asp.net - 部署时抛出 SecurityException

Question

我刚刚编写了一个 MVC 应用程序并让它在我的实验室中运行。现在我已将其部署到 GoDaddy，但收到以下错误。

Description: The application attempted to perform an operation not allowed by the security policy. To grant this application the required permission please contact your system administrator or change the application's trust level in the configuration file.

Exception Details: System.Security.SecurityException: Request failed.

Source Error: An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below.

堆栈跟踪:

我想知道我的数据库连接字符串，尽管该错误似乎并不表明数据库有任何问题。

所以我真正的问题是:如何解决这个问题。这些消息似乎根本没有帮助。下一步可能是什么？

Answer 1

这似乎是我用来构建应用程序的 .NET 版本与主机上提供的版本不匹配的问题。

感谢 Microsoft 提供的另一条错误消息，该消息似乎没有告诉我根本问题是什么。
