We are starting to use nhibernate and have setup a Session Manager to create a new SessionFactory. I need to modify some information the 1st time the app starts.

I open the config file (not app.config) using an XDocument. 

```
<settings>
  <hibernate-configuration xmlns="urn:nhibernate-configuration-2.2">
    <reflection-optimizer use="false"/>
    <session-factory>
       <property name="x">SomeValue</property>
    </session-factory>
  </hibernate-configuration>
</settings>

XDocument xdoc = XDocument.Load(<file>);
var x = xdoc.Root.Element("hibernate-configuration");

```

x is null unless i remove the xmlns. What am I missing?
