等待操作超时

Question

我对MVC代码的第一个应用程序开发相对较新，我试图在VPS中托管MVC代码第一个应用程序。当试图在发布应用程序后浏览网站时，我得到了一个等待操作超时错误。我试图做一些研究，发现启用SQL上的TCP/IP 配置管理员帮助了一些，但我没有运气。以下是堆栈跟踪，任何人都知道最新的问题？

Answer 1

我认为这可能对未来寻找同样错误的答案有用。

感谢大家的帮助，但是我面对的问题是因为我忘记将用户添加到我的应用程序池中！愚蠢的错误从我身边！

Answer 2

我有同样的问题。某些SQL升级命令运行时间非常长，并且由于默认超时设置为30秒而导致错误。我发现以下文章SO来克服这个问题： EF Code First - Timeout expired. The timeout period elapsed prior to completion

对我来说，它的工作原理是在Configuration.cs文件中将CommandTimeout设置为180秒。

祝你好运
