title: Syntax Highlighting for .tt files?
body: <p>Is there any way to tell Visual Studio 2010 to enable syntax highlighting for .tt files? I do have a directive to set the extension:</p>
  
  <pre><code>&lt;#@ output extension=".ascx" #&gt;
  </code></pre>
  
  <p>So I'd like Visual Studio to treat the file as an ascx file for the purpose of Syntax Highlighting.</p>
