Simple Registration of Services and Controller for ASP.MVC 3 with StructureMap

ControllerRegistryConvention.cs

using System;
using System.Web.Mvc;
using StructureMap.Configuration.DSL;
using StructureMap.Graph;

namespace NewInMVC3.Infrastructure
{
    internal class ControllerRegistryConvention : IRegistrationConvention
    {
        public void Process(Type type, Registry registry)
        {
            if (!type.IsAbstract && typeof(IController).IsAssignableFrom(type))
            {
                registry.AddType(type, type);
            }
        }
    }
}

RegisterStructureMap.cs

using System.Web.Mvc;

namespace NewInMVC3.Infrastructure
{
    internal static class RegisterStructureMap
    {
        public static void Execute()
        {
            var container = new StructureMap.Container();

            container.Configure(c =>

                    x.AssembliesFromApplicationBaseDirectory();
                    x.WithDefaultConventions();
                    x.AddAllTypesOf<ModelValidatorProvider>();

            });

            DependencyResolver.SetResolver(new StructureMapDependencyResolver(container));
            FilterProviders.Providers.Add(new StructureMapFilterAttributeFilterProvider(container));
        }
    }
}

StructureMapDependencyResolver.cs

        }
    }

StructureMapFilterAttributeFilterProvider.cs
