How to Gracefully Shut Down ASP.Net (not Core)

I have a WCF service application hosted in IIS. On startup, it reads the SQL connection information from the web.config and connects to the SQL Server to get the necessary information to bootstrap the application. If the SQL Server is unavailable for some reason, we want the service to shutdown - which I currently accomplish by throwing an exception.

The problem we have with this is that, if a service fails to start more than N times, IIS helpfully turns off the application pool - which means that, after the SQL Server connection issue is corrected (possibly entirely external to the IIS server), a sysadmin has to think to go an turn the app pool back on.

What I'd like to do is have the service gracefully exit. I know that there are ways to do this with ASP.Net Core (i.e., ways to hook into the lifecycle management of the process and tell it to exit), but have been unable to find anything like that for .Net Framework/ASP.Net.

Is there such an API that I can use?

Turns out that this method is available and works.
