Learn how to build gRPC services in .NET with Protocol Buffers. Step-by-step C# tutorial with code, streaming, best practices, and pitfalls. Start now. If you have ever profiled a busy ASP.NET Core REST API, you know where the time goes: JSON serialization, HTTP/1.1 connection churn, and hand-written client code that drifts out of sync with the server. gRPC .NET fixes all three. It uses Protocol Buffers for compact binary serialization, HTTP/2 for multiplexed connections, and code generation so your client and server share a single contract. In this tutorial you will build a complete gRPC service in C#, add streaming, call it from a .NET client, and learn the best practices and pitfalls that separate a demo from a production system. What Is gRPC and Why Use It in .NET? gRPC is a high-performance Remote Procedure Call framework originally built at Google and now maintained by the Cloud Native Computing Foundation. Instead of exposing resources over URLs like REST, you define servi...
