不支持服务类型IAssembliesResolver。参数名称：serviceType

Question

我在尝试连接Simple Injector和web api

时遇到了一些问题

我得到的错误是：

  

不支持服务类型IAssembliesResolver。参数名称：   的serviceType

当我尝试使用simpleinjector和web api（nuget）集成库附带的扩展方法注册控制器时，它会引发异常

container.RegisterWebApiControllers(GlobalConfiguration.Configuration);

我刚刚修改了代码以覆盖IAssemblyResolver，但它没有工作

public static void Initialize()
    {
        GlobalConfiguration.Configuration.Services
        .Replace(typeof(IAssembliesResolver),
            new CustomAssembliesResolver());

        var container = new Container();

        InitializeContainer(container);

        container.RegisterWebApiControllers(GlobalConfiguration.Configuration);

        container.Verify();

        GlobalConfiguration.Configuration.DependencyResolver =
            new SimpleInjectorWebApiDependencyResolver(container);
    }

我从this question获取了自定义程序集解析程序，我只是将其指向bin文件夹

public class CustomAssembliesResolver:DefaultAssembliesResolver
    {
        public override ICollection<Assembly> GetAssemblies()
        {
            var appPath = AppDomain.CurrentDomain.BaseDirectory;

            var  plugins = (
             from file in Directory.GetFiles(
                 appPath + "\\bin", "*.dll",
                 SearchOption.AllDirectories)
             let assembly = Assembly.LoadFile(file)
             select assembly)
             .ToArray();    

            return base.GetAssemblies()
                .Union(plugins).ToArray();
        }
    }

任何想法？

更新：

这是堆栈：

经过几个小时的挣扎，我得到了这个例外：

  

未找到入口点

原来，这个绑定重定向丢失了

<assemblyIdentity name="System.Web.Http" publicKeyToken="31bf3856ad364e35" culture="neutral" />
  <bindingRedirect oldVersion="0.0.0.0-6.0.0.0" newVersion="5.0.0.0" />
  </dependentAssembly>

感谢@steven帮我指出解决这个问题的方向

我删除了CustomAssembliesResolver，现在一切正常！
