推荐答案

感谢您的回答.我的托管服务 (hostgator) 似乎无法使用 MVC5.

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

当前版本的 ASP.NET 现在只支持完全信任.女士有在发行说明中说明: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.你可以阅读更多关于 ASP.NET 的官方立场Levi's 的回答是-trying-to-develop-for-medium-trust-a-lost-cause，其中还包括有关为何移除支持的进一步链接.

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.
