XElement root = new XElement("Root",
    new XElement(aw + "ChildInNamespace", "content"),
    new XElement("ChildInNoNamespace", "content")
);

if (root.Name.Namespace == XNamespace.None)
    Console.WriteLine("Root element is in no namespace");
else
    Console.WriteLine("Root element is in a namespace");

if (root.Element(aw + "ChildInNamespace").Name.Namespace == XNamespace.None)
    Console.WriteLine("ChildInNamespace element is in no namespace");
else
    Console.WriteLine("ChildInNamespace element is in a namespace");

if (root.Element("ChildInNoNamespace").Name.Namespace == XNamespace.None)
    Console.WriteLine("ChildInNoNamespace element is in no namespace");
else
    Console.WriteLine("ChildInNoNamespace element is in a namespace");

This example produces the following output:

Root element is in no namespace
ChildInNamespace element is in a namespace
ChildInNoNamespace element is in no namespace
