title: Returning plain text or other arbitary file in ASP.net
body: <p>If I were to respond to an http request with a plain text in PHP, I would do something like:</p>
  
  <pre><code>&lt;?php 
      header('Content-Type: text/plain');
      echo "This is plain text";
  ?&gt;
  </code></pre>
  
  <p>How would I do the equivalent in ASP.NET?</p>
