Having a problem deserializing types returned by Yahoo geocoding service

Question

I am working with the Yahoo geocoding service, a RESTful XML-based service. I cannot get the XML response fully deserialized.

I've created two classes for the result: PlaceFinderResultSet and Result. PlaceFinderResultSet correctly deserializes the simple types, but I cannot get the complext "Result" node to be deserialized - my Result property is null.

[XmlRoot(ElementName="ResultSet")]
public class PlaceFinderResultSet
{

    [XmlElement("Error")]
    public int Error { get; set; }

    [XmlElement("ErrorMessage")]
    public string ErrorMessage { get; set; }

    [XmlElement("Locale")]
    public string Locale { get; set; }

    [XmlElement("Quality")]
    public int Quality { get; set; }

    [XmlElement("Found")]
    public bool Found {get;set;}

    [XmlElement("Result",Type=typeof(Result),DataType="Result")]
    Result Result { get; set; }
}

[XmlRoot(ElementName = "")]
[XmlType(Namespace = "http://www.tempuri.com", TypeName = "Result")]
public class Result
{
    [XmlElement("quality")]
    public int Quality{get;set;}

    [XmlElement("latitude")]
    public double Latitude{get;set;}

    /** the rest of the code was omitted for brevity **/
 }

Here is an example of the XML I am trying to deserialize:

<?xml version="1.0" encoding="UTF-8"?>
<ResultSet version="1.0">
    <Error>0</Error>
    <ErrorMessage>No error</ErrorMessage>
    <Locale>us_US</Locale>
    <Quality>99</Quality>
    <Found>1</Found>
    <Result>
        <quality>72</quality>
        <latitude>50.000000</latitude>
        <longitude>-77.000000</longitude>
        <offsetlat>50.000000</offsetlat>
        <offsetlon>-77.000000</offsetlon>
        <radius>500</radius>
        <name>50 -77</name>
        <line1>Route de la Baie-James</line1>
        <line2>Baie-James, QC  J0Y</line2>
        <line3></line3>
        <line4>Canada</line4>
        <house></house>
        <street>Route de la Baie-James</street>
        <xstreet></xstreet>
        <unittype></unittype>
        <unit></unit>
        <postal>J0Y</postal>
        <neighborhood></neighborhood>
        <city>Baie-James</city>
        <county>Baie-James</county>
        <state>Quebec</state>
        <country>Canada</country>
        <countrycode>CA</countrycode>
        <statecode>QC</statecode>
        <countycode></countycode>
        <hash></hash>
        <woeid>12697261</woeid>
        <woetype>11</woetype>
        <uzip>J0Y</uzip>
    </Result>
</ResultSet>

Ok I had a go, and I got it working by...

Commenting out the [XmlType] Attribute completely, and.... change this line:

Result Result { get; set; }

to this:

public Result Result { get; set; }

Gah that serializer is picky!
