                    </label>
                </div>

                <div class="form-group">
                    @Html.LabelFor(m=>m.Customer.MembershipTypeId)
                   @*List of items*@
                    @Html.DropDownListFor(m=>m.Customer.MembershipTypeId, new SelectList(Model.MembershipTypes,"Id","Name"),"Select",new { @class="form-control"})
                </div>

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

Below is the Create action method from controller

 [HttpPost]
    public ActionResult Create(Customer customer)
    {
        return View();
    }

Answer 1

try to add an attribute route

[Route("~/customer/create")]
public ActionResult Create(Customer customer)

and add a model to the top of the view

@model Customer

@using (Html.BeginForm("Create", "Customer", FormMethod.Post)) {

and if you are using Net 4.8 or older you have to config attribute routing

public static void RegisterRoutes(RouteCollection routes)
{
    routes.IgnoreRoute(“{resource}.axd/{*pathInfo}”);
 
    routes.MapMvcAttributeRoutes();
 
    routes.MapRoute(
        name: “Default”,
        url: “{controller}/{action}/{id}”,
        defaults: new { controller = “Home”, action = “Index”, id = UrlParameter.Optional }
    );
}
