Ninject Interception not working with MVC 5 - ninject

Question

I am trying to implement an InterceptAttribute which should intercept any method I add the attribute to. I have it working in a WebAPI solution, however, I cannot get it to work in an MVC 5 application. The code is the same in both projects. The following code is the attribute I created.
using Ninject;
using Ninject.Extensions.Interception;
using Ninject.Extensions.Interception.Attributes;
using Ninject.Extensions.Interception.Request;
namespace Questionnaire.Common.InterceptAttributes
{
public class InterceptCacheAttribute : InterceptAttribute
{
public double TimeOut { get; set; }
public override IInterceptor CreateInterceptor(IProxyRequest request)
{
var cacheInterceptor = request.Kernel.Get<CacheInterceptor>();
cacheInterceptor.TimeOut = TimeOut;
return cacheInterceptor;
}
}
}
The CacheInterceptor code is as follows:
using System;
using System.Text;
using Ninject;
using Ninject.Extensions.Interception;
using Ninject.Extensions.Interception.Request;
namespace Questionnaire.Common.Interceptors
{
public class CacheInterceptor : IInterceptor
{
[Inject]
public ICaching Cache { get; set; }
public double TimeOut { get; set; }
public void Intercept(IInvocation invocation)
{
var minutes = Cache.TimeOutMinutes;
if (Math.Abs(TimeOut - default(double)) > 0)
{
minutes = TimeOut;
}
invocation.ReturnValue = Cache.Get(GenerateCacheKey(invocation.Request), minutes, delegate
{
invocation.Proceed();
return invocation.ReturnValue;
});
}
private static string GenerateCacheKey(IProxyRequest request)
{
var sb = new StringBuilder(request.Method.Name).Append(".");
foreach (var argument in request.Arguments)
{
if (argument == null)
{
sb.Append("null");
}
else if (argument is string && argument.ToString().Length < 50)
{
sb.Append((string)argument);
}
else
{
sb.Append(argument.GetHashCode());
}
sb.Append(".");
}
sb.Remove(sb.Length - 1, 1);
return sb.ToString();
}
}
}
Finally I added the attribute to the following method.
using System.Configuration;
using Questionnaire.Common.InterceptAttributes;
namespace Questionnaire.Common.Utility
{
public class ConfigurationUtilities
{
[InterceptCache(TimeOut = 1440)]
public virtual string GetEnvironmentConnectionString(string name)
{
var connectionStringSettings = ConfigurationManager.ConnectionStrings[name + "_" + HostEnvironment];
return connectionStringSettings != null ? connectionStringSettings.ConnectionString : null;
}
}
}
Code execution never enters into the InterceptCacheAttribute class. I have put debug points within that class and the CacheInterceptor class and the debug points are never hit. The method the attribute is on executes just fine, but, I want it to be intercepted and that is not happening. I have the same code in a different project. That project is a WebAPI project which works great. The methods are intercepted and everything functions as it should. Can someone explain to me why I can't get it to work in the MVC 5 application? I would greatly appreciate it.
answer to BatteryBackupUnit's question:
The answer is I can't. The following is my NinjectWebCommon.cs class.
[assembly: WebActivatorEx.PreApplicationStartMethod(typeof(Mayo.Questionnaire.App_Start.NinjectWebCommon), "Start")]
[assembly: WebActivatorEx.ApplicationShutdownMethodAttribute(typeof(Mayo.Questionnaire.App_Start.NinjectWebCommon), "Stop")]
namespace Questionnaire.App_Start
{
using System;
using System.Web;
using System.Web.Http;
using System.Linq;
using ApplicationExtensions;
using Microsoft.Web.Infrastructure.DynamicModuleHelper;
using Ninject;
using Ninject.Web.Common;
public static class NinjectWebCommon
{
private static readonly Bootstrapper bootstrapper = new Bootstrapper();
public static void Start()
{
DynamicModuleUtility.RegisterModule(typeof(OnePerRequestHttpModule));
DynamicModuleUtility.RegisterModule(typeof(NinjectHttpModule));
bootstrapper.Initialize(CreateKernel);
}
public static void Stop()
{
bootstrapper.ShutDown();
}
private static IKernel CreateKernel()
{
var kernel = new StandardKernel();
try
{
kernel.Bind<Func<IKernel>>().ToMethod(ctx => () => new Bootstrapper().Kernel);
kernel.Bind<IHttpModule>().To<HttpApplicationInitializationHttpModule>();
GlobalConfiguration.Configuration.DependencyResolver = new NinjectDependencyResolver(kernel);
RegisterServices(kernel);
return kernel;
}
catch
{
kernel.Dispose();
throw;
}
}
private static void RegisterServices(IKernel kernel)
{
foreach (var module in from assembly in AppDomain.CurrentDomain.GetAssemblies()
select assembly.GetNinjectModules()
into modules
from module in modules
where !kernel.GetModules().Any(m => m.Name.Equals(module.Name))
select module)
{
kernel.Load(module);
}
}
}
}
Inside the RegisterServices method every assembly in the application is iterated over and any classes that inherit from NinjectModule are loaded. However, I can't verify that it is working because I can't debug it. I have tried, but, execution is never stopped within the class. I know that the class is being instantiated and that the modules are being loaded because I have bindings in those modules that are working, however, I can't verify it.
