NET Core 3.1-HTTP错误500.30-ANCM进程内启动失败

Question

我将我的项目从.NET core 2.2升级到3.1，该项目在visual studio 2019中运行良好，问题发生在临时服务器上，它提示错误“HTTP错误500.30-ANCM进程内启动失败”。如果我将托管模型更改为outofprocess，它就可以正常工作。

如有任何帮助或建议，我们将不胜感激，谢谢。

更新：我已经找到了根本原因，主机包3.1安装在C驱动器上，而2.1.4安装在E驱动器上。系统一直指向E驱动器，所以我不得不在E驱动器上修正安装，问题就解决了。

Answer 1

在我的例子中，是因为我的appsetting.json有一个json对配置无效，我得到了这个错误。检查应用程序中使用的jsons。

连接字符串上的\无效。
