How do you manage DI in Background Services / Hosted Services?

Background services run independently of user requests and usually operate as Singletons. This creates friction when they need Scoped dependencies.

To use a database (Scoped) inside a background worker (Singleton), the worker must explicitly create a new dependency scope using a Scope Factory. It resolves the Scoped services, performs the work, and ensures the scope is disposed properly to release the resources.
