The problem of integrating WCF with Sharp architecture

Question

I am working with an application that uses wcf and a sharp architecture, I am trying to create a service for writing 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 CSL adapter.

I think I am missing some sharp architecture configuration, because when I do not use Factory="SharpArch.Wcf.NHibernate.ServiceHostFactory, SharpArch.Wcf" in the .svc file, I do not get an exception, but I can not write anything to the database (I get an exception other than ISession).

I tried to follow the example of Northwind, but it does not work, what can I lose?

Answer 1

Finally, I found the answer, I skipped the following line in ComponentRegistrar:

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

Answer 2

You are not returning anything from your service method, so you need to mark it as IsOneWay = true:

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

By default, WCF expects a request / response, that is, it expects a response from a service method. "void" is not considered an answer, so just mark those service methods that do not return anything with IsOneWay=true , and you should be fine.
