MVC：cshtml intellisense中缺少模型

Question

我正在.net中做一些示例MVC项目。出于某种原因，我的visual studio intellisense中缺少Model。我不知道我在这里错过了什么。请帮我看看原因。

控制器：

public class EmployeeController : Controller
{
    PersonalDetails personalDetails;

    public EmployeeController()
    {
        personalDetails = new PersonalDetails();
    }

    public ActionResult Employee()
    {
        return View("Employee", personalDetails.Employee(1));
    }
}

型号：

public class Employee
{
    public int ID { get; set; }
    public Nullable<int> EmployeeID { get; set; }
    public string FirstName { get; set; }
    public string LastName { get; set; }
}

查看：

@model EmployeeModel.Employee 

@{
    ViewBag.Title = "Employee";
}

<select id="name">
@foreach (var item in Model.ID)//Model is not coming here.
{
    <option value="value">@item</option>
}
