500 Internal Server Error on a self hosted WCF Service

500 Internal Server Error on a self hosted WCF Service

I am attempting to develop a new WCF service that is hosted using the
ServiceHost object. I am able to get the console application to start and
I can see that it is binding to port 80 via netstat. Using WireShark I am
also able to see that the client is able to connect to that port and send
over the data. I had a problem early on with the amount of data that is
being sent in the SOAP message from the client, but was able to resolve
that issue by setting the max receive size on the binding. The HTTP 500
error that I am getting is:
The message with Action '' cannot be processed at the receiver, due to a
ContractFilter mismatch at the EndpointDispatcher. This may be because of
either a contract mismatch (mismatched Actions between sender and
receiver) or a binding/security mismatch between the sender and the
receiver. Check that sender and receiver have the same contract and the
same binding (including security requirements, e.g. Message, Transport,
None).
The following is my WCF code and my service code.
public class MyWCFService
{
private ServiceHost _selfHost;
public void Start()
{
Uri baseAddress = new Uri(@"http://192.168.1.10");
this._selfHost = new ServiceHost(typeof(MyServiceImpl), baseAddress);
try {
WebHttpBinding binding = new WebHttpBinding();
binding.MaxBufferSize = 524288;
binding.MaxReceivedMessageSize = 524288;
this._selfHost.AddServiceEndpoint(typeof(IMyServiceContract),
binding, "MyService");
ServiceMetadataBehavior smb = new ServiceMetadataBehavior();
smb.HttpGetEnabled = true;
this._selfHost.Description.Behaviors.Add(smb);
this._selfHost.Open();
}
catch ( CommunicationException ce ) {
this._selfHost.Abort();
}
}
public void Stop()
{
this._selfHost.Close();
}
}
The following is my service contract. It is fairly simple and only has a
single Operation. It is expected that it will be called upon the receipt
of a SOAP based message.
[ServiceContract(Namespace = "http://www.exampe.com")]
public interface IMyServiceContract
{
[OperationContract (Action="http://www.example.com/ReportData",
ReplyAction="*")]
string ReportData( string strReport );
}
The following the my implementation of the service contract
class MyServiceImpl : IMyServiceContract
{
public string ReportData( string strReport )
{
return "ok";
}
}
Here is what I am getting from my client (the strReport was very long so I
excluded it)
POST /MyService HTTP/1.1
Content-Type: text/xml; charset=utf-8
SOAPAction: "http://www.example.com/ReportData"
Host: 192.168.1.10
Content-Length: 233615
Expect: 100-continue
Connection: Keep-Alive
<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<soap:Body>
<ReportData xmlns="http://www.example.com/">
<strReport>
........
</strReport>
</ReportData>
</soap:Body>
</soap:Envelope>
Any help resolving this issue would be greatly appreciated.
