不支持服务类型 IAssembliesResolver。参数名称：服务类型

Question

我在尝试连接 Simple Injector 和网络时遇到一些问题 api

我得到的错误是：

The service type IAssembliesResolver is not supported. Parameter name: serviceType

当我尝试使用 simpleinjector 和 web 集成库附带的扩展方法注册控制器时，它抛出了异常 api (nuget)

container.RegisterWebApiControllers(GlobalConfiguration.Configuration);

我刚刚修改了代码以覆盖 IAssemblyResolver，但它不起作用

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 中获取了自定义程序集解析器，我只是将它指向 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();
        }
    }

有什么想法吗？

经过几个小时的努力，我得到了这个异常：

Entry point was not found

结果发现绑定重定向丢失了

<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 帮我指出了解决这个问题的方向

我删除了 CustomAssembliesResolver，现在一切正常！
