title: How to set file association to custom .env filename in VSCode settings?
body: <p>I have a <code>.envDEV</code> file name that I use for development environment variables.</p>
  
  <p>And VSCode is not recognizing it as a <code>dotenv</code> file.</p>

  <p>If I change the language mode for the file, it seems to work (the proper styles are applied, 'though the icon won't change). But it goes away whenever I close and re-open the file.</p>

  <p>I'm trying to set a custom file association for this, but without success so far.</p>
  
  <p><strong>seetings.json</strong></p>
  
  <pre><code>"files.associations": {
    "*.envDEV": "dotenv"      // DOES NOT WORK
    "*.envDEV": ".env"        // DOES NOT WORK
  },
  </code></pre>
  
  <p>Does anybody know how to do this?</p>
