title: @Html.LabelFor helper not inserting an asterisk for a required textarea
body: <p>I'm working on an ASP.Net MVC 5 project uisng razor views.</p>
  
  <p>I have multiple textarea fields in a form using html helpers.</p>
  
  <p>Everything seems to be working ok however the labels for textareas don't show the "*" to denote a required field like the other fields do. Is there a special reason for this? How do I get it to do that?</p>
  
  <p>My model looks like this (only relevant info shown):</p>
  
  <pre><code>    [Required, DisplayName("Agreed Action")]
      public string AgreedActionText { get; set; }
  </code></pre>
  
  <p>My View looks like this:</p>
  
  <pre><code>&lt;div class="form-group"&gt;
    @Html.LabelFor(model =&gt; model.AgreedActionText, new { @class = "col-xs-12 col-sm-2  col-md-2 control-label" })
    &lt;div class="col-xs-12 col-sm-10 col-md-10"&gt;
      @Html.TextAreaFor(model =&gt; model.AgreedActionText, new { @class = "form-control" })
      @Html.ValidationMessageFor(model =&gt; model.AgreedActionText)
    &lt;/div&gt;
  &lt;/div&gt;    
  </code></pre>
  
  <p>Working example:</p>
  
  <p>Model:</p>
  
  <pre><code>[Required, DisplayName("Action Title")]        
  public string ActionShort { get; set; }
  </code></pre>
  
  <p>View:</p>
  
  <pre><code>&lt;div class="form-group"&gt;
    @Html.LabelFor(m =&gt; m.ActionShort, new { @class = "col-xs-12 col-sm-4 col-md-4 control-label" })
    &lt;div class="col-xs-12 col-sm-8 col-md-8"&gt;
      @Html.TextBoxFor(m =&gt; m.ActionShort, new { @class = "form-control" })
      @Html.ValidationMessageFor(m =&gt; m.ActionShort)
    &lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>This works:</p>
  
  <pre><code>&lt;label class="col-xs-12 col-sm-2 col-md-2 control-label" for="AgreedActionText"&gt;Agreed   Action Text&lt;span style="color:red"&gt; *&lt;/span&gt;&lt;/label&gt;
  </code></pre>
  
  <p>But it's not really the solution I was after, I want the helper to automatically know it's a required field and add the asterix like it does with text boxes and other input fields.</p>
