Radio buttons with separate labels for listing using MVC6 tag helpers

Question

My model contains an enumeration that I am trying to associate with a list of radio buttons so that only one value can be selected when submitting the form.

public enum Options
{
    [Display(Name="Option A")
    OptionA,
    [Display(Name="Option B")
    OptionB
}

public class MyModel
{
     public Options SelectedOption {get; set;}
     public string TextA{get; set;}
     public string TextB{get; set;}
}

In MVC 5, I would provide a switch input for each enumeration value, and the user could only select one. Thus, the code in the view for each switch is likely to look like this:

@Html.RadioButtonFor(m => m.SelectedOption, Options.OptionA)

The problem with MVC6 is that the helper input tag does not support the enum property out of the box. Therefore, if I try to add <input asp-for="SelectedOption"/>, all I get is a text box.

<div>
    <div>
        <input id="OptionA" type="radio" name="SelectedOption"/>
        <label for="OptionA">Option A</label>

    <div>
        <label for="TextA">Text A</label>
        <input type="text" id="TextA" name="TextA">
    </div>
<div>

<div>
<div>
    <input id="OptionB" type="radio" name="SelectedOption"/>
    <label for="OptionB">Option B</label>
</div>

    <div>
        <label for="TextB">Text A</label>
        <input type="text" id="TextB" name="TextB">
    </div>
