Error when Deserializing XML into c# class derived from xsd.exe with namespace

Question

I will start off with I have read all of the other answers to this question and all of them (albeit good solutions) did not work in my case

I created a c# class from my xsd file with

xsd.exe /c neworder.xsd

It generated a class of 7000+ lines so I'll post relevant parts of it.

using System.Diagnostics;
using System.Xml.Serialization;
using System.Collections;

                serializer = new System.Xml.Serialization.XmlSerializer(typeof(neworder));
            }
            return serializer;
        }
    }
public static neworder Deserialize(string xml)
        {
            System.IO.StringReader stringReader = null;
            try

            finally
            {
                if ((stringReader != null))
                {
                    stringReader.Dispose();
                }
            }
        }

That is just a small snippet, the rest isn't that important right now as I feel like if this gets solved, I can solve the rest.

This is the beginning part of the XML file

</new-order>

I try to deserialize it with the following

    XmlSerializer ser = new XmlSerializer(typeof(neworder));
    neworder feed = (neworder)ser.Deserialize(new FileStream(filePath, FileMode.Open)) ;

The error that I get is the infamous:

There is an error in XML document (1, 2). http://www.foo.com/schema/w/v1.0'> was not expected.

I've read over and over again about making sure the root note as attribute XMLROOT which the above does. And it has the right namespace.

I've tried changing XmlRootAttribute to XmlRoot. Nothing. I've tried removing the namespace and re-doing the class and nothing.

Wrecking my brain on what could be wrong here because everything seems legit.

I am reading your XML in to a string from a file in the application build folder called xml.xml... you will need to get the XML string from somewhere else or create the xml.xml file and save your XML for the code above to work
