Asp.net MVC -- System.Collections.Generic.List ERROR

Below worked until I changed it to access my "ViewModel" instead of the regular "Model".

Does anyone know how I can fix ?
-------------------------------------------------------------------------------------------------------------------------------
The model item passed into the dictionary is of type 'System.Collections.Generic.List`1[MWR.Models.MAINT_WORK_REQ]', but this dictionary requires a model item of type 'System.Collections.Generic.List`1[MWR.Areas.__Testing.ViewModel.MainPageModel]'.

Areas/__Testing/ViewModel/MainPageModel.cs

namespace MWR.Areas.__Testing.ViewModel
{
public class MainPageModel
{
public MAINT_WORK_REQ MR {get; set;}
public MAINT_WORK_REQ_COMMENTS MRC { get; set; }
}
}

-------------------------------------------------------------------------------------------------------------------------------
Index.cshtml

@model ListIEnumerable<MWR.Areas.__Testing.ViewModel.MainPageModel>

@foreach (var item in Model)
{
@Html.DisplayFor(modelItem => item.MR.ID)
@Html.DisplayFor(modelItem => item.MRC.ID_MWR)

@Html.DisplayFor(modelItem => item.MRC.ID)
}

public class MAINT_WORK_REQ2Controller : Controller

private MVC_testEntities db = new MVC_testEntities();

public ActionResult Index()
{
return View(db.MAINT_WORK_REQ.ToList()); ¿-------------- change to MainPageModel so this LIST matches “index.cshtml” LIST ?
}

What is ListIEnumerable in "@model ListIEnumerable<MWR.Areas.__Testing.ViewModel.MainPageModel>"?

It is really just the below, but still fails with the same error.

@model List<MWR.Areas.__Testing.ViewModel.MainPageModel>

Below are the updates, but it still fails.

Test #1, works = comment out Index.cshtml @foreach
Test #2, fails = run with Index.cshtml @foreach statement

Does anyone know how I can fix ?

The Index.cshtml @foreach statement gives an "Object reference not set to an instance of an object." ERROR.
