I know this question has been asked many times,but after reading all those SO similar questions i am not able to track my error.I have put the debugger in My controller's Constructor(ClaimAuditAdminController) but debugger doesn't goes there.
My Route.Config is
public class RouteConfig
{
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "ClaimAuditAdmin", action = "DisplayClaimAuditView", id = UrlParameter.Optional }
);
}
and the screen shot of my error is

activator trying to create ur controller with parametrless constructor. but while your controller constructor has parameter
public ClaimAuditAdminController(IClaimsAuditAdminRepository claimAuditAdminRepository) <--this place
{
this.claimAuditAdminRepository = claimAuditAdminRepository;
}
the exception occurs.
Try to remove param from constructor or try override the DefaultControllerFactory
and create controller with parameter.

I have this controller as you can see :
namespace Web.Front.Controllers
{
public class CarController : Controller
{
ICarService _CarService;
public CarController(ICarService carService)
{
_CarService = carService;
}
// GET: Car
public ActionResult Index()
{
return View();

As a note i am using ninject to inject services to controllers .when i remove the service from constructor it works .
The ninject code:
private static void RegisterServices(IKernel kernel)
{
kernel.Bind<DidbaanContext>().To<DidbaanContext>();
kernel.Bind<ICarService>().To<CarService>();
kernel.Bind<ICarRepository>().To<CarRepository>();
}
mvc needs parameterless contructions.
If you have no constructor, .Net-runtime create parameterless contruction automaticly, otherwise if you have a contruction with parameter, than the runtime don't do that and raise an error.
Ether you create a new carService on each controler, or you use a serviceProvider.
The unittest are simple with a serviceprovider.
With asp.net core its easy enter link description here, if you use mvc 4 or 5. you can see here a see here a sample enter link description here
I'm trying to use a fairly simple generic repository for a number of administration lists in an application. Functionality for the admin users is just CRUD to keep the lists up to date for use elsewhere as lookups.
I keep getting an error of the form:
An error occurred when trying to create a controller of type
'WhatWorks.Controllers.AchievementController'. Make sure that the
controller has a parameterless public constructor.
I've read an awful lot of posts on SO and blogs found through Google but I can't find an answer (at least nothing that makes sense to me as an answer which may be another problem...)
My code is as follows:
Controller
public class AchievementController : BootstrapBaseController
{
private readonly IAdminRepository<tAchievement> _repo;
public AchievementController(IAdminRepository<tAchievement> _repo)
{
this._repo = _repo;
}
ViewModel
public partial class AchievementListViewModel
{
public int Id { get; set; }
public string achievement { get; set; }
}
Interface
public interface IAdminRepository<TEntity> : IDisposable
where TEntity : class
{
IEnumerable<TEntity> Get();
TEntity GetByID(int id);
void Insert(TEntity entity);
void Delete(TEntity entity);
void Update(TEntity entity);
void Save();
}
Repository
public class AdminRepository<T> : IAdminRepository<T>
where T : class
{
private WhatWorksEntities objContext;
public AdminRepository()
{
objContext = new WhatWorksEntities();
}
public IEnumerable<T> Get()
{
return objContext.Set<T>().ToList();
}
etc.
Binding
kernel.Bind(typeof(IAdminRepository<>)).To(typeof(AdminRepository<>));
I've also tried binding with an additional line to no effect:
kernel.Bind<IAdminRepository<tAchievement>>().To<AdminRepository<tAchievement>>();
I'm assuming I'm missing something simple.
I have Ninject, Ninject.Web.MVC and Ninject.Web.Common in my references - all taken from NuGet.

_____________EDIT with partial answer_____________
Having recreated a project from scratch and hit the same error I noticed that the versions of a few of the additional packages I was using had changed. I'm using "Twitter Bootstrap for MVC" by Eric Hexter as my main display and this is pulling in a later version of Twitter Bootstrap than I've used previously. I'm not sure if this is causing the problem but the layout of the folders in an older working project are different from the new one.
This answer has given me a decent pointer after the comments by Trevor Pilley:
Ninject + MVC3 is not injecting into controller
In my older working project the following was in the Web.config file but is not in the new project. If I add it, the code works but there is still a problem with the Twitter Bootstrap layout - probably from the new .css files - I'll leave the question open for in case anyone can improve on this as an answer.

