我有这个用于上传文件的淘汰js脚本

当用户在上传控件中选择文件时,此代码会触发上载事件

Upload.html

    $(function() {
        var viewModel = {
            filename:  ko.observable(""),
        };

        ko.applyBindings(viewModel);
    });

<form>
<input id="upload" name="upload" 
    data-bind="fileUpload: { property: 'filename', url: 'http://localhost/api/upload/PostFormData' }" 
    type="file" /> 

<button id="submitUpload">Upload</button>
</form>

FileUpload.js

ko.bindingHandlers.fileUpload = {
init: function (element, valueAccessor) {
    $(element).after('<div class="progress"><div class="bar"></div><div class="percent">0%</div></div><div class="progressError"></div>');
},
update: function (element, valueAccessor, allBindingsAccessor, viewModel, bindingContext) {


    var options = ko.utils.unwrapObservable(valueAccessor()),
        property = ko.utils.unwrapObservable(options.property),
        url = ko.utils.unwrapObservable(options.url);



    if (property && url) {

        $(element).change(function() {
            if (element.files.length) {
                var $this = $(this),
                    fileName = $this.val(); …

我试图按照这个博客来实现与Unity的依赖注入,但我在boostrapper.cs中遇到错误(我使用Unity.MVC4库).有人能指出我在这里缺少什么吗？

错误:IoCContainer似乎没有实现Microsoft.Practices.ServiceLocation.IServiceLocator.参数名称:commonServiceLocator

 public static class Bootstrapper
    {
    public static IUnityContainer Initialise()
    {
      var container = BuildUnityContainer();

      DependencyResolver.SetResolver(new UnityDependencyResolver(container));

      // this throws "does not appear to implement Microsoft.Practices.ServiceLocation.IServiceLocator.... error"
      DependencyResolver.SetResolver(new IoCContainer(container)); 

      return container;
    }

    ....
  }

这是IoCContainer类

public class ScopeContainer : IDependencyScope
    {
        protected IUnityContainer container;

        public ScopeContainer(IUnityContainer container)
        {
            if (container == null)
            {
                throw new ArgumentNullException("container");
            }
            this.container = container;
        }

        public object GetService(Type serviceType)
        {
            if (container.IsRegistered(serviceType))
            {
                return container.Resolve(serviceType);
            }
            else
            {
                return null;
            } …
