How can I get rid of IIS things with minimal change to my code?

[Ruikuan]

I am trying to publish my web app as self-contained single file, the result files include 'aspnetcorev2_inprocess.dll', but I have been using kestrel as edge server for a long time, didn't used IIS any more. So I want to get rid of those IIS things totally to achieve fewer files and smaller file size(link trimming).

But the UseIIS and UseIISIntegration is called by ConfigureWebHostDefaults. ConfigureWebHostDefaults is very convenient so I want to keep it. Now, how can I get rid of IIS things totally with minimal change to my code?

No, I don't want to use /p:IncludeNativeLibrariesForSelfExtract=true.
