how to make background service run in iis even if iis is idle

i am implementing a background service , the problem is when i run it in local it is working fine since the app is hit and running . but in iis i deployed code and started the server in iis. the background service is not running until i browse the site and becoming idle when the server is idle

My program. cs builder.Services.AddHostedService();

i have registered it also

the main problem is i cant create a windows service or a console app since i it is not approved in my org.

IIS typically does not start background services on its own, it relies on requests that trigger application startup. Currently, you can configure IIS to always run the site, but this is not a good workaround.

To keep a background service running, you may want to look for alternatives; after all, IIS is designed for hosting Web applications, not long-running background services.

You mentioned that your organization doesn't approve the creation of Windows services, but you may want to discuss this with your IT department. Hosting an application as a Windows service is the most common way to run a long-lived background process on a Windows computer.
