asp.net-core - 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，该项目在我的 Visual Studio 2019 中运行良好，临时服务器出现问题，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进程外，它工作正常。

所以我尝试了一个默认的 .net 核心项目(API - .net core 3.1)并遇到了同样的问题 -> 问题不是我的代码。我确实安装了 sdk 和托管包 3.1，下面是 ancm 日志和 dotnet 信息，我注意到 “主机(用于支持)”正在显示 “版本:2.1.4”并且 ancm 显示 "hostfxr.dll 位于'E:\Program Files\dotnet\host\fxr\2.1.4\hostfxr.dll'"

为什么它无法加载以下 Microsoft 文档的最新版本:https://docs.microsoft.com/en-us/dotnet/core/distribution-packaging

任何帮助或建议将不胜感激，谢谢。

更新:我找到了根本原因，托管包 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盘，所以我必须纠正在E盘上的安装，问题解决了。

就我而言，是因为我的 appsetting.json 有一个对配置无效的 json，我收到了那个错误。检查您在应用程序中使用的 jsons。
在连接字符串上使用无效的\。
