Ninject，的WebAPI 2依赖注入不工作

我想Ninject在我的WebAPI 2项目整合，但我收到以下错误：Ninject，的WebAPI 2依赖注入不工作

{ 
    "message": "An error has occurred.", 
    "exceptionMessage": "An error occurred when trying to create a controller of type 'BrandController'. Make sure that the controller has a parameterless public constructor.", 
    "exceptionType": "System.InvalidOperationException", 
    "stackTrace": " at System.Web.Http.Dispatcher.DefaultHttpControllerActivator.Create(HttpRequestMessage request, HttpControllerDescriptor controllerDescriptor, Type controllerType)\r\n at System.Web.Http.Controllers.HttpControllerDescriptor.CreateController(HttpRequestMessage request)\r\n at System.Web.Http.Dispatcher.HttpControllerDispatcher.<SendAsync>d__1.MoveNext()", 
    "innerException": { 
     "message": "An error has occurred.", 
     "exceptionMessage": "Type 'ADAS.GoTango.WebApi.Controllers.BrandController' does not have a default constructor", 
     "exceptionType": "System.ArgumentException",

    } 
}

我的包的配置是：

<package id="Ninject" version="3.2.2.0" targetFramework="net45" /> 
<package id="Ninject.Web.Common" version="3.2.3.0" targetFramework="net45" /> 
<package id="Ninject.Web.Common.WebHost" version="3.2.3.0" targetFramework="net45" /> 
<package id="Ninject.Web.WebApi" version="3.2.4.0" targetFramework="net45" /> 
<package id="Ninject.Web.WebApi.WebHost" version="3.2.4.0" targetFramework="net45" /> 
<package id="Ninject.WebApi.DependencyResolver" version="0.1.4758.24814" targetFramework="net45" />

我的代码：

public class BrandController : BaseApiController 
{ 
    readonly BrandsBusiness _brandsBusiness; 

    public BrandController(BrandsBusiness brandsBusiness) 
    { 
     _brandsBusiness = brandsBusiness; 
    } 

    //public BrandController() 
    //{ 
    // _brandsBusiness = new BrandsBusiness(new BrandEfStore()); 
    //} 

    public IHttpActionResult Get() 
    { 
     try 
     { 
      var allActiveBrands = _brandsBusiness.GetAllActiveBrands(); 
      return Ok(allActiveBrands); 
     } 
     catch (Exception exception) 
     { 
      Logger.Error(exception); 
      return InternalServerError(); 
     } 
    } 

}

和NinjectWebCommon.cs文件

/// <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>(); 
     GlobalConfiguration.Configuration.DependencyResolver = new NinjectDependencyResolver(kernel); 

     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) 
{ 
    var configuration = new HttpConfiguration(); 
    kernel.Bind<DefaultModelValidatorProviders>().ToConstant(new DefaultModelValidatorProviders(configuration.Services.GetServices(typeof(ModelValidatorProvider)).Cast<ModelValidatorProvider>())); 
    kernel.Bind<BrandsBusiness>().ToSelf().InRequestScope(); 
    kernel.Bind<IBrandManagement>().To<BrandEfStore>().InRequestScope(); 
}

我已经试过alredy：

Parameterless constructor error with Ninject bindings in .NET Web Api 2.1

Ninject.ActivationException thrown only on first web request (WebAPI 2, OWIN 3, Ninject 3)

，但没有一次成功。
