Description of Problem:


Steps to reproduce the problem:
1. Create an XmlTextReader (specifically without XmlReaderSettings)
var reader = new XmlTextReader(new MemoryStream(responseInBytes))

2. Load that reader into an XDocument
var doc = XDocument.Load(reader)


Actual Results:
Null reference exception


Expected Results:
Document should be loaded

How often does this happen? 
Every time

Additional Information:
This code works on ms.net.
The problem is in the XDocument.Load method (line 125).
It should check to see if the Settings property on the reader is null. If it is
it should use default values, something like:

125: XmlReaderSettings s = reader.Settings == null ? new XmlReaderSettings() :
reader.Settings.Clone();
