在asp.core中托管IIS2.0WebAPI时出错

Question

我已经开发了IISCore2.0WebAPI并在asp.net中托管。我安装了Hosting Bundle Installation中提到的主机捆绑包

但是由于某些原因，我得到了以下错误：

An error occurred while starting the application.

.NET Core 4.6.25815.02 X64 v4.0.0.0    |   Microsoft.AspNetCore.Hosting version 2.0.0-rtm-26452    |    Microsoft Windows 6.1.7601 S 

stdout中的一些错误行...
