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>
<!--ProjectGuid: 2db5a0c4-8146-4ec6-981b-cb5df2052cee-->

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>
<!--ProjectGuid: 2db5a0c4-8146-4ec6-981b-cb5df2052cee-->
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

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。

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
