Answer 1

In dotnet standard/core:

Import the NuGet package as user bvpb mentioned. System.IO.FileSystem.AccessControl

Then instead of this (which only works in .NET Framework):

FileSecurity fSecurity = File.GetAccessControl(fileName);

use this (which works in all versions of .NET):

FileSecurity fSecurity = new FileSecurity(fileName, AccessControlSections.Owner | 
                AccessControlSections.Group |
                AccessControlSections.Access);

You may need AccessControllSections.All instead which requires the account running this code to have more permissions.
