推荐答案

感谢您的回答.看来我无法在托管服务(hostgator)中使用MVC5.

Thanks for your answers. It looks like I cannot use MVC5 with my hosting service (hostgator).

当前版本的ASP.NET现在仅支持完全信任. MS有 发行说明:已知问题中所述，"ASP.NET MVC 5不再 支持部分信任...".特别是[程序集: [AllowPartiallyTrustedCallers]属性已从 源代码.您可以在下面阅读有关ASP.NET官方职位的更多信息. 李维斯(Levi)的答案是尝试开发一种中等的信任，因为它已经失去了原因， 其中还包括有关为何删除支持的更多链接.

The current versions of ASP.NET now only support full trust. MS have stated in Release Notes: Known Issues that "ASP.NET MVC 5 no longer supports partial trust....". In particular the [assembly: AllowPartiallyTrustedCallers] attribute has been removed from the source code. You can read more about ASP.NET's official position in Levi's answer to is-trying-to-develop-for-medium-trust-a-lost-cause, which also includes further links to why support has been removed.
