ninject

I have a class with a constructor having a parameter with a default value. With Ninject 2.2, it would honor the [Optional] attribute and work fine with no binding defined against a constructor declared like so: public EmployeeValidator([Optional] IValidator<PersonName> personNameValidator = null) Since upgrading to Ninject 3.0, construction of this object fails with a message stating that the provider returned null: Test method ValidatorIsolated.Tests.EmployeeValidatorTest.CreateEmployeeValidatorTest threw exception: Ninject.ActivationException: Error activating IValidator{PersonName} using

Long story short, I'm trying to use ELMAH with MVC 2 and Ninject, and I need to use parameterless constructors. I created an initial post about it here: Using a parameterless controller constructor with Ninject? I was advised to use property injection instead of constructor injection. So I moved from this: public class DepartmentsController : Controller { private IDepartmentsRepository departmentsRepository; public DepartmentsController(IDepartmentsRepository departmentsRepository) { this.departmentsRepository = departmentsRepository; } ... } to this: public class DepartmentsController :

In an MVC / WebAPI environment I would use InRequestScope to bind the DbContext . However, I am now on a Console application / Windows service / Azure worker role (doesn't really matter, just there's no Web request scope), which periodically creates a number of Tasks that run asynchronously. I would like each task to have its own DbContext , and since tasks run on their own thread, I tried binding DbContext using InThreadScope . Unfortunately, I realize that the DbContext is not disposed when a task is finished. What actually happens is, the thread returns to the Thread Pool and when it is

I'm using Ninject in an MVC project and I've used the autoregistration features in Ninject.Mvc and have my bindings set up in my application class. However, I have a place where I want to create an instance separate from those bindings. In StructureMap, you can do var foo = ObjectFactory.GetInstance<IFoo>(); and it will resolve it for you. Is there an equivalent in Ninject 2? I can't seem to find it anywhere. AFAIK, NInject doesn't have static method like this so all resolving should go to some kernel. But you can implement it easily; class ObjectFactory { static IKernel kernel = new

I'm struggling with the documentation to figure out exactly what I need to. The documentation (to my understanding) is for 1.5 anyway. N.B: I don't want to extend NinjectHttpApplication I've configured it to use the NinejctControllerFactory in Application_Start() but I get a null reference exception on the KernelContainer.Kernel when it tries to create a controller. Where do I configure the Kernel if I'm not extending NinjectHttpApplication? Take a look at this blog post. It should help clarify the process you need to perform on how to configure the kernel. http://www.kevinrohrbaugh.com/blog

I'm following a ninject filter attribute setup on this page . For them, they have: .WithConstructorArgumentFromControllerAttribute<LogAttribute>( "logLevel", attribute => attribute.LogLevel); The second parameter is expecting a Func<LogAttribute, object> callback . Their actual param list is setup as follows: Log(LogLevel = Level.Debug) But my filter attribute is setup as follows: public class AuthAttribute : FilterAttribute { } public class AuthFilter : IAuthorizationFilter { private readonly IUserService userService; private string[] roles; //Stuck on the constructor also. How do I accept
