The formatter threw an exception while trying to deserialize the message: There was an error while trying to deserialize parameter http://tempuri.org/:queryBuilderArgs. The InnerException message was ‘Element ‘http://tempuri.org/:queryBuilderArgs’ contains data from a type that maps to the name ‘http://schemas.datacontract.org/2004/07/XppClasses:SRSQueryBuilderArgs’. The deserializer has no knowledge of any type that maps to this name. Consider using a DataContractResolver or add the type corresponding to ‘SRSQueryBuilderArgs’ to the list of known types – for example, by using the KnownTypeAttribute attribute or by adding it to the list of known types passed to DataContractSerializer.’.  Please see InnerException for more details.
