This error is due to the XmlSerializer encountering the unexpected KML header 
element (as it is expecting straight XML elements). I am trying to work out how 
to 
use XmlSerializer for serialising/deserialising XML and am having this problem.
Cheers,
Katie

The Serializer has been developed to Schema version 2.1 and google maps is now
outputting version 2.2 and the header of .... 2.2 is not recognised?

in kml.cs change the class declaration to look like this:

 [XmlRoot(ElementName = "kml", Namespace = "http://www.opengis.net/kml/2.2")]
    //--if you add the namespace, then all children get a blank namespace attrib...
    // [XmlRoot(ElementName = "kml")]
    public class KMLRoot
    {

That got me around this issue, the other option is to strip the attributes out 
of the 
KML file you are deserializing altogether before loading it. 

ie change

<kml xmlns="http://www.opengis.net/kml/2.2" 
xmlns:gx="http://www.google.com/kml/ext/2.2" 
xmlns:kml="http://www.opengis.net/kml/2.2" 
xmlns:atom="http://www.w3.org/2005/Atom">

to

<kml>

Add the namespace declaration to the xmlroot attribute as mentioned by 
deathpatrolband and also around ln 76 of XmlSerializer.cs change the namespace 
manager declaration like so:

   XmlSerializerNamespaces xmlns = new XmlSerializerNamespaces();
   xmlns.Add("", "http://www.opengis.net/kml/2.2");

That will ditch the xsi and xsd namespaces.

I am trying this but cannot seem to get any results from trying the 
suggestions, was wondering if this worked for everyone that tried it?
