String m_XmlDocument = "http://localhost/bug/file.xml";
XmlTextReader reader = new XmlTextReader (m_XmlDocument);
reader.Read();

you receive the following System.ArgumentOutOfRangeException error message:

System.ArgumentOutOfRangeException: Specified argument was out of the range of valid values.

CAUSE

This exception was a regression from an earlier fix to the XMLDownloadManager class. The problem is caused by the limitation on connections to http://localhost. The default connection limit for http://localhost has changed from 2 to Int32.MaxValue (2,147,483,647). When the XmlDownloadManager class increments the value, the exception occurs.
