How to get ServiceStack to receive XML request from TFS with XML namespaces

How to get ServiceStack to receive XML request from TFS with XML namespaces

I am trying to wire up TFS 2012 event notifications to ServiceStack, but I
just keep getting the error:
{
"responseStatus": {
"errorCode": "RequestBindingException",
"message": "Unable to bind request",
"stackTrace": "at
ServiceStack.WebHost.Endpoints.RestHandler.GetRequest(IHttpRequest
httpReq, IRestPath restPath)\r\n
at
ServiceStack.WebHost.Endpoints.RestHandler.ProcessRequest
(IHttpRequest httpReq, IHttpResponse httpRes,
String operationName)"
}
}



Here is my DTO (It contains some bits that I have tried to make it work).
[Route("/releasemanagement/tfsevents/buildcomplete", "POST")]
[DataContract(Namespace = "http://www.w3.org/2001/XMLSchema-instance")]
public class TfsEventBuildComplete : IReturn<BuildCompleteResponse>
{
[DataMember]
public string BuildUri { get; set; }
[DataMember]
public string TeamFoundationServerUrl { get; set; }
[DataMember]
public string TeamProject { get; set; }
[DataMember]
public string Title { get; set; }
[DataMember]
public string Id { get; set; }
[DataMember]
public TfsEventStatusChange StatusChange { get; set; }
[DataMember]
public string ChangedBy { get; set; }
}
public class TfsEventStatusChange
{
public string FieldName { get; set; }
public string NewValue { get; set; }
}



Here is the XML that comes from TFS:
<BuildStatusChangeEvent xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<BuildUri>vstfs:///Build/Build/4799</BuildUri>
<TeamFoundationServerUrl>http://TFSURL:8080/tfs/collection</TeamFoundationServerUrl>
<TeamProject>iSAMS</TeamProject>
<Title>iSAMS Build Release_20130814.1 Quality Changed To Publish</Title>
<Subscriber>[02]\Project Collection Service Accounts</Subscriber>
<Id>Release_20130814.1</Id>
<Url>http://TFSURL:8080/tfs/web/build.aspx?pcguid=GUID&amp;builduri=vstfs:///Build/Build/4799</Url>
<TimeZone>GMT Daylight Time</TimeZone>
<TimeZoneOffset>+01:00:00</TimeZoneOffset>
<ChangedTime>8/14/2013 9:33:30 AM</ChangedTime>
<StatusChange>
<FieldName>Quality</FieldName>
<NewValue>Publish</NewValue>
</StatusChange>
<ChangedBy>DOMAIN\USER</ChangedBy>
</BuildStatusChangeEvent>
I think ServiceStack is effectively failing to deserialise the request due
to the namespacing, but I can't figure it out.
Most of what I have tried has come from here:
ServiceStack - xml deserializing only works with namespace in xml
