IIS part of microsoft/dot net-framework:4.6.2

Expected behavior

IIS part of microsoft/dot net-framework:4.6.2?


I am using docker file with FROM microsoft/dotnet-framework:4.6.2.
I am able to run web application after using dot net framework.

Is IIS web server part of dotnet framework?
I have checked C:\Programdata…\Inetsrv\ folder and it is empty.

How application running without IIS installation on the server?

Please explain in detail.
