title: Visual Studio 2013 does not update minified bootstrap.css
body: <p>In my ASP .NET MVC 5.1 application in <code>bootstrap.css</code> file in section: </p>
  
  <pre><code>@media (min-width: 768px) {
    .dl-horizontal dt {
      float: left;
      width: 160px;
      overflow: hidden;
      clear: left;
      text-align: right;
      text-overflow: ellipsis;
      white-space: nowrap;
    }
    .dl-horizontal dd {
      margin-left: 180px;
    }
  </code></pre>
  
  <p>I changed <code>width: 160px;</code> to <code>width: 260px;</code> and <code>margin-left: 180px;</code> to <code>margin-left: 280px;</code>.</p>
  
  <p>I saved, reloaded, later restarted Visual Studio. In my website in Chrome I checked loaded styles:</p>
  
  <pre><code>.dl-horizontal dt {
  float: left;
  width: 160px; //STILL 160px !
  overflow: hidden;
  clear: left;
  text-align: right;
  text-overflow: ellipsis;
  white-space: nowrap;
  }
  </code></pre>
  
  <p>so I checked <code>bootstrap.min.css</code> via Visual Studio and I saw that changes I've made to the <code>bootstrap.css</code> are were not applied to <code>bootstrap.min.css</code> so I applied them manually to minified file and Chrome loaded them correctly.</p>
  
  <p>How to make VS2013 update this minified file?</p>
  
  <hr>
  
  <p>EDIT: I must say that before VS2013(today) did update <code>boostrap.min.css</code> after making changes in <code>boostrap.css</code>. It just didn't do it after these changes.</p>
