WebForms中的Ninject 3

Question

当我尝试启动安装了WebForms ( Ninject.Web (v3) )的Ninject.Web应用程序时，会收到以下错误。

“静态容器已经有一个与它相关的内核了！”

我正在Global.asax中实现Ninject，从NinjectHttpApplication继承并覆盖CreateKernel()，我的模块如下所示

public class NinjectWebModule: NinjectModule
    {
        public override void Load()
        {
            Bind<IBlah>().To<Blah>();
        }
    }

我基本上遵循了包含How can I implement Ninject or DI on asp.net Web Forms?的设置建议

黄色的痛苦屏幕上写着

有什么想法吗？

哈！安装Ninject.Web (v3)添加一个带有NinjectWebCommon.cs的App_Start文件夹

这是您注册绑定的地方，而不是在Global.asax中。
