Here's the meaty part, in case the link dies:

To host an ASP.NET Core app as a sub-app under another ASP.NET Core app:

1.Establish an app pool for the sub-app. Set the .NET CLR Version to No Managed Code because the Core Common Language Runtime (CoreCLR) for .NET Core is booted to host the app in the worker process, not the desktop CLR (.NET CLR).

2.Add the root site in IIS Manager with the sub-app in a folder under the root site.

3.Right-click the sub-app folder in IIS Manager and select Convert to Application.

4.In the Add Application dialog, use the Select button for the Application Pool to assign the app pool that you created for the sub-app. Select OK.

As a bonus, my main application is legacy Web Forms and my sub-application is exciting new .NET Core functionality.

Happy days.
