如果出现以下问题，一般从表面是无法找到错误根源。

HTTP Error 502.5 - ANCM Out-Of-Process Startup Failure

Common solutions to this issue:

The application process failed to start
The application process started but then stopped
The application process started but failed to listen on the configured port

Troubleshooting steps:

Check the system event log for error messages
Enable logging the application process' stdout messages
Attach a debugger to the application process and inspect

解决方案：

1、先打开站点下面的web.config文件

<?xml version="1.0" encoding="utf-8"?>
<configuration>
<location path="." inheritInChildApplications="false">
<system.webServer>
<handlers>
<add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModuleV2" resourceType="Unspecified" />
</handlers>
<aspNetCore processPath=".\WebApi.exe" stdoutLogEnabled="false" stdoutLogFile=".\logs\stdout" hostingModel="OutOfProcess" />
</system.webServer>
</location>
</configuration>

修改

stdoutLogEnabled="false" 值设置为“true”

<?xml version="1.0" encoding="utf-8"?>
<configuration>
<location path="." inheritInChildApplications="false">
<system.webServer>
<handlers>
<add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModuleV2" resourceType="Unspecified" />
</handlers>
<aspNetCore processPath=".\WebApi.exe" stdoutLogEnabled="true" stdoutLogFile=".\logs\stdout" hostingModel="OutOfProcess" />
</system.webServer>
</location>
</configuration>

这样修改的目的就是为了生成错误日志方便我分析

HTTP Error 502.5

是什么原因引起的。

下面就是我遇到的错误原因：

Unhandled exception. System.Exception: Repository.dll和service.dll 丢失，因为项目解耦了，所以需要先F6编译，再F5运行，请检查 bin 文件夹，并拷贝。
at Begon.Extensions.ServiceExtensions.AutofacModuleRegister.Load(ContainerBuilder builder) in I:\柏港网站集\柏港统一订单平台\BlazorApp\Begon.Extensions\ServiceExtensions\AutofacModuleRegister.cs:line 34

产生的原因就是在发布项目是原本解耦了的dll文件没有被一起发布，所以差文件DLL。

所以网上查到的一些解决方法根本无法解决自己的问题，这就说明了产生

HTTP Error 502.5

并不一定是。。。所以要看错误日志分析来解决。
