title: aspx page rendered as empty/blank
body: <p>i have deployed web application (asp.net webform) on IIS, but the index.apsx page shows as empty/blank in browser(Chrome/IE/Microsoft-Edge) and Mozila-firfox show as :</p>
  
  <pre><code>XML Parsing Error: no element found
  Location: http://localhost:90/index.aspx
  Line Number 1, Column 1:
  </code></pre>
  
  <p><strong>index.aspx</strong> is login page as well as start page.
  I have searched a lot but did not find solution that works for me.</p>
  
  <p><strong>NOTE:</strong> The html page shows fine after deployment. Also in VS-2012 the web application works fine.</p>
  
  <p>Any help regarding this ? Let me know if you need web.config file or any other file that help you understand the problem. thanks</p>
