title: ASP.NET Core 2.1 - Scaffold Identity - CSS/Layout now ignored
body: <p>I have done the suggested scaffold operation to create the Identity source folders in my MVC 2.1 application. Prior the Bootstrap 4 CSS was working fine. Now, after the scaffold, it seems to be ignoring it and I can't figure out why.</p>
  
  <p>Has anyone else run into this issue?</p>
