Обеспечение или Фильтрация блоков при регистрации областей для приложения ASP.NET MVC 2.0

Я собрал следующую утилиту, чтобы изолировать сборки для регистрации областей. Мне пришлось вырубить внутренности регистрации области, но они не кажутся ужасно сложными, и у меня это работает достаточно хорошо:

using System;
using System.Linq;
using System.Reflection;
using System.Web.Mvc;
using System.Web.Routing;

namespace MyCompany.Web.Mvc
{
    /// <summary>
    /// Provides helpful utilities for performing area registration, where <see cref="AreaRegistration.RegisterAllAreas()"/> may not suffice.
    /// </summary>
    public static class AreaRegistrationUtil
    {
        /// <summary>
        /// Registers all areas found in the assembly containing the given type.
        /// </summary>
        /// <typeparam name="T">A type that derives from <see cref="AreaRegistration"/> and has a default constructor.</typeparam>
        public static void RegisterAreasForAssemblyOf<T>()
            where T : AreaRegistration, new()
        {
            RegisterAreasForAssemblyOf<T>(null);
        }

        /// <summary>
        /// Registers all areas found in the assembly containing the given type.
        /// </summary>
        /// <typeparam name="T">A type that derives from <see cref="AreaRegistration"/> and has a default constructor.</typeparam>
        /// <param name="state">An object containing state that will be passed to the area registration.</param>
        public static void RegisterAreasForAssemblyOf<T>(object state)
            where T : AreaRegistration, new()
        {
            RegisterAreasForAssemblies(state, typeof (T).Assembly);
        }

        /// <summary>
        /// Registers all areas found in the given assemblies.
        /// </summary>
        /// <param name="assemblies"><see cref="Assembly"/> objects containing the prospective area registrations.</param>
        public static void RegisterAreasForAssemblies(params Assembly[] assemblies)
        {
            RegisterAreasForAssemblies(null, assemblies);
        }

        /// <summary>
        /// Registers all areas found in the given assemblies.
        /// </summary>
        /// <param name="state">An object containing state that will be passed to the area registration.</param>
        /// <param name="assemblies"><see cref="Assembly"/> objects containing the prospective area registrations.</param>
        public static void RegisterAreasForAssemblies(object state, params Assembly[] assemblies)
        {
            foreach (Type type in
                from assembly in assemblies
                from type in assembly.GetTypes()
                where IsAreaRegistrationType(type)
                select type)
            {
                RegisterArea((AreaRegistration) Activator.CreateInstance(type), state);
            }
        }

        /// <summary>
        /// Performs area registration using the specified type.
        /// </summary>
        /// <typeparam name="T">A type that derives from <see cref="AreaRegistration"/> and has a default constructor.</typeparam>
        public static void RegisterArea<T>()
            where T : AreaRegistration, new()
        {
            RegisterArea<T>(null);
        }

        /// <summary>
        /// Performs area registration using the specified type.
        /// </summary>
        /// <typeparam name="T">A type that derives from <see cref="AreaRegistration"/> and has a default constructor.</typeparam>
        /// <param name="state">An object containing state that will be passed to the area registration.</param>
        public static void RegisterArea<T>(object state)
            where T : AreaRegistration, new()
        {
            var registration = Activator.CreateInstance<T>();
            RegisterArea(registration, state);
        }

        private static void RegisterArea(AreaRegistration registration, object state)
        {
            var context = new AreaRegistrationContext(registration.AreaName, RouteTable.Routes, state);
            string ns = registration.GetType().Namespace;

            if (ns != null) context.Namespaces.Add(string.Format("{0}.*", ns));

            registration.RegisterArea(context);
        }

        /// <summary>
        /// Returns whether or not the specified type is assignable to <see cref="AreaRegistration"/>.
        /// </summary>
        /// <param name="type">A <see cref="Type"/>.</param>
        /// <returns>True if the specified type is assignable to <see cref="AreaRegistration"/>; otherwise, false.</returns>
        private static bool IsAreaRegistrationType(Type type)
        {
            return (typeof (AreaRegistration).IsAssignableFrom(type) && (type.GetConstructor(Type.EmptyTypes) != null));
        }
    }
}

Самый простой способ использовать это для меня -

AreaRegistrationUtil.RegisterAreasForAssemblyOf<SomeTypeInTargetAssembly>();

Это внесло заметные улучшения во время запуска, за счет невозможности зайти в область и автоматически зарегистрировать приложение. Однако в данном случае меня это не беспокоит.
