An error occurred while starting the application.

. NET Core X64 v4.1.1.0 | Microsoft. AspNetCore. Hosting version 1.1.0-rtm-22752 | Microsoft Windows 6.3.9600

This error is reported, and the Environment is correctly configured according to the official documentation. What should I do?

1. Modify the web. config file and change stdoutLogEnabled to true, as shown below:

<aspNetCore processPath="dotnet" arguments=".\Dialysis.WebApi.dll" stdoutLogEnabled="true" stdoutLogFile=".\logs\stdout" />

2. Open the website again and report the above error. Don't worry. Check the root directory of the release and find that there is an additional Logs folder to open the stdout_xxx.log file.
