Question

我看过几个涉及这个问题的问题;但似乎没有一个匹配或修复我的情况。在我的开发机器上，我没有任何问题。当我部署（到IIS 8.5，Server 2012 R2）时，我开始得到可怕的无参数构造函数错误。这是我正在使用的一些代码。

public class ReportController : BaseController
{
    public ReportController(KestrelContext ctx) : base(ctx) { }
}

我从中得到的基本控制器是......

public class BaseController : Controller
{
    protected KestrelContext db;

    public BaseController(KestrelContext ctx)
    {
        db = ctx;
    }
}

和NinjectWebCommon.cs ....

[assembly: WebActivatorEx.PreApplicationStartMethod(typeof(KestrelAdmin.App_Start.NinjectWebCommon), "Start")]
[assembly: WebActivatorEx.ApplicationShutdownMethodAttribute(typeof(KestrelAdmin.App_Start.NinjectWebCommon), "Stop")]

namespace KestrelAdmin.App_Start
{
    using System;
    using System.Web;

    using Microsoft.Web.Infrastructure.DynamicModuleHelper;

    using Ninject;
    using Ninject.Web.Common;
    using KestrelAdmin.Models;

    public static class NinjectWebCommon 
    {
        private static readonly Bootstrapper bootstrapper = new Bootstrapper();

        /// <summary>
        /// Starts the application
        /// </summary>
        public static void Start() 
        {
            DynamicModuleUtility.RegisterModule(typeof(OnePerRequestHttpModule));
            DynamicModuleUtility.RegisterModule(typeof(NinjectHttpModule));
            bootstrapper.Initialize(CreateKernel);
        }

        /// <summary>
        /// Stops the application.
        /// </summary>
        public static void Stop()
        {
            bootstrapper.ShutDown();
        }

        /// <summary>
        /// Creates the kernel that will manage your application.
        /// </summary>
        /// <returns>The created kernel.</returns>
        private static IKernel CreateKernel()
        {
            var kernel = new StandardKernel();
            try
            {
                kernel.Bind<Func<IKernel>>().ToMethod(ctx => () => new Bootstrapper().Kernel);
                kernel.Bind<IHttpModule>().To<HttpApplicationInitializationHttpModule>();

                RegisterServices(kernel);
                return kernel;
            }
            catch
            {
                kernel.Dispose();
                throw;
            }
        }

        /// <summary>
        /// Load your modules or register your services here!
        /// </summary>
        /// <param name="kernel">The kernel.</param>
        private static void RegisterServices(IKernel kernel)
        {
            kernel.Bind<KestrelContext>().ToSelf().InRequestScope();
        }        
    }
}

目标框架一直是.NET 4.5 - 而不是4.5.x，只有4.5。在packages.config中验证了依赖项。所有文件的权限似乎都是正确的。

任何帮助非常赞赏。

更新：我完全没有想法。我可以说，当我部署到IIS 8.5时，NinjectWebCommon类未成功初始化NinjectHttpModule。我将在这里包含我的包配置，并希望有人能指出我正确的方向。

另外，我尝试了here（使用github二进制文件）描述的备用设置，但这导致了相同的错误。所以现在我真的很困惑。

I still don't know what's going on, but somehow I've fixed this. Here's some information on my final configuration. Maybe this will help someone else. I'm sorry I can't be more help; but this just started working for me.
