I think you are missing some stuff regarding your DependencyScope. I use
Windsor, but here's my setup.
Global.asax
public class MvcApplication : System.Web.HttpApplication
{
public static String sessionkey = "current.session";
public static String transactionkey = "current.transaction";
public static IWindsorContainer Container;
public static ISessionFactory SessionFactory { get; set; }
protected void Application_Start()
{
AreaRegistration.RegisterAllAreas();
WebApiConfig.Register(GlobalConfiguration.Configuration);
FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
RouteConfig.RegisterRoutes(RouteTable.Routes);
BundleConfig.RegisterBundles(BundleTable.Bundles);
AuthConfig.RegisterAuth();
Version version =
Assembly.GetExecutingAssembly().GetName().Version;
Application["Version"] = String.Format("{0}.{1}",
version.Major, version.Minor);
//make ASP.NET use castle container to create controllers
//this way we can inject NHibernate session into controllers
//create empty container
//scan this prject for Installers and install all the types in
the container
Container = new WindsorContainer().Install(FromAssembly.This());
//webapi controllers are different. they use the
DependencyResolver, not a ControllerFactory
GlobalConfiguration.Configuration.DependencyResolver = new
WindsorDependencyResolver(Container.Kernel);
//tell ASP.NET to get its controllers from Castle
ControllerBuilder.Current.SetControllerFactory(new
WindsorControllerFactory(Container.Kernel));
//initialize NHibernate
var nh = new NHInit();
nh.Initialize();
nh.InitializeAudit();
SessionFactory = nh.SessionFactory;
//tell container to return SessionFactory.GetCurrentSession()
every time ISession is requested
Container
.Register(Component.For<ISession>().UsingFactoryMethod(()
=> MvcApplication.CurrentSession)
.LifeStyle
.PerWebRequest);
}
protected void Application_OnEnd()
{
//dispose Castle container and all the stuff it contains
Container.Dispose();
}
public static ISession CurrentSession
{
get { return (ISession)HttpContext.Current.Items[sessionkey]; }
set { HttpContext.Current.Items[sessionkey] = value; }
}
protected void Application_BeginRequest()
{
CurrentSession = SessionFactory.OpenSession();
}
protected void Application_EndRequest()
{
if (CurrentSession != null)
CurrentSession.Dispose();
}
}
WindsorDependencyResolver.cs
public class WindsorDependencyResolver :
System.Web.Http.Dependencies.IDependencyResolver
{
private readonly IKernel _kernel;
public WindsorDependencyResolver(IKernel kernel)
{
_kernel = kernel;
}
public IDependencyScope BeginScope()
{
return new WindsorDependencyScope(_kernel);
}
public Object GetService(Type serviceType)
{
return _kernel.HasComponent(serviceType)
? _kernel.Resolve(serviceType)
: null;
}
public IEnumerable<Object> GetServices(Type serviceType)
{
return _kernel.ResolveAll(serviceType).Cast<Object>();
}
public void Dispose()
{
_kernel.Dispose();
}
}
WindsorDependencyScope.cs
public class WindsorDependencyScope : IDependencyScope
{
private readonly IKernel _kernel;
private readonly IDisposable _scope;
public WindsorDependencyScope(IKernel kernel)
{
_kernel = kernel;
_scope = kernel.BeginScope();
}
public object GetService(Type serviceType)
{
return _kernel.HasComponent(serviceType) ?
_kernel.Resolve(serviceType) : null;
}
public IEnumerable<object> GetServices(Type serviceType)
{
return _kernel.ResolveAll(serviceType).Cast<object>();
}
public void Dispose()
{
_scope.Dispose();
}
}
ApiControllersInstaller.cs
public class ApiControllersInstaller : IWindsorInstaller
{
public void Install(IWindsorContainer container,
IConfigurationStore store)
{
container.Register(Classes.FromThisAssembly()
.BasedOn<ApiController>()
.LifestylePerWebRequest());
}
}
