title: How can I upload a file in MVC 6 under vNext?
body: <p> 
  In MVC 5 I used to do this:</p>
  
  <pre class="lang-cs prettyprint-override"><code>var context = (HttpContextBase)Request.Properties["MS_HttpContext"];
  var file = (HttpPostedFileBase)context.Request.Files[0];
  </code></pre>
  
  <p>Now these are not available in MVC 6 under vNext. How can I get the file(s) from the request?</p>
