title: Publishing a website is not updating my CSS bundles
body: <p>When I run my code from Visual Studio in release mode, and check the bundled style sheet, I can see my updates to the css files in that bundle. However when I publish the website to the server or my local machine, my changes in the style sheets have not come through. The bundled style sheet is still the old one.</p>
  
  <p>I have tried an IIS reset, a clean build/rebuild, deleted all files from the IIS folder and re-published.</p>
  
  <p>I am using LESS if that makes any difference.</p>
  
  <p>My bundle config:</p>
  
  <pre><code>bundles.Add(new StyleBundle("~/bundles/requiredStyles").Include(
      "~/Content/Style/Libs/bootstrap.min.css",
      "~/Content/Style/Libs/font-awesome.min.css",
      "~/Content/Style/Globals/application.css",
      "/Content/Style/Libs/muliDropdown.css",
      "~/Content/Style/Libs/smoothDivScroll.min.css",
      "~/Content/Style/Libs/jasny-bootstrap.min.css"
  ));
  </code></pre>
  
  <p>I'm checking the bundled css by visiting <a href="http://www.mywebsite.com/bundles/requiredStyles" rel="noreferrer">http://www.mywebsite.com/bundles/requiredStyles</a></p>
  
  <p>So I made a change in application.css which is fine if I hit play in visual studio (in release mode), but when I publish to my local IIS, my change is no longer there.</p>
