Answer 1

I had the same problem, the program that should read the XML could not handle the "utf" in lower case.

Found this simple workaround:

    XmlWriterSettings settings = new XmlWriterSettings();

    settings.Indent = true;
    settings.OmitXmlDeclaration = true;
    settings.NewLineHandling = NewLineHandling.Replace;
    settings.NewLineOnAttributes = true;       

                using (
                    XmlWriter xmlWriter =
                        XmlWriter.Create(
                            Application.StartupPath + @"\Output\products.xml", settings))
                {

                    xmlWriter.WriteStartDocument();
                    xmlWriter.WriteRaw("\r\n");
                    xmlWriter.WriteStartElement("products");

etc....
