CS0012:类型'System.Web.Routing.RouteValueDictionary'在未引用的程序集中定义

Question

我使用新的"ASP.NET MVC 2空Web应用程序"项目得到此错误:

CS0012:类型'System.Web.Routing.RouteValueDictionary'在未引用的程序集中定义.您必须添加对程序集'System.Web.Routing,Version = 3.5.0.0,Culture = neutral,PublicKeyToken = 31bf3856ad364e35'的引用.

更新web.config文件:

<?xml version="1.0"?>
<configuration>
    <system.web>
        <compilation debug="true" targetFramework="4.0">
            <assemblies>
                <add assembly="System.Web.Abstractions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
                <add assembly="System.Web.Routing, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
                <add assembly="System.Web.Mvc, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
                <add assembly="System.Data.Entity, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"/>
            </assemblies>
        </compilation>
        ...
    </system.web>
    ...
