foreach statement cannot operate on variables of type 'Customers' because no a public instance definition for 'GetEnumerator'

I am trying to send a enumerable customer object in ViewResult to Index view of customers. but i am not able to use foreach with Model on the view page. The error associated with model says -

"foreach statement cannot operate on variables of type 'Customers' because 'Customers' does not contain a public instance definition for 'GetEnumerator'"

i tried to switch the code with an array but the problem remains

public class Customers
    {
        public int Id { get; set; }
        public string Name { get; set; }


    }

//Customer Controller
public class CustomersController : Controller
    {

        public IActionResult Index()
        {
            var customers = GetCustomers();
            return View(customers));
        }

        public IActionResult Details(int id)
        {
            var customer = GetCustomers().SingleOrDefault(c => c.Id == id);

            return View(customer);

        }

         private IEnumerable<Customers> GetCustomers()
         {
             var customer =  new List<Customers>
             {
                 new Customers { Id = 1, Name = "John Smith"},
                 new Customers { Id = 2, Name = "Mary Williams"}
             };

            return customer;
         }


    }

//View page Index

 @foreach (var customer in Model)
        {
            <tr>
                <td><a asp-area="" asp-controller="Customers" asp-action="Details">@customer.Name</a></td>
            </tr>
        }

The error displayed Under Model when the foreach statements executes, the it should output the name of the customers accordingly

In view you describe model as single object Customer.

Change your view:

@model IEnumerable<Vidly.Model.Customer>

Or:

@model List<Vidly.Model.Customer>
