Since there are still too many errors to fix, I rather rewrote the entire test
as:

-- 571650.cs --
using System;
using System.IO;
using System.Xml;
using System.Xml.Schema;

public class TEst
{
        public static void Main ()
        {
var schemas = new XmlSchemaSet();
var xsd = schemas.Add("", "571650.xsd");
var file = "571650.xml";
var settings = new
XmlReaderSettings{ValidationType=ValidationType.Schema,Schemas=schemas};
using(var reader = XmlReader.Create(File.OpenText(file),settings))
        while (!reader.EOF)
                reader.Read ();

        }
}

-- 571650.xsd --
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:element name="foo" />
</xs:schema>

-- 571650.xml --
<foo/>


For resolution, I fixed it in svn (r150187), while I believe this is rather a
NET bug which incorrectly treats "" as if it were null. We do allow null
TargetNamespace, which is to represent a schema without explicit
targetNamespace attribute, and XmlSchemaSet.Add(string, XmlReader) should
differentiate "" and null for the first parameter of this method.