You need to tell the MVC runtime to use Ninject to resolve your controllers, the easiest way to do this is install the MVC extension for Ninject

routes.MapRoute(

}
}
RouteDebugger returns TRUE for the routes {controller}/{action} and {*catchall} and confirms the AppRelativeCurrentExecutionFilePath as: ~/Home
I have debugged the code and I can successfully debug and step into the HomeController constructor and Index action method. I have also been able to step into the "~/Views/Home/Index.cshtml" however it throws the exception at the line of code:
<span class="username">#Model.UserName</span>
Funnily enough, before I step into this code I can add "#Model.UserName" to my list of watches and I can see the object and its properties fine, but for some reason it throws an exception when stepping into or over this line of code.
If the debugger steps into the HomeController, the Index action method and the Index view, then why is it all of a sudden throwing the exception it can't find the HomeController for the path "~/Home"?
The captured fiddler data can be found at the following link: http://d-h.st/IqV
I have used Razor Generator to compile my views and I am also using Ninject.Mvc to resolve my controllers. It's also worth mentioning I have cleared down and re-generated the compiled views and my project does not contain any registered areas.
Any idea's? this might be simple or an obvious one but I'm new to MVC and am reading/learning as I go.
Thanks
So people can see this question was answered here is why it was throwing the exception and how I fixed it:
The exception was being thrown because of the following line of code in the HomeController Index view:
<i class="icon-key"></i> Log Out
As you can see it's passing the wrong arguments and "Log Out" is being passed in as the action name when infact this should be "Logout". I correct it to the following and it worked:
<i class="icon-key"></i> Log Out
So if you're getting this exception and like me can't understand why then please make sure you check the rest of your code in your view to make sure it is correct. In this instance the framework doesn't provide a meaning exception message and stacktrace.
Is there a way to enable injection in controllers loaded via builder.RegisterControllers() in an external assembly? When I copy the exact same assembly in my plugin folder, I get a parameterless constructor not found error.
// This doesnt work, parameterless constructor not found!
var assemblies = new DirectoryInfo(
HttpContext.Current.Server.MapPath("~/App_Plugins/"))
.GetFiles("*.dll")
.Select(r => Assembly.LoadFrom(r.FullName)).ToArray();
// This works, injection happens correctly on constructor
var assemblies = new[] {typeof (MvcApplication).Assembly};
The second one will work, while the first one will produce the error. I have tried manualy also registering the "external" controllers but still the same problem:
builder.RegisterAssemblyTypes(assemblies)
.Where(r => r.BaseType == typeof(Controller))
.InstancePerHttpRequest();
I am using the DefaultControllerFactory of mvc 4

Verify you are setting the DependencyResolver.
DependencyResolver.SetResolver(new AutofacDependencyResolver(ApplicationContainer));
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.

Thanks for correct answers.
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.
try adding this class as your ControllerFactory, I've actually seen the error above in MVC3 and this usually fixed it for me
public class StructureMapControllerFactory : DefaultControllerFactory
{
protected override IController GetControllerInstance(RequestContext requestContext, Type controllerType)
{
try
{
return (controllerType == null)
? base.GetControllerInstance(requestContext, controllerType)
: ObjectFactory.GetInstance(controllerType) as IController;
}
catch (Exception ex)
{
return null;
}
}
}
Using StructureMap.MVC5.Update I had to do this or else the nested IContainer was already disposed (weird) :
public class StructureMapControllerActivator : IControllerActivator
{
public IController Create(RequestContext requestContext, Type controllerType)
{
return StructuremapMvc.StructureMapDependencyScope.GetInstance(controllerType) as IController;
}
}
