How to get a .NET Cores configuration using IIS GetWebConfiguration?

Question

I'm creating a .NET Core 2.1 Web API project (with Angular 7 front-end) where I'm using the Microsoft.Web.Administration API to pull information from remote IIS web servers (mainly listing websites, applications, app-pools, etc.):

https://learn.microsoft.com/en-us/dotnet/api/microsoft.web.administration?view=iis-dotnet

As a quick note, here is how I am instantiating a remote-IIS server object, a ServerManager object:

To create the ServerManager object (the IIS 'container' object, so-to-speak) I use one of the hidden constructors where I pass the remote IIS server's applicationHost.config file path to it (located at C:\Windows\System32\inetsrv\config -- default location). I'm doing this because I receive COM-related issues when I use the ServerManager.OpenRemote(string server_ip) method.

Anyways, whenever I'm trying to use the ServerManager's, Site's, and Application's GetWebConfiguration methods to get the Web.config files for each IIS object, each of the aforementioned object's GetWebConfig methods fail. The app doesn't crash when I run my code, but upon object inspection in the debugger, this is the following error listed:

my_siteWebConfig.RootSectionGroup = 'my_siteWebConfig.RootSectionGroup' threw an exception of type 'System.IO.DirectoryNotFoundException'

It looks like the GetWebConfiguration code is looking for the site/application's web.config file in an non-existent directory. Debugger shows that the ConfigurationPathToEdit equals "MACHINE/WEBROOT/APPHOST/my_site". It's looking in the directory where the applicationHost.Config file is (the global IIS settings file location). However, my websites' & applications' web.config files are stored under the D:\ drive at D:\MyCompany. Is there a way for the GetWebConfiguration methods to look at a directory other than the default applicationHost.Config directory for the config files?

Sorry if this is a bit confusing. Thanks for any help, and let me know if something isn't clear. Thank you.
