DataType.MultilineText does not generate textarea #147

In MVC5 you could do this:

public class ApplicationUser : IdentityUser
{
    [DataType(DataType.MultilineText)]
    public string Bio { get; set; }
}

That would generate a textarea tag to make it multi-line. Not working in MVC6 (rc1). The generated input control is not multi line.

From @dougbu

As mentioned in the original MVC issue: The generated view uses <input asp-for="Bio" class="form-control" />. Scaffolding should instead generate a <textarea/> element or use the more-general @Html.EditorFor() HTML helper.

The workaround is to use

@Html.EditorFor(m => m.Bio, additionalViewData: new { htmlAttributes = new { @class = "form-control" }})

or

    <textarea asp-for="Bio" class="form-control"></textarea>

Hi see that the issue still persist on asp.net mvc core version 2.2

For a model such

public class Dto
{
    [DataType(DataType.MultilineText)]
    public string Name {get; set; }
}

The razor

            @Html.EditorFor(m => m.Name, additionalViewData: new { htmlAttributes = new { @class = "form-control" } })
            <input asp-for="Name" class="form-control" />

renders

<textarea class="form-control text-box multi-line" id="Name" name="Name"></textarea>
<input class="form-control" type="text" id="Name" name="Name" value="" />

Any update?
