Asp.net Can't create view IEnumerable<string>

Question

I'm following a book about C# (Pro asp.net MVC 3 Framework) It is a little out dated but there's not much difference compared to the newer versions.

Ebook: Ebook version, google link. I have the paper version of the book, but the page numbering is the same. I got stuck at page 205, it asks me to create a view named 'Menu' and with the model class IEnumerable<string> I can't create that, when I enter that I cannot click on 'ADD'

According to the book:

According to my editor:

I'm new to C# but I'll paste some of my code to let you guys understand it better.

{
    public class NavController : Controller
    {
      private IProductRepository repository;
      public NavController(IProductRepository repo)
      {
        repository = repo;
      }

      public PartialViewResult Menu() //Krijg hier geen VIEW met: "IEnumerable<string>" als Modelclass.
      {
        IEnumerable<string> categories = repository.Products
                                 .Select(x => x.Category)
                                 .Distinct()
                                 .OrderBy(x => x);
        return PartialView(categories);
      }
    }
}

Hopefully it's just something silly I did wrong.

Tips&adjustments are welcome!

Best regards

You can simply create a view then specify the Model :

@model IEnumerable<string>
@foreach (var str in Model)
{
   <li>
      @Html.LabelFor(m => str, "My Label")
      @Html.TextBoxFor(m => str)
      @Html.ValidationMessageFor(m => str)
   </li>
}

So as Stephen mentioned there's no need to specify the modal that way.
