title: Calling TagHelpers from another TagHelper?
body: <p>Is there any way to get a TagHelper to render another TagHelper?</p>
  
  <p>Example TagHelpers;</p>
  
  <pre><code>public class OuterTagHelper : TagHelper
  {
      public override void Process(TagHelperContext context, TagHelperOutput output)
      {
          output.TagName = "";
          output.Content.SetContent("Hello &lt;inner&gt;&lt;/inner&gt;");
      }
  }
  
  public class InnerTagHelper : TagHelper
  {
      public override void Process(TagHelperContext context, TagHelperOutput output)
      {
          output.TagName = "";
          output.Content.SetContent("World!");
      }
  }
  </code></pre>
  
  <p>Example View;</p>
  
  <pre><code>&lt;outer&gt;&lt;/outer&gt;
  </code></pre>
  
  <p>Expected Result;</p>
  
  <pre><code>Hello World!
  </code></pre>
  
  <p>I know I probably should use a ViewComponent instead, but is it at all possible to achieve the expected behavior presented above?</p>
