title: Design View not working on Visual Studio 2019 in ASP.NET Framework
body: <p>I started a new project with ASP.NET layout.</p>
  <p>The code is ok, but when I try to see the designer view, VS freezes and doesn't show it.</p>
  <p>I've tried repair, reinstall, <code>devenv.exe /SkipPkgs</code>... but still nothing...</p>
  <p>Sometimes when I type <kbd>Shift + F7</kbd>, I get an error &quot;class not registered&quot;, but not every time.</p>
  <p>Does someone have the same issue?</p>
