Use Channel<T> to coordinate producer/consumer background processing inside a .NET service while respecting backpressure and shutdown.
Explain async/await as C# syntax over Task-based asynchronous work, with attention to non-blocking I/O and request throughput.
Explain why starting background work without awaiting or tracking it is risky in ASP.NET Core applications.
Explain how a .NET BackgroundService should handle cancellation, in-flight work, and application shutdown.
