XML deserialization not working - there is an error in XML document (0, 0)

Question

I'm trying to deserialize an XML response but I can't seem to understand what is not working here

These are my classes (generated with the .NET developer tools)

[Serializable]
[XmlType(AnonymousType = true, Namespace = "http://www.crs.lombardia.it/schemas/DCSanita/GSSC/2007-01/calcolaIup/")]
[XmlRoot("GSSC.calcolaIupResponse", Namespace = "http://www.crs.lombardia.it/schemas/DCSanita/GSSC/2007-01/calcolaIup/", IsNullable = false)]
public partial class GSSCcalcolaIupResponse
{
    private param1 paramField;

    /// <remarks/>
    [XmlElementAttribute(Namespace = "")]
    public param1 param
    {
        get
        {
            return this.paramField;
        }
        set
        {
            this.paramField = value;
        }
    }
}

/// <remarks/>
[XmlType(AnonymousType = true)]
public partial class param1
{
    private string iupField;

    /// <remarks/>
    public string iup
    {
        get
        {
            return this.iupField;
        }
        set
        {
            this.iupField = value;
        }
    }
}

The xml response is like this:

<m:GSSC.calcolaIupResponse xmlns:m="http://www.crs.lombardia.it/schemas/DCSanita/GSSC/2013-01/calcolaIup/">
    <param>
        <iup>0000W05RNF</iup>
    </param>
</m:GSSC.calcolaIupResponse>

And here's the code for deserialization.

GSSCcalcolaIupResponse iup = new GSSCcalcolaIupResponse();
XmlSerializer serializer = new XmlSerializer(typeof(GSSCcalcolaIupResponse));

IUPDummyResponse retValue = new IUPDummyResponse();

using (TextReader reader = new StringReader(xml))
{
    if (soapFault == null)
        iup = (GSSCcalcolaIupResponse)serializer.Deserialize(reader);
}

The namespace in your class GSSCcalcolaIupResponse and namespace in your xml string are different. It is the reason. Just change to use the same namespace, it will fix the error:

- http://www.crs.lombardia.it/schemas/DCSanita/GSSC/2007-01/calcolaIup/
- http://www.crs.lombardia.it/schemas/DCSanita/GSSC/2013-01/calcolaIup/
