The rendered HTML element of EditorFor helper in ASP.NET Core MVC includes the property name of parent model

[boyandim]

We do have the following model structure:

namespace AspNetCoreApp28.Models
{
    public class HomePageModel
    {   
        public OrderViewModel Order { get; set; }
    }

    public class OrderViewModel
    {
        public int OrderID
        {
            get;
            set;
        }
        public string ShipName
        {
            get;
            set;
        }
    }
}

In the HomeController we send an instance of the HomePageModel to the Index view.

In the Index view we use a partial view and send just the OrderViewModel using the Order property of the HomePageModel to partial view:

@{ ViewData["Title"] = "Home Page"; }

@model AspNetCoreApp28.Models.HomePageModel

The partial view contains one EditorFor helper for the string ShipName

@(Html.EditorFor(m => m.ShipName))

The result of rendering is an input element with a name attribute name="Order.ShipName" instead of just "ShipName".

In MVC5 the same setup will render an input element with name attribute "ShipName" without the Order, which in my case works fine with my MVVM logic. Is there any way in ASP.NET Core MVC to avoid rendering "Order" in the name attribute of the input element?

Thanks for contacting us, @boyandim. @dougbu, can you please look into this? Thanks!

This is surprising because MVC 5 has similar logic to ASP.NET Core around mapping Linq expressions to expression names. Do you have a sample showing MVC 5 behaving as you describe? If yes, I would appreciate a minimal repro project that illustrates the problem, preferably hosted in a GitHub repo.
