In ASP.Net MVC Core they removed BundleConfig.cs and replaced with bundleconfig.json file. you need to specify your bundle and minification logic in bundleconfig.json. If you don't have this file in your project add json file with this name.

bundleconfig.json

Content of this file should like below.

  // Configure bundling and minification for the project.
// More info at https://go.microsoft.com/fwlink/?LinkId=808241
[
  {
    "outputFileName": "wwwroot/css/site.min.css",
    // An array of relative input file paths. Globbing patterns supported
    "inputFiles": [
      "wwwroot/css/site.css"
    ]
  },
  {
    "outputFileName": "wwwroot/js/bundles.min.js",
    "inputFiles": [
      "wwwroot/js/site.js",
      "wwwroot/lib/jquery/dist/jquery.js",
      "wwwroot/lib/jquery/dist/jqueryvalidate.js"
    ],
    // Optionally specify minification options
    "minify": {
      "enabled": true,
      "renameLocals": true
    },
    // Optionally generate .map file
    "sourceMap": false
  }
