finding element that defines namespace linq

have the folowing xml

<configuration>
<Settings version='1.0'>

    <applications>
 <conn:Connections xmlns:conn='urn:Connections/1.0'>
          <conn:data name='Auditing'>
            <conn:table>foo</conn:tableowner>
          </conn:data>
</conn:Connections >
<applications>
<configuration>

Can get an element without a namesapace via

 string name = "string name = "dbconnections";
    XElement dbconnections = config.Descendants( name).First();";

XElement dbconnections = config.Descendants( name).First();

but can't get the conn element with the following code:

name = "Connections";
XNamespace ns2 = "urn:Connections/1.0";
var dataArea = from x in config.Descendants(ns2 + name)
