DropDownList not passing values to my controller

Question

I have successfully populated my drop down list using a dropdownlistfor html helper, however when I submit the form the selected items value is not being passed with the model into the action result. Here is my code sample

Customer Model

public class Customer
{
    public int Id { get; set; }

    [Required]
    [StringLength(255)]
    public string Name { get; set; }

    [StringLength(11)]
    [Display(Name="Date of birth")]
    public string BirthDate { get; set; }

    public bool IsSubscribedToNewsLetter { get; set; }

    public MembershipType MembershipType { get; set; }

    [Display(Name = "Membership type")]
    public MembershipType MembershipTypeId { get; set; }
}

MembershipType Model

public class MembershipType
    {
        public int Id { get; set; }
        [StringLength(15)]
        public string Name { get; set; }
        public short SignUpFee { get; set; }
        public byte DurationInMonths { get; set; }
        public byte DiscountRate { get; set; }
    }

Customer View Model

   public class NewCustomerViewModel
    {
        public IEnumerable <MembershipType>MembershipTypes { get; set; }
        public Customer Customer { get; set; }
    }

View

@model MovieApp.ViewModels.NewCustomerViewModel
@{
    ViewBag.Title = "New";
    Layout = "~/Views/Shared/_Layout.cshtml";
}

<h2>New Customer</h2>
@using (Html.BeginForm("Create", "Customers"))

{
    <div class="form-group">
        @Html.LabelFor(c => c.Customer.Name)
        @Html.TextBoxFor(c => c.Customer.Name, new { @class = "form-control" })
    </div>
<div class="form-group">
    @Html.LabelFor(c => c.Customer.BirthDate)
    @Html.TextBoxFor(c => c.Customer.BirthDate, new { @class = "form-control" })
</div>

<div class="form-group">
    @Html.LabelFor(c => c.Customer.MembershipType)
    @Html.DropDownListFor(c => c.Customer.MembershipType
    ,new SelectList(Model.MembershipTypes, "Id","Name")
    ,"Select Membership Type"
    ,new { @class = "form-control" })
</div>


<div class="checkbox">
    <label>
        @Html.CheckBoxFor(c => c.Customer.IsSubscribedToNewsLetter) Subscribed to newsletter?
    </label>
</div>

<button type="submit" class="btn btn-primary">Save</button>
}

Action

public ActionResult New()
        {
            var  DBmebershipTypes= _context.MembershipTypes.ToList();
            var ViewModel = new NewCustomerViewModel()
            {
                MembershipTypes = DBmebershipTypes

            };
            return View(ViewModel);
        }

Post Action

 [HttpPost]
        public ActionResult Create(Customer customer)
        {
             _context.Customers.Add(customer);
             _context.SaveChanges();
             return RedirectToAction("Index", "Customers");
        }

When I debug the program, all inputed values are in memory, but the moment it has to be saved to database, dropdownlist selection doesent get saved.

Update your Customer Class you have wrong type for MembershipTypeId set it to int hopefully this'll work for you.

[Display(Name = "Membership type")]
public int MembershipTypeId { get; set; }
