部署时抛出SecurityException [英] SecurityException thrown on deployment

问题描述

我刚刚编写了一个MVC应用程序，并使其在实验室中可以正常工作。现在，将其部署到GoDaddy上，出现以下错误。

I have just written an MVC application and got it working in my lab. Now that I've deployed it to GoDaddy, I am getting the following error.

我想知道我的数据库连接字符串，尽管错误似乎没有建议数据库有任何问题。

I wondered about my database connection string, although the error doesn't seem to suggest any issue with the database.

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

So my real question is: How does one go about troubleshooting this. The messages don't really seem to help at all. What could be a next step?

推荐答案

这似乎是我所使用的.NET版本之间不匹配的问题

This appears to be an issue with a mismatch between the version of .NET I'm using to build my app and the one provided on the host.

感谢Microsoft提供的另一条错误消息，该错误消息似乎对根本问题一无所知。

Thank you Microsoft for another error message that seems to tell me nothing about what the underlying issue is.
