EPiServer：等待操作超时

Question

使用的版本：

EPiServer 10（带有最新软件包更新）

Visual Studio 2017 15.0.0-RTW+26228.4

VS 2015 也会发生

前言：

EPiServer 是一个允许在代码中定义内容类型和页面类型的 CMS。当这些被更新时，任务将更新数据库中的各个项目。

当我在页面类型中添加或删除属性并构建解决方案时，并且我之前已经运行过该项目，我得到一个黄屏死机，并显示“等待操作超时”。试图在 pastebin 上发布 sn-p，显然不允许在那里链接，所以享受完整的复制粘贴：

Server Error in '/' Application.

The wait operation timed out

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

有时我可以通过修改 web.config 强制重新启动网站来摆脱这种情况。有时需要重新启动 4-5 次，有时我放弃并重新启动 Visual Studio，因为停止和重新启动 IIS 不起作用，清理、重建和重新运行也不起作用。 “保证”的唯一方法（我把它放在引号中，因为我发誓它没有一次工作） YSOD-less 执行是重新启动 VS。

这也是DXC环境中可能存在的问题，因为我在部署时偶尔会遇到504，但幸运的是它们在几次刷新后得到了解决。不知道为什么它会在 IIS Express 上死掉。

我已经尝试了通常的修复，即尝试在连接字符串中使用自定义超时，以及特定于 epi 的修复，例如 dataStore configsection。齐尔奇。

当然，由于我们正处于开发过程中，这是一个非常令人讨厌的问题，因为属性每天会更新和删除多次，并且任何用于启动的时间都不是用于开发的时间。有什么方法可以确保无论发生什么其他错误，都不会出现与超时连接相关的问题？

我发现this support article 在计划作业期间出现超时异常。

在添加/删除属性时，同样的“修复”也适用于超时问题！
