  • In general, you should post the [relevant code](http://stackoverflow.com/help/mcve). However, I believe this is a duplicate of http://stackoverflow.com/questions/4660142/what-is-a-nullreferenceexception-and-how-do-i-fix-it. – Adi Inbar Mar 29 '14 at 05:39

Try this:

You should add your website as an application under the default website or you set in the IIS to start from your website.
