title: How can I get region collapsing/expanding with #region / #endregion for TypeScript in Visual Studio CE 2019?
body: <p>We have been using "region collapsing" in TypeScript for some time now, like so:</p>
  
  <pre><code>//#region GUI handlers
  ...some code related to handling GUI events...
  //#endregion
  </code></pre>
  
  <p>and this has been working fine in VS2015 CE and VS2017 CE (a little "-" or "+" appears in the left gutter of the code window, which you can use to collapse/expand the block of code, as in C#).</p>
  
  <p>I recently switched to VS2019 CE and this functionality is no longer working.
  I've tried installing the "Web Essentials 2019" extension, but that didn't help. I also have the "Editor Enhancements" extension installed right now, but that doesn't work either...</p>
  
  <p>Does someone know how to enable this in VS2019 CE?
  Thanks!</p>
