque { get; set; }
        public int Linea { get; set; }
        public int Platillo { get; set; }
        public string Nombre_Platillo { get; set; }
        public string Tipo { get; set; }
        public int Cantidad { get; set; }
        public decimal Precio { get; set; }
        public decimal Total { get; set; }
        public int Turno { get; set; }
        public string Nombre_Turno { get; set; }
        public int Grupo { get; set; }
        public string Nombre_Grupo { get; set; }
        public string Nombre_Pdv { get; set; }
        public string Estatus_Pla { get; set; }
        public string Estatus_Che { get; set; }

    }
}

And my View::

@model ICollection<Arpon.Web.Brain.Pos.Models.VENTA_PLATILLOS>
<!--other code-->
<select>
    <option value="">Todos</option>
    @foreach (var item in   Model.Select(l => l.Nombre_Pdv).OrderByDescending(a=>a.Length).Distinct())
    {
        <option value="@item">@item</option>
    }
</select>

Im getting The folling error at the 'Model.' part "The type argument for method cannot be inferred from usage" What i am doing wrong?

UPDATED

I solved the Problem Changing my model declaration 'ICollection' to 'List' 

@model List<Arpon.Web.Brain.Pos.Models.VENTA_PLATILLOS>

The issue could be that your loop does not know what 'Type' it is iterating. Try using an explicit cast.

@foreach (var item in (List<string>) Model.Select(l => l.Pdv).OrderByDescending(a=>a.Length).Distinct())
