An application developed using .NET Core and integrated with Quartz.net is hosted on an IIS server.
The following configurations have been set on the IIS server:
- Application Pool --> Advanced settings: Start Mode: Always Running
- Application Pool --> Idle Time-out (minutes): 0
- Default Web Site --> Hosted Application --> Preload Enabled: True
The issue encountered is that after an automatic IIS recycle (1740 minutes), the application does not start automatically, resulting in the Quartz.net timer not running.
Environment details:
- .NET Core 8.0
- Windows Server 2019/2022
- IIS 10
