Problem integrating WCF with Sharp architecture

Question

I'm working with an application which uses wcf and sharp architecture, I'm trying to create a service to write to the database. Here is my service:

[ServiceContract]
public interface IFacilitiesWcfService : ICloseableAndAbortable
{
    [OperationContract]
    void AddFacility(string facility);

}

[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
class FacilitiesWcfService:IFacilitiesWcfService
{
    public FacilitiesWcfService(IRepositoryWithTypedId<Facility,string> facilityRepository)
    {
        Check.Require(facilityRepository != null, "facilityRepository may not be null");

        this.facilityRepository = facilityRepository;
    }
    private readonly IRepositoryWithTypedId<Facility,string> facilityRepository;

    public void AddFacility(string facility)
    {
        facilityRepository.DbContext.BeginTransaction();

        Facility newFacility = new Facility();
        newFacility.SetAssignedIdTo(facility);
        newFacility.NAME=facility;
        newFacility.ADDRESS = facility;

        facilityRepository.DbContext.CommitTransaction();
    }
    public void Abort() { }

    public void Close() { }
}

And the LogisticsWCF.svc file in the web project:

<%@ ServiceHost Language="C#" Debug="true" Service="Project.Wcf.FacilitiesWcfService"
 Factory="SharpArch.Wcf.NHibernate.ServiceHostFactory, SharpArch.Wcf" %>

I created a client with svcutil.exe http://localhost:1905/LogisticsWCF.svc?wsdl and then created this test case:

[TestFixture]
class WCFLogisticsTests
{
    [Test]
    public void CanAddFacility()
    {

        FacilitiesWcfServiceClient facility = new FacilitiesWcfServiceClient();
        facility.AddFacility("NEW");
        facility.Close();
    }
}

But I get this exception:

TestCase 'Tests.Project.Web.WCFLogisticsTests.CanAddFacility'
failed: System.ServiceModel.FaultException`1[System.ServiceModel.ExceptionDetail] : The needed dependency of type FacilitiesWcfService could not be located with the ServiceLocator. You'll need to register it with the Common Service Locator (CSL) via your IoC's CSL adapter.

I think I'm missing some configuration of sharp architecture, because when I don't use Factory="SharpArch.Wcf.NHibernate.ServiceHostFactory, SharpArch.Wcf" in the .svc file I don't get the exception, but I'm not able to write anything to the database ( I get an ISession not configured exception).

I tried to follow the Northwind example, but it's not working, What can I be missing?

Answer 1

You're not returning anything from your service method, so it needs to be marked as IsOneWay=true:

[ServiceContract]
public interface IFacilitiesWcfService : ICloseableAndAbortable
{
    [OperationContract(IsOneWay=true)]
    void AddFacility(string facility);

}

By default, WCF expects request/response, i.e. it expects to get a response back from the service method. "void" doesn't count as a response - so just mark those service methods that don't return anything with the IsOneWay=true and you should be fine.

Answer 2

Finally I've found the answer, I was missing the following line in the ComponentRegistrar:

container.AddComponent("facilityWcfService", typeof(FacilitiesWcfService));

Answer 3

Can you please tell me where you added this line in your CompnentRegistrar as I am having the same issue, and cannot get it resolved.
