Question

I’ve updated a project to VS2010 and MVC2 from VS2008 and MVC1. I’m having problems with Ninject not finding controllers within Areas

Here is my global.asax.cs file:

namespace Website
{
// Note: For instructions on enabling IIS6 or IIS7 classic mode, 
// visit http://go.microsoft.com/?LinkId=9394801

public class MvcApplication : NinjectHttpApplication
{
    public static StandardKernel NinjectKernel;

    public static void RegisterRoutes(RouteCollection routes)
    {
        routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

        routes.MapRoute(
            "Balance",
            "Balance/{action}/{month}/{year}",
            new { controller = "Balance", action = "Index", month = DateTime.Now.Month, year = DateTime.Now.Year }
        );

        routes.MapRoute(
            "Default",                                              // Route name
            "{controller}/{action}/{id}",                           // URL with parameters
            new { controller = "Login", action = "Index", id = "" }  // Parameter defaults
        );

    }

    /*
    protected void Application_Start()
    {
        AreaRegistration.RegisterAllAreas();

        RegisterRoutes(RouteTable.Routes);

        // initializes the NHProfiler so you can see what is going on with your queries
        HibernatingRhinos.Profiler.Appender.NHibernate.NHibernateProfiler.Initialize();
    }
    */

    protected override void OnApplicationStarted()
    {
        RegisterRoutes(RouteTable.Routes);
        AreaRegistration.RegisterAllAreas();
        RegisterAllControllersIn(Assembly.GetExecutingAssembly());
    }

    protected void Application_Error(object sender, EventArgs e)
    {
        var errorService = NinjectKernel.Get<IErrorLogService>();
        errorService.LogError(HttpContext.Current.Server.GetLastError().GetBaseException(), "AppSite");
    }

    protected override IKernel CreateKernel()
    {
        if (NinjectKernel == null)
        {
            NinjectKernel = new StandardKernel(new ServiceModule());
        }

        return NinjectKernel;
    }
}

public class ServiceModule : NinjectModule
{
    public override void Load()
    {
        Bind<IHelper>().To<Helper>().InRequestScope();
        Bind<IErrorLogService>().To<ErrorLogService>();

        Bind<INHSessionFactory>().To<NHSessionFactory>().InSingletonScope();
        Bind<ISessionFactory>().ToMethod(ctx =>
                                         ctx.Kernel.Get<INHSessionFactory>().GetSessionFactory())
                               .InSingletonScope();

        Bind<INHSession>().To<NHSession>();
        Bind<ISession>().ToMethod(ctx => ctx.Kernel.Get<INHSession>().GetSession());
    }
}
}

Accessing controllers within the /Controllers folder works OK, but accessing controllers within a /Areas/Member/Controller throws the following error:

Server Error in '/' Application.

Cannot be null

The Url for this request is /Member/Controller/, If I change the Url too /Controller the controller fires but I get an error that the system cannot find the View in the path /Views

When it should be looking in /Area/Members/Views

I have either done something wrong in the upgrade or I’m missing something bt I just can’t figure out what. I’ve been trying to figure this out for 3 days…

Update from the core, I just committed a fix: http://github.com/ninject/ninject.web.mvc
