Structuremap does not work on MVC4

Question

I've used StructureMap in MVC2/3 many times without any concern, but I guess handling IoC is different in MVC4. When i used StructureMap for handling IoC in MVC4 I get the following exception.:

No parameterless constructor defined for this object

Why? I have not found any correct result in google except this: IoC Not Working In MVC4 These is my IoC classes:

public static class IoC {
    public static IContainer Initialize() {
        ObjectFactory.Initialize(x =>
                    {
                        x.Scan(scan =>
                        {
                            //scan.Assembly("DLL.Core");
                            scan.Assembly("DLL.CMS");
                            scan.TheCallingAssembly();
                            scan.WithDefaultConventions();
                        });
                        x.For<IDbContext>().Use<ModelEntities>();
                        x.For(typeof(IRepository<>)).Use(typeof(Repository<>));
                        x.For<IHttpControllerActivator>();
                        x.For<IController>();
                    });

        return ObjectFactory.Container;
    }

And SmDependencyResolver is:

    public class SmDependencyResolver : IDependencyResolver
{
    private readonly IContainer _container;

    public SmDependencyResolver(IContainer container)
    {
        _container = container;
    }

    public object GetService(Type serviceType)
    {
        if (serviceType == null) return null;
        try
        {
            return serviceType.IsAbstract || serviceType.IsInterface
                     ? _container.TryGetInstance(serviceType)
                     : _container.GetInstance(serviceType);
        }
        catch
        {

            return null;
        }
    }

    public IEnumerable<object> GetServices(Type serviceType)
    {
        return _container.GetAllInstances(serviceType).Cast<object>();
    }
}

And my error is:

No parameterless constructor defined for this object. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Thanks for correct answers.

Answer 1

oops.I found an emergency solution :) Try to implement a class from IControllerActivator

public class StructureMapControllerActivator : IControllerActivator
{
   private IContainer _container;
    
   public StructureMapControllerActivator(IContainer container)
   {
       _container = container;
   }
    
   public IController Create(RequestContext requestContext, Type controllerType)
   {
       return _container.GetInstance(controllerType) as IController;
   }
}

and then register it to the IoC class:

 x.For<IControllerActivator>().Use<StructureMapControllerActivator>();

and then enjoy it. Good luck

If you remove any old configuration for structuremap and install structurmap.mvc4 from nuget then configure your IoC container, you don't have any problems.
