Background Processing with .NET 10

Building a background task is easy. Building one that survives failures, shuts down cleanly, controls overload, avoids duplicate work, and keeps running reliably in production is much harder.

Background Processing with .NET 10 gives you a clear, step-by-step path from simple Worker Service fundamentals to dependable production background systems. You do not need prior experience with IHostedService, BackgroundService, Channels, durable messaging, backpressure, idempotency, or OpenTelemetry. A basic working knowledge of C# and async/await is enough.

Using one practical project-DocFlow, a document-processing Worker Service-you will build confidence one layer at a time. Each chapter introduces a problem, explains why it matters, and shows how to solve it with focused examples. Mistakes, failed shutdowns, duplicate work, slow dependencies, and growing queues become useful engineering signals that help you improve your system.

• Practical, incremental .NET 10 Worker Service development

• Real-world coverage of hosted services, scheduling, queues, concurrency, resilience, testing, observability, and deployment

• A hands-on DocFlow project that grows throughout the book

• Small, manageable code examples with clear explanations

• Verification checklists, review questions, practical exercises, troubleshooting guidance, and production-readiness references

• Build Worker Services with the .NET Generic Host

• Use IHostedService, BackgroundService, dependency injection, configuration, and logging

• Design cancellation and graceful shutdown correctly

• Run scheduled work with PeriodicTimer and TimeProvider

• Build bounded producer-consumer queues with System.Threading.Channels and backpressure

• Control concurrency, parallelism, throughput, and resource pressure

• Implement durable message processing with Azure Service Bus

• Apply retries, backoff, idempotency, deduplication, and inbox/outbox patterns

• Test cancellation, timing, queues, messaging, and failure paths

• Add structured logging, metrics, health signals, OpenTelemetry, and tracing

• Deploy workers in containers, Windows Services, and Linux systemd

C# developers, self-learners, students, and professionals who are new to background-processing architecture and want a practical route to production-ready Worker Services. No previous experience with .NET hosted services, Channels, durable messaging, or observability is required.
