asp.net-mvc-5 - Mvc 5.1 MissingMethodException System.Web.WebPages.TypeHelper.ObjectToDictionaryUncached

Question

我将 MVC5 项目更新为 MVC5.1，现在路由字典出现异常:

routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

堆栈跟踪:

{"Method not found: 'System.Web.Routing.RouteValueDictionary System.Web.WebPages.TypeHelper.ObjectToDictionaryUncached(System.Object)'."}

在引用文献中，我发现System.Web.WebPages.dll版本3.0.11001.0显示这种类型的错误，但是当我将其替换为System时.Web.WebPages.dll版本3.0.20129.0它可以工作。因此，您只需从引用中删除旧版本并下载其他版本，然后干净的解决方案，重建，它就会起作用。
