asp.net - 无法将 'ASP._Page__ViewStart_cshtml' 类型的对象转换为 '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站点时出现该错误。

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，但我仍然收到此错误。我在上次构建时有一个备份，我撤消时的代码和备份的代码是相同的，但是备份代码没有给我错误。这是一个错误吗？
(我的英文不好，抱歉)

我不知道这是否对您有帮助，但是当我将 _ViewStart.cshtml 从 Views 文件夹移到项目的根文件夹时，我偶然发现了同样的问题。也许你也做过同样的事情？
