.NET gRPC - Deep Dive
summary
Explains how .NET implements gRPC end to end: proto3 files generate C# types, Grpc.Net.Client + Google.Protobuf + Grpc.Net.ClientFactory make clients, and services run on HTTP/2 with binary protobuf payloads for unary, server, client and bidirectional streaming. Demos show a server and four console clients working (streams travel over a single TCP connection), JSON transcoding via Grpc.AspNetCore.GrpcJsonTranscoding exposes browser-friendly endpoints, retries and hedging/retry policies execute as configured, and client-side load balancing (static resolver + round robin) actually routes to multiple instances; all calls are POST so URL caching isn’t available.
