gistfile1.cs

class CustomerController : Controller {
  public ActionResult List() {
    var customers = DB.GetAllCustomers();

    ViewModel.Customers = customers;
    ExtendViewModel<Customer>("Url", customer => Url.Action("details", new { customer.Id }));

    return View();
  }

  public ActionResult Details(int id) {
    // ...
  }
}

// Then in the view page, use the viewmodel like this:
// <ul>
// @foreach (var customer in View.Customers) {
//   <li><a href="@customer.Url">@customer.Name</a></li>
// }
// </ul>
