Ninject 3.0MVC kernel.bind错误自动注册

Question

kernel.Bind(scanner =>上的获取和错误..。在VS 2010中，“扫描器”在它下面有一个小的错误行。

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

键入自动注册，就像2.0中的旧kernel.scan。我不知道我做错了什么。添加并移除了这么多Ninject软件包。完全迷失了，浪费了很多时间。

Answer 1

你必须取消评论

//using Ninject.Extensions.Conventions;

Answer 2

只是想压缩一些我需要的程序集，以消除我的错误。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

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

这是我的完整代码，这是有效的。希望能帮助到lse。
