Key Concepts:
- IHost: Initializes and configures services for the application.
- IHostedService: Represents background services with lifecycle management.
- Graceful Shutdown: Handling cleanup tasks when the application stops.
In .NET Core, the IHost interface is used to configure and run applications, particularly when implementing background services or hosting long-running processes. By using IHostedService, developers can easily manage these services with built-in support for dependency injection, logging, and graceful shutdown.
