Pull request overview
This PR updates the XML documentation for the AddHostedService extension methods to clarify that these methods only register the service as IHostedService in the DI container, not as the concrete type itself. This addresses confusion reported in issue #53831 where developers expected the concrete type to also be registered.
Changes:
- Added
<remarks>sections to both overloads ofAddHostedServiceexplaining the registration behavior - Included code examples demonstrating the workaround pattern for registering both the concrete type and the hosted service
