title: EventReceiver to Create folder sharepoint 2010
body: <p>I have this event receiver c# class that I am trying to implement on a Sharepoint site. It did not work. I have deployed it from visual studio 2010 after it was build ok. Does anyone see what is the problem? Is the code ok? or is the problem on the SP? Thank you.
   - here is the new code </p>
