Re: How to tell the XmlSerializer to ignore all namespaces

can I see an example of the OutputObject?

Let's suppose it is really simple, like the following:
<Output>
   <element1>value1</element1>
   <element2 name="something"/>
   <element3>
         <subelt>foo</subelt>
   </element3>
</Output>

If I run this through xsd.exe, I can infer an XSD from it. Then if I run
xsd.exe /c on that XSD, I can generate a class that the XmlSerializer will
produce on de-serialization of the example XML document.   The generated
Output class is annotated with
[System.Xml.Serialization.XmlRootAttribute(Namespace="", IsNullable=false)]

How are you defining OutputObject and how is the mapping between the output
xml document and the OutputObject class defined?

You are so far correct in the way you described it.
Now I had to modified the classes to add namepaces to it.

now the Output class is annotated with
[System.Xml.Serialization.XmlRootAttribute(Namespace="mymessagenamespace",
IsNullable=false)]

but the xml document still wil not have the namespaces

I don't understand why you are adding namespaces to the class if the actual
document will not have namespaces.

Maybe you can look into the attribute overrides that are possible in XML
Serialization - perhaps that will do what you want.
