Hosted Services require keep alive
转自: https://stackoverflow.com/questions/53753802/do-recurring-hosted-services-require-keep-alive
If you run your ASP.NET Core application in IIS (not IIS Express):
- For your hosted service to start automatically, you need to set the Start Mode of the application pool to Always Running. See Rick Strahl for more information.
- For your hosted service to keep running indefinitely, you need to set the Idle Time-out of the application pool to 0.
If you run the application as a Windows Service, none of this is needed.
Also, for forward compatibility, make your hosted service inherit the BackgroundService
class and register it for dependency injection using AddHostedService
.
AFAIK, using the IIS in-process hosting model in .NET Core 2.2 has no effect on this.
