WebForms 中的 Ninject 3

Question

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

“静态容器已经有一个与之关联的内核！”

我在 Global.asax 中实现 Ninject，继承自 NinjectHttpApplication 并覆盖 CreateKernel()，我的模块采用以下形式

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

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

疼痛的黄屏说

有什么想法吗？

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

这是您注册绑定的地方，而不是 Global.asax
