Unity MVC using SOA and gereric Repository and UnitOfWork - asp.net-mvc

Question

I am trying to put together a project that is based on SOA and uses Gereric Repository and UnitOfWork along with Unity.
My problem is that when the controllers try to initialize I get the following error:
The type String cannot be constructed. You must configure the container to supply this value.
I have the following Unity Configuration:
public static class UnityConfig
{
#region Unity Container
private static Lazy<IUnityContainer> container = new Lazy<IUnityContainer>(() =>
{
var container = new UnityContainer();
RegisterTypes(container);
return container;
});
/// <summary>
/// Gets the configured Unity container.
/// </summary>
public static IUnityContainer GetConfiguredContainer()
{
return container.Value;
}
#endregion
public static void RegisterTypes(IUnityContainer container)
{
// register all your components with the container here
// it is NOT necessary to register your controllers
// e.g. container.RegisterType<ITestService, TestService>();
container.RegisterType<IDataContextAsync, MyDbContext>(new PerRequestLifetimeManager())
.RegisterType<IRepositoryProvider, RepositoryProvider>(
new PerRequestLifetimeManager(),
new InjectionConstructor(new object[] { new RepositoryFactories() })
)
.RegisterType<IUnitOfWorkAsync, UnitOfWork>(new PerRequestLifetimeManager())
.RegisterType<IUnitOfWork, UnitOfWork>(new PerRequestLifetimeManager())
.RegisterType<IRepositoryAsync<ApplicationSetting>, Repository<ApplicationSetting>>()
.RegisterType<IApplicationSettingService, ApplicationSettingService>();
container.RegisterType<IRepositoryProvider, RepositoryProvider>(new InjectionConstructor(container));
}
}
The following Activator
using System.Linq;
using System.Web.Mvc;
using Microsoft.Practices.Unity.Mvc;
using XNETProductQuote.Web;
[assembly: WebActivatorEx.PreApplicationStartMethod(typeof(UnityWebActivator), "Start")]
[assembly: WebActivatorEx.ApplicationShutdownMethod(typeof(UnityWebActivator), "Shutdown")]
namespace XNETProductQuote.Web
{
/// <summary>Provides the bootstrapping for integrating Unity with ASP.NET MVC.</summary>
public static class UnityWebActivator
{
/// <summary>Integrates Unity when the application starts.</summary>
public static void Start()
{
var container = UnityConfig.GetConfiguredContainer();
FilterProviders.Providers.Remove(FilterProviders.Providers.OfType<FilterAttributeFilterProvider>().First());
FilterProviders.Providers.Add(new UnityFilterAttributeFilterProvider(container));
DependencyResolver.SetResolver(new UnityDependencyResolver(container));
// TODO: Uncomment if you want to use PerRequestLifetimeManager
Microsoft.Web.Infrastructure.DynamicModuleHelper.DynamicModuleUtility.RegisterModule(typeof(UnityPerRequestHttpModule));
}
/// <summary>Disposes the Unity container when the application is shut down.</summary>
public static void Shutdown()
{
var container = UnityConfig.GetConfiguredContainer();
container.Dispose();
}
}
}
My controller that I am trying to load is the following
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using XNETProductQuote.Entities ;
using XNETProductQuote.Entities.Models;
using XNETProductQuote.Service;
namespace XNETProductQuote.Controllers
{
public class ApplicationSettingController : Controller
{
private IApplicationSettingService service;
public ApplicationSettingController(IApplicationSettingService svr)
{
service = svr;
}
//
// GET: /ApplicationSetting/
public ActionResult Index()
{
var applicationSettings = service.GetAll();
return View(applicationSettings);
}
}
As far as I can see the Unityconfig Registers the IApplicationSettingService type that should be used to initialise the controller.
am I missing something else?
UPDATE:
The error I get is
[InvalidOperationException: The type String cannot be constructed. You must configure the container to supply this value.]
