.Net Core Web应用发布至IIS后报“An error occurred while starting the application”错误
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
报这个错，一脸懵逼，环境都按官方文档配置正确了，怎么办？
1.修改web.config文件，stdoutLogEnabled改为true，如下：
<aspNetCore processPath="dotnet" arguments=".\Dialysis.WebApi.dll" stdoutLogEnabled="true" stdoutLogFile=".\logs\stdout" />
2.再次打开网站，还是报上述错误，别急，查看发布根目录发现多了一个Logs文件夹，打开里面的stdout_xxx.log文件

发现缺少文件，把文件复制到发布根目录下就解决了
