Mvc 5.1 MissingMethodException System.Web.WebPages.TypeHelper.ObjectToDictionaryUncached

Question

我将我的MVC5项目更新为MVC5.1,现在在路由字典上有异常:

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

堆栈跟踪:

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

在References中我发现System.Web.WebPages.dll版本3.0.11001.0显示了这种类型的错误,但当我用System.Web.WebPages.dll版本3.0.20129.0替换它时它可以工作.因此,您应该从refrences中删除旧版本并下载其他版本,而不是干净的解决方案,重建并且它将起作用.
