You can follow the steps below to set up Bootstrap 5 SASS using ASPNET Core.

1. Delete the /wwwroot/lib/bootstrap folder:
   • If your application already contains Bootstrap, you will need to delete these files.
2. Choose the scss folder and click install:
   • You can right-click wwwroot and select Add->Client-Side Library. Select unpkg provider, "[email protected]" library.
   • [1
3. You can create a file called bootstrap.custom.scss for testing.
   • You can right-click the bootstrap.custom.scss file and select Web Compiler->Compile file.
     • If you cannot find the Web Compiler option, you need to click this link to install the Web Compiler tool, and then restart VS.
   • bootstrap.custom.scss

     • $primary: #00ffff;
       $white:white;
       @import "../lib/bootstrap/scss/bootstrap";
       nav.navbar {
           background: linear-gradient($primary, $white)
       }
       

   • Modify the _Layout view

     • ... ...
       @*<link rel="stylesheet" href="~/lib/bootstrap/dist/css/bootstrap.min.css" />*@
       <link href="~/css/bootstrap.custom.css" rel="stylesheet" />
       ... ...
       @*<script src="~/lib/bootstrap/dist/js/bootstrap.bundle.min.js"></script>*@
       ... ...
