xml deserialization properties null Walmart marketplace API

Question

I am having a problem with a XML deserialization from Walmart Items API.

This is code that i am using to deserialize the response. Does anyone have idea on how to deserialize the properties without namespace? I tried to set default namespace to http://walmart.com but that did not work.

This is the code.

var resp = await client.GetAsync(fullurl);
var serializer = new XmlSerializer(typeof(T));
string xmlstr = await resp.Content.ReadAsStringAsync();
using (TextReader reader = new StringReader(xmlstr))
{
    T itemResps = (T)serializer.Deserialize(reader);
}

The properties under ns:price (currenty , amount) have no namespace while all other elements have namespace.

This is a response from the walmart api server:

This is the Sample response from walmart item API. It does not contain namespace on all elements. I think it used to come like this. but it does not come anymore.
