无法将"ASP._Page__ViewStart_cshtml"类型的对象强制转换为"System.Web.WebPages.StartPage"类型

Question

我正在为学校做一个项目.当我尝试将站点地图添加到我的网站时,会出现该错误.

堆栈跟踪:

[InvalidCastException: Unable to cast object of type 'ASP._Page__ViewStart_cshtml' to type 'System.Web.WebPages.StartPage'.]

我试图撤消更改,并重建项目,但我仍然得到此错误.我在最后一次构建时有一个备份,当我解开时的代码和来自备份的代码是相同的,但备份代码不会给我错误.这是一个错误吗？
(我的英语不好,对不起)

我不知道,如果这对你有所帮助,但当我将_ViewStart.cshtml从Views文件夹移到我项目的根文件夹时,我偶然发现了同样的问题.也许你偶然做了同样的事情？
