Question

我将项目从.net core 2.2升级到3.1，该项目在我的visual studio 2019中运行良好，在登台服务器中出现了问题，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进程外，则可以正常工作。

所以我尝试使用默认的.net核心项目（API-.net core 3.1），并遇到了相同的问题->问题不是我的代码。我确实安装了sdk和主机捆绑软件3.1，下面是ancm日志和dotnet信息，我注意到“主机（对支持有用）” 显示“版本：2.1.4 “ ，并且Ancm显示”位于'E：\ Program Files \ dotnet \ host \ fxr \ 2.1.4 \ hostfxr.dll'的hostfxr.dll”

为什么无法根据Microsoft文档https://docs.microsoft.com/en-us/dotnet/core/distribution-packaging

加载最新版本
感谢您的任何帮助或建议。

更新：我找到了根本原因，托管捆绑软件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，因此我必须更正E驱动器上的安装，问题已解决。

Answer 1

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 json。

在连接字符串上使用无效的 \。

Answer 2

来自Microsoft Doco：

在Windows上，我们建议安装主机捆绑包，其中包括.NET Core Runtime和IIS支持。

因此，如果您是通过IIS托管的，则应该可以解决问题。

Answer 4

以防万一有人会遇到这个问题。尝试查看 appsetings.json 文件是否是正确的 json。因为如果不是所有的应用程序都会崩溃。谁愿意在这些时候使用 try/ catch？

Answer 5

还有一个可能的问题。不要忘记在 Program.cs 中运行您的资源：

IHost host = CreateHostBuilder(args).Build();
//mess up your stuff here, but don't forget:
.
.
.
host.Run();
