I am trying to access the WCF service having following interface and implementation:

[ServiceContract(Namespace="http://SMS.com/OPS")]
public interface IOrderProcessingService
{
[UseNetDataContractSerializer]
[OperationContract]
Customer GetAnyCustomer();

[UseNetDataContractSerializer]
[OperationContract]
Customer GetCustomerByName(string customerName);
}

public class OrderProcessingService : IOrderProcessingService
{
public Customer GetAnyCustomer()
{
ICustomerRepository repository = new CustomerRepository();
return repository.GetByName(”Tom”);
}

public Customer GetCustomerByName(string customerName)
{
ICustomerRepository repository = new CustomerRepository();
return repository.GetByName(customerName);

}
}

CustomerRepository class is accessing the database using NHibernate.

Now the problem is that the method GetAnyCustomer() is working fine. But when the service client is accessing the method GetCustomerByName, the following exception is thrown, indicating that there is some problem in deserializing the given string parameter customerName. The exception details are as follows:

WorkingWithGraph.Tests.OrderProcessingServiceTest.GetCustomerByNameTest : System.ServiceModel.FaultException : The formatter threw an exception while trying to deserialize the message: There was an error while trying to deserialize parameter http://SMS.com/OPS:customerName. The InnerException message was ‘Error in line 1 position 281. XML ‘Element’ ‘http://SMS.com/OPS:customerName’ does not contain expected attribute ‘http://schemas.microsoft.com/2003/10/Serialization/:Type’. The deserializer has no knowledge of which type to deserialize. Check that the type being serialized has the same contract as the type being deserialized.’. Please see InnerException for more details.

And what does it meant by : XML ‘Element’ ‘http://SMS.com/OPS:customerName’ does not contain expected attribute ‘http://schemas.microsoft.com/2003/10/Serialization/:Type’

I have also tried encapsulating the customerName both in a DataContract and in a MessageContract and used these contracts as parameter types, but not to avail anything.

Please help me.

Thanks in advance.

(No, the problem was not related to Antlr3; the exception really said that NHibernate or one of its assemblies could not be loaded).
In my configSection, I did not specify an exact version. I have referenced the NHibernate assembly from the GAC. Copy local has been set to false on my reference; apparently, the CLR was not able to exactly determine which NHibernate assembly should be loaded. So, I’ve solved it by setting ‘Copy Local’ to true on my NHibernate reference).

Anyway, interesting blog.

is that what you’re getting?

Now I got to say this… Getz orfffzz mee land (the land in front of the natural pool belongs to my parents ^^ )

Another thing is that your Cache isn’t checking for semantically equal objects.

Have fun

Enjoy!
