To implement a .NET BackgroundService, derive from the base class and override ExecuteAsync with cancellation support, using a periodic timer or loop that respects the CancellationToken for safe background processing.

The best way to resolve scoped dependencies like DbContext in a .NET worker service is using scoped dependency patterns, creating a scope per unit of work to safely resolve services without captive dependency lifetime issues.

Handle graceful shutdown in .NET worker services by implementing windowed shutdown patterns and proper lifecycle management, ensuring cancellation tokens propagate correctly to stop long-running tasks safely during hosting termination.

Yes, you can add health checks and readiness probes to a .NET background worker by configuring health checks for liveness and readiness, enabling observability for resilient production workloads and monitoring.

Available execution patterns for .NET worker services include event-driven, queue-based, and timer-based execution, with guidance on anti-patterns to avoid when building long-running background services and hosted workers.

A .NET background service hangs during application shutdown when ExecuteAsync blocks without checking the CancellationToken, preventing graceful shutdown; implementing cancellation-safe loops and windowed shutdown patterns resolves this issue.
