XDocument Root.Elements() returning null

I'm trying to parse an xml file generated by running unit tests, but the xml.Root.Elements() is coming up as null.

Here a sample of the xml:

<?xml version="1.0" encoding="UTF-8"?>
<TestRun id="2ece436d-907d-4f59-9c81-0544b2f4f7cd" name="redacted" runUser="redacted" xmlns="http://microsoft.com/schemas/VisualStudio/TeamTest/2010">
  <TestSettings name="Default Test Settings" id="e00bb4af-1518-4b40-9905-19fa7b190f68">
    ... 
  </TestSettings>
  <Times creation="2015-02-18T11:47:02.7188640-05:00" queuing="2015-02-18T11:47:03.1819103-05:00" start="2015-02-18T11:47:03.2819203-05:00" finish="2015-02-18T11:47:05.5571478-05:00" />
  <ResultSummary outcome="Failed">
    <Counters total="74" executed="74" passed="73" error="0" failed="1" timeout="0" aborted="0" inconclusive="0" passedButRunAborted="0" notRunnable="0" notExecuted="0" disconnected="0" warning="0" completed="0" inProgress="0" pending="0" />
  </ResultSummary>

I want to retreive the <ResultSummary>'s outcome, but all Element() and Elements() calls on xml.Root are returning null. 

var xml = XDocument.Load(resultFile);
var outcome = xml.Root
    .Element("TestRun")
    .Element("ResultSummary")
    .Attribute("outcome")
    .Value;

I tried adding the namespace like in this answer but I'm still getting the same results:

var xml = XDocument.Load(resultFile);
XNamespace ns = "http://microsoft.com/schemas/VisualStudio/TeamTest/2010";
var outcome = xml.Root
    .Element(ns + "TestRun")
    .Element("ResultSummary")
    .Attribute("outcome")
    .Value;

Also, I'm not sure if Root is supposed to return <TestRun> or not, I tried running xml.Root.Element("ResultSummary") and I still get null.

How can I read this xml file?

Other way to get the Namespace is like this XNamespace ns = xml.Root.GetDefaultNamespace();

First of all, XDocument.Root gets the root element of the XML Tree. And in your case it is TestRun.

And, for getting object from a local name and a namespace, you can use XName.Get(string, string) method:

So, change your code as:

string ns = "http://microsoft.com/schemas/VisualStudio/TeamTest/2010";
var outcome = xml.Root
            .Element(XName.Get("ResultSummary", ns))
            .Attribute("outcome")
            .Value;

The result is: Failed
