MVC: a dictionary requires a model element of type "System.Collections.Generic.IEnumerable`1

I get this error and I'm not sure if I can do this, here is my code.

Application controller

public ActionResult AppView()
{
    List<Application> apps;
    using (ISiteDbContext context = _resolver.GetService<ISiteDbContext>())
    {
        apps = context.Applications.ToList();
    } 
    return PartialView("AppView", apps.OrderBy(a => a.Name).ToList());
}

Partially rendering is an element that resides in the home controller.

@{Html.RenderPartial("~/Views/Application/AppView.cshtml", new Example.Services.DAL.Application());}

and presentation of my application

@model IEnumerable<Example.Services.DAL.Application>

@{
    ViewBag.Title = "Applications";
}

<h2>Applications</h2>

<p>
    @Html.ActionLink("Add New Application", "Create")
</p>
<table>
    <tr>
        <th>
            @Html.DisplayNameFor(model => model.Name)
        </th>
        <th></th>
    </tr>

    @foreach (var item in Model)
    {
    <tr>
        <td>
            @Html.DisplayFor(modelItem => item.Name)
        </td>
        <td>
            @Html.ActionLink("Edit", "Edit", new { id = item.ID }) |
            @Html.ActionLink("Details", "Details", new { id = item.ID }) |
            @Html.ActionLink("Delete", "Delete", new { id = item.ID })
        </td>
    </tr>
    }

</table>

full error message:

The model element passed to the dictionary is of type 'Example.Services.DAL.Application', but this model requires the model type 'System.Collections.Generic.IEnumerable`1 [Example.Services.DAL.Application]'.

The error indicates that you are passing the wrong type. Change

@{Html.RenderPartial("~/Views/Application/AppView.cshtml", new Example.Services.DAL.Application());}

at

@{Html.RenderPartial("~/Views/Application/AppView.cshtml", new List<Example.Services.DAL.Application> { new Example.Services.DAL.Application() });}

AppView.cshtml @model IEnumerable<Example.Services.DAL.Application>, @{Html.RenderPartial("~/Views/Application/AppView.cshtml", new Example.Services.DAL.Application());}

. list Example.Services.DAL.Application()

@{Html.RenderPartial("~/Views/Application/AppView.cshtml", new Example.Services.DAL.Application());}


@{Html.RenderPartial("~/Views/Application/AppView.cshtml", new List<Example.Services.DAL.Application> { new Example.Services.DAL.Application() });}
