The below script was designed to install IIS with .Net Core Runtime 2.1.x to be used with NOPCommerce. It also enables WinRM (remote management) and changes network settings on the target machine. This is used with Win Server 2019 core to automate deployments with Ansible into AWS.

#
#    The following script changes the Network settings of the Machine
#    disables the firewall, installs IIS and Core Runtime 
#
#Change PS Execution Policy
Set-ExecutionPolicy Bypass -Scope Process -Force

#Enable TLS for Invoke-Webrequest
$AllProtocols = [System.Net.SecurityProtocolType]'Ssl3,Tls,Tls11,Tls12'
