MvcPager Ajax报错怎么办？

[qq_31206109]

MvcPager不是很懂，我用的是vs2012 ，MVC4 ASPX视图；项目添加MvcPager引用了（MvcPager版本1.5）
错误信息：

编译错误

说明: 在编译向该请求提供服务所需资源的过程中出现错误。请检查下列特定错误详细信息并适当地修改源代码。 

编译器错误消息: CS0012: 类型“System.Web.Routing.RouteValueDictionary”在未被引用的程序集中定义。必须添加对程序集“System.Web.Routing, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35”的引用。

行 69:         <%=Ajax.Pager(Model, new PagerOptions() { 

这是页面代码：

<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<PagedList<cnGameInfo>>" %>
<%@ Import Namespace="Webdiyer.WebControls.Mvc" %>
<%@ Import Namespace="WJBZ.Models" %>

        </thead>
        <tbody>
            <%using (Entities db = new Entities())
              {%>
            <% foreach (cnGameInfo item in Model)

            <tr>

                </td>
            </tr>

                                                  CurrentPagerItemWrapperFormatString = "<li class=\"paginItem current\"><a href=\"javascript:;\">{0}</a></li>",
                                                  MorePagerItemWrapperFormatString = "<li class=\"paginItem more\">{0}</li>",

                                                  PageIndexParameterName = "id",
                                                  PrevPageText = "<",
                                                  SeparatorHtml ="",
                                                  ShowFirstLast = false },
                              new AjaxOptions() { UpdateTargetId = "dvList" })%>

        <%--<%=Html.Pager(Model, new PagerOptions() { 
                                                  CssClass = "paginList",
                                                  CurrentPagerItemWrapperFormatString = "<li class=\"paginItem current\"><a href=\"javascript:;\">{0}</a></li>",
                                                  MorePagerItemWrapperFormatString = "<li class=\"paginItem more\">{0}</li>",
                                                  NavigationPagerItemWrapperFormatString = "<li class=\"paginItem\">{0}</li>",
                                                  NextPageText = ">",
                                                  NumericPagerItemCount = 5,
                                                  NumericPagerItemWrapperFormatString = "<li class=\"paginItem\">{0}</li>",
                                                  PageIndexParameterName = "id",
                                                  PrevPageText = "<",
                                                  SeparatorHtml ="",
                                                  ShowFirstLast = false })%>--%>
    </div>
</div>

但是加上下面这句话页面就会报错

<%=Ajax.Pager(Model, new PagerOptions() { 
                                                  CssClass = "paginList",
                                                  CurrentPagerItemWrapperFormatString = "<li class=\"paginItem current\"><a href=\"javascript:;\">{0}</a></li>",
                                                  MorePagerItemWrapperFormatString = "<li class=\"paginItem more\">{0}</li>",
                                                  NavigationPagerItemWrapperFormatString = "<li class=\"paginItem\">{0}</li>",
                                                  NextPageText = ">",
                                                  NumericPagerItemCount = 5,
                                                  NumericPagerItemWrapperFormatString = "<li class=\"paginItem\">{0}</li>",
                                                  PageIndexParameterName = "id",
                                                  PrevPageText = "<",
                                                  SeparatorHtml ="",
                                                  ShowFirstLast = false },
                              new AjaxOptions() { UpdateTargetId = "dvList" })%>

实在不懂，求帮忙，谢谢

解决了，在bin目录下放了一个3.5版本的System.Web.Routing.dll就好使了，
不知道为什么，直接引用这个dll会自动变成4.0.0.0版本
改个名字在引用说
错误 1 类型“System.Web.Routing.RouteCollection”同时存在于“C:\Program Files\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.6\System.Web.dll”和“C:\Users\***\Desktop\Routing.dll”中 D:\T\T\App_Start\RouteConfig.cs 12 43 T
