kernel.Bind( scanner => ... "scanner" 在 VS 2010 中有一条小错误行。

无法将 lambda 表达式转换为类型“System.Type[]”，因为它不是委托类型

像 2.0 中的旧 kernel.scan 一样尝试自动注册。我无法弄清楚我做错了什么。添加和删​​除了许多 Ninject 包。完全迷失了，变得非常浪费时间。

你必须取消注释

//using Ninject.Extensions.Conventions;

只是想浓缩一些我需要摆脱我的错误的程序集。谢谢雷莫斯

using System.Linq;  //correct the .Any() error in the IsServiceType
using Ninject;
using Ninject.Web.Common;
using Ninject.Extensions.Conventions; //Corrected the error with kernel.bind

更改了 .BindToDefaultInterface() --> .BindDefaultInterface()

这是我的完整代码，这是有效的。希望能帮助别人。
