ninject

问题 I'm trying to do a bit of a balancing act here. Currently Azure WebJobs don't support .NET Core. With some help, I created a .NET Core Console App and made it work as a WebJob. On top of that I'm trying to implement Ninject for DI. Code compiles fine but when I run it, I'm getting the "No parameterless constructor is defined for this object." error -- see below. I may be in a bit of unchartered territory here with Azure WebJobs, .NET Core 2.0 and Ninject but any idea what may be causing this?

问题 Having trouble getting the value of a ConstructorArgument parameter passed to kernel.Get(). I want to use the parameter's value to determine which of two string values will be passed into the constructor. The parameter is in fact there when expected, I just can't get at its value. I end up with a null ref exception after calling the parameter's GetValue method: namespace MyNS.DBProviders { public abstract class DBProviderBase { private ObjectContext _db; public DBProviderBase(ObjectContext db

问题 I'm current writing a Windows Service which connects to an existing service layer using Entity Framework (DbContext), and Ninject to inject the Respositories and DbContext instance. This is pretty much working with one caveat - I want a brand new DbContext instance each time the thread runs, whereas at the moment I'm getting the same one for the entire thread lifetime. My binding looks like this: Bind<IDbContext>().To<EnterpriseDbContext>().InThreadScope(); Bind<IUserRepository>().To

问题 I've seen frameworks like Ninject as well as posts on Stack speak about self binding when using dependency injection frameworks like in the code below. Bind<Samurai>().To<Samurai>(); They even go to the extent of having special syntax for this: Bind<Samurai>().ToSelf(); Why would you want to bind a type to itself? I don't see any practical applications for where this might be useful and help reduce dependencies in code. Wouldn't this just mean a reference to a type would simply resolve to

问题 I've upgraded MVC3 from RC2 to RTM. We were using Ninject 2.1.0.76, but things stopped working once I upgraded. So I used the NuGet manager to get the latest Ninject, Ninject.MVC3 and Ninject.Web.Mvc libraries (2.1.0.91, 1.0.0.0 and 2.1.0.39 respectively). Now, it creates an AppStart_NinjectMVC3 file. I removed NinjectHttpApplication from my global.asax and made it back into a regular HttpApplication. When I tried to build, I get; "Exception has been thrown by the target of an invocation"

问题 I setup a CustomRoleProver as: public class CustomRoleProvider : RoleProvider { private readonly IRepository<User> _repository; public CustomRoleProvider(IRepository<User> repository) { _repository = repository; } ... In my Global.asax.cs I have: //Create Ninject DI kernel var kernel = new StandardKernel(); kernel.Bind<IRepository<User>>().To<Repository<User>>(); //Tell ASP.NET MVC 3 to use our Ninject DI Container DependencyResolver.SetResolver(new NinjectDependencyResolver(kernel)); When I

问题 I'm testing Ninject, but following the how-to, i find it impossible to make it work. The information on the web is so messy even contradictory. I'm developping a website in MVC 4 on visual studio 2012 and i did install Ninject using Nuget. So I get an error : "No parameterless constructor defined for this object.". As soon as I enter my controller. I did the necessary steps : Nuget installation in NinjectWebCommon.cs, I did register my Interface in the RegisterServices method. In my

问题 I am using ninject in an asp.net web api project and have started receiving this intermittent ninject error: " Error loading Ninject component ICache No such component has been registered in the kernel's component container. " I'm using: Ninject 3.0.1.10 Ninject.MVC3 3.0.0.6 Ninject.Web.Common 3.0.0.7 They are all brought into my project with NuGet I load my Modules in IocConfig.RegisterIoc and have made no other changes or tweaks. It may be unrelated but the problem started occurring at

问题 I can't seem to get Ninject to dispose objects in request scope in an ASP.NET MVC application with web API no matter what I do. What I am doing: Create a new ASP.NET Web Application with Visual Studio 2013. I select the MVC template and add a Web API to it (it also has ASP.NET Identity in the package by default) I install Ninject.MVC5 package via nuget (install-package Ninject.MVC5) I add a the following class to my application: public class SomeDisposable : IDisposable { public void Dispose(
