xmldocument load error

[cheers00]

I am using nuget pacakge System.Xml.XmlDocument 4.0.0-beta-22819 and when I tried to load xml, I am getting the error System.Xml.XmlException: Root element is missing. for every valid xml file.

Code

            TextReader textReader = File.OpenText(@"xml\document.xml");
            XmlReaderSettings settings = new XmlReaderSettings();
            settings.IgnoreWhitespace = true;
            settings.DtdProcessing = DtdProcessing.Ignore;
            XmlDocument doc = new XmlDocument();
            // doc.LoadXml(textReader.ReadToEnd());

            using (StringReader sr = new StringReader(textReader.ReadToEnd()))
            using (XmlReader reader = XmlReader.Create(sr, settings))
            {
                doc.Load(reader);
            }

Is there a way to create a command line project and reference corefx component (here System.Xml.XmlDocument) from my local system and debug myself?

1.0.0-beta6-12005/CoreCLR, the latest version of coreclr has fixed XmlDocument.Load problem.

Confirmed it doesn't repro.
