c# - Omitting all xsi and xsd namespaces when serializing an object in .NET?

Question

The code looks like this:

StringBuilder builder = new StringBuilder();
XmlWriterSettings settings = new XmlWriterSettings();
settings.OmitXmlDeclaration = true;
using (XmlWriter xmlWriter = XmlWriter.Create(builder, settings))
{

    XmlSerializer s = new XmlSerializer(objectToSerialize.GetType());
    s.Serialize(xmlWriter, objectToSerialize);
}

The resulting serialized document includes namespaces, like so:

<message xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xmlns:xsd="http://www.w3.org/2001/XMLSchema" 
    xmlns="urn:something">
 ...
</message>

To remove the xsi and xsd namespaces, I can follow the answer from How to serialize an object to XML without getting xmlns=”…”?.

I want my message tag as <message> (without any namespace attributes). How can I do this?

...
XmlSerializer s = new XmlSerializer(objectToSerialize.GetType());
XmlSerializerNamespaces ns = new XmlSerializerNamespaces();
ns.Add("","");
s.Serialize(xmlWriter, objectToSerialize, ns);
