One of the Java webservices that I consume within my c# application has a returned type "marketCalendar" defined like following in the wsdl. WSDL's Target name space is http://www.xyz.com

}Problem# my c# application invokes a method GetMarketCalendar on the java webservice and does see the XML response coming in but can't deserialize it back into a marketCalendar response. So I started digging by using XGen generated class.
I noticed that for types country, exchange, calendarDay - c#'s default deserializer is comparing the namespace coming in the soap response to an empty string i.e.
if (((object) Reader.LocalName == (object)id84_country && (object) Reader.NamespaceURI == (object)id2_Item)) {
where incoming is Reader.NamespaceURI = "http://www.xyz.com" and id2_Item = Reader.NameTable.Add(@""); i.e. empty.
Is this a C# XMLSerializer bug or there is something wrong with the marketCalendar definition in wsdl?
