使用的版本：
EPiServer 10（包含最新的软件包更新）
Visual Studio 2017 15.0.0-RTW + 26228.4
VS 2015也会出现
序：
EPiServer是一个CMS，它允许在代码中定义内容类型和页面类型。更新后，任务将更新数据库中的相应项目。
当我在页面类型中添加或删除属性，并构建解决方案，并且我之前运行过该项目时，我会看到“等待操作超时”的黄色死亡屏幕。试图将片段发布在pastebin上，不允许明显地链接到那里，所以享受完整的copypaste：
Server Error in '/' Application.

偶尔我可以通过修改web.config强制网站重启来解决这个问题。有时需要重新启动4-5次，有时我会放弃并重新启动Visual Studio，因为停止并重新启动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（我把它放到引号中因为我发誓它不能一次工作）YSOD-less执行是重启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得到504，但幸运的是，它们会在一些刷新中得到解决。不确定为什么它只是死于IIS Express。
我尝试过常用的修补程序，它试图在连接字符串中使用自定义超时，以及像dataStore configsection这样的epi特定修复程序。小人物。
当然，当我们处于开发阶段时，这是一个非常令人厌烦的问题，因为属性每天都会被多次更新和删除，而且任何花费在启动上的时间都不会花在开发上。有没有办法确保无论发生什么其他错误，都不会出现与超时联系有关的问题？
