title: Unable to enable VS 2019 Live Visual Tree. No option for "Enable UI Debugging Tools"
body: <p>I wanted to use the Visual Studio 2019 (version 16.8.3) &quot;Live Visual Tree today&quot; in my WPF application.   So I went into Tools &gt;&gt; Options &gt;&gt; Debug &gt;&gt; General and was surprised to discover that there was no checkbox for &quot;Enable UI Debugging Tools&quot; or anything like that.  I know it used to be there.  Now it's not.</p>
  <p>I went through all the other Debug options and could see no similar option anywhere.</p>
  <p>And when I debug now, although I can bring up the &quot;Live Visual Tree&quot; window, it tells me that &quot;UI Debugging is either disabled, not supported by the current application, or the application execution is paused&quot;.</p>
  <p>I do this when it is <em>not</em> paused, if that matters.  My app is .NET 5.0 using WPF in C#.</p>
  <p>So what happened to the Live Visual Tree?</p>
