gRPC with ASP.NET Core 10

gRPC with ASP.NET Core 10

Want to build fast, reliable distributed services with .NET but feel intimidated by gRPC, Protocol Buffers, streaming, HTTP/2, and microservices?

gRPC with ASP.NET Core 10 gives you a clear, practical path from your first service contract to secure, observable, production-ready distributed applications.

You do not need previous experience with gRPC, Protocol Buffers, streaming RPCs, service discovery, or distributed tracing. Basic familiarity with C# and backend development is enough. Every major implementation is broken into small, connected steps so you can understand what you are building, why it matters, and how to verify that it works.

Throughout the book, you will build FleetOps, a realistic fleet operations and telemetry platform. Instead of disconnected examples, each chapter extends the same project with new capabilities. Mistakes, failed calls, broken streams, and configuration problems are treated as part of the learning process-helping you develop practical troubleshooting skills and confidence as you progress.

• Step-by-step learning with ASP.NET Core 10, C#, gRPC, and Protocol Buffers

• Hands-on coverage of unary, server-streaming, client-streaming, and bidirectional RPCs

• Practical guidance on security, resilience, observability, testing, and performance

• Real-world use of deadlines, cancellation, retries, service discovery, and load balancing

• Deployment coverage for containers, TLS, proxies, Kubernetes, and rolling upgrades

• Verification checklists, review questions, practical exercises, and troubleshooting references

• Design version-safe Protocol Buffer contracts

• Build strongly typed gRPC services and clients

• Implement all four gRPC communication patterns

• Handle validation, status codes, errors, deadlines, and cancellation

• Secure services with TLS, authentication, and authorization

• Use metadata and interceptors for cross-cutting concerns

• Apply retries, backoff, idempotency, and duplicate-call protection

• Add health checks, service discovery, and load balancing

• Test and observe distributed systems with logging, metrics, and tracing

• Benchmark latency, throughput, memory use, and streaming performance

• Deploy and operate production-ready gRPC services

This book is ideal for developers who are new to gRPC, C# and .NET programmers moving into distributed systems, students and self-learners exploring cloud-native development, and backend developers who want practical experience building reliable service-to-service communication.
