.Net Core, Web App Executes Console App

I have a .net 2 Core web app on windows IIS. No issues with the web app. How can I successfully run: 1) a .net core console app; and 2) a regular windows executable?

The console app is needed because of the work passed to it can take several minutes - sometimes up to 10 minutes to complete. Probably too long to expect a user to keep their browser open.

I have tried using "System.Diagnostics.Process" on the windows app with much success. I figured before I started trying with the Core app, I would get some suggestions. Let me know if any additional information is needed. Thanks in advance for any suggestions.
