我有一个 razor 2.0 表单，可以在本地完美运行。我已经验证了用于 MVC、Razor 和 helpers 的 dll 都是最新版本。我在每个使用@Html.BeginForm不同参数的页面上都遇到了这个异常。只要不使用表单助手，MVC 页面似乎就可以正常工作：

这种形式非常简单：

我最初怀疑 dll 的版本错误或缺失。所有 MVC 组件都应该在 bin 文件夹中，并且我已经验证了这一点（至少是顶级 dll）

This project uses a combination of ASP pages and MVC Views, and previously was working with webforms 1.0 and MVC 2.0. The application is setup as an application under the default website. I've seen lots of variations with this same exception but most came down to syntax errors in the form helpers. This seems to be more environmentally related. Any help would be greatly appreciated!
