XML deserialisation problems

[Richard Lewis]

I have a web service that is used from a Pocket PC device using .NET CF
1.1

The webservice creates an object structure and serialises the object
structure to create the following SOAP response

<?xml version="1.0" encoding="utf-8" ?>
<soap:Envelop e xmlns:soap="htt p://schemas.xmlsoap .org/soap/envelope/"
xmlns:xsi="http ://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http ://www.w3.org/2001/XMLSchema">
<soap:Body>
<RegisterMobile DeviceResponse xmlns="http://mobile.project. net/">
<RegisterMobile DeviceResult>
<Status>Already Registered</Status>
<DataObject xsi:type="Proje ctSpecificDevic e" HostName="POCKE T PC"
ProcessorUID="0 8590050-XXXX-XXXX" IMEI="" />
<ServerDatetime >2006-08-29T14:25:13.657 8286+01:00</ServerDatetime>
</RegisterMobileD eviceResult>
</RegisterMobileD eviceResponse>
</soap:Body>
</soap:Envelope>

I have the following thinds setup in the device code (C#)


[System.Xml.Seri alization.XmlTy peAttribute(Nam espace="http://mobile.proj
ect.net/")]
public class ProjectSpecific Device: Device
{
}

public class Device
{
[XmlAttribute]
public string HostName;

[XmlAttribute]
public string ProcessorUID;

[XmlAttribute]
public string IMEI;
}

The webservice interface has the following attributes

[System.Diagnost ics.DebuggerSte pThroughAttribu te()]
[System.Componen tModel.Designer CategoryAttribu te("code")]
[System.Web.Serv ices.WebService BindingAttribut e(Name="Client
AdapterSoap", Namespace="http ://mobile.project. net/")]
[System.Xml.Seri alization.XmlIn cludeAttribute( typeof(ProjectS pecificDevi
ce))]
[System.Xml.Seri alization.XmlIn cludeAttribute( typeof(Registra tionRequest
))]
public class WebServiceInteg rator
{
/// <remarks/>

[System.Web.Serv ices.Protocols. SoapDocumentMet hodAttribute("h ttp://mobil
e.project.net/RegisterMobileD evice",
RequestNamespac e="http://mobile.project. net/",
ResponseNamespa ce="http://mobile.project. net/",
Use=System.Web. Services.Descri ption.SoapBindi ngUse.Literal,
ParameterStyle= System.Web.Serv ices.Protocols. SoapParameterSt yle.Wrapped)
]
public ResponsePack RegisterMobileD evice(RequestPa ck request)
{
object[] results = this.Invoke("Re gisterMobileDev ice", new object[] {
request});
return ((ResponsePack) (results[0]));
}
}


Up until recently this was processed correctly and the call to the
webservice succeeded but I now cannot get this call to succeed.

When calling the Webservice I get the following Exception thrown when
the above is processed on the device.

Cannot find type for http://tempuri.org/:ProjectSpecifi cDevice."

Any help would be greatly appreciated.
