.NET gRPC - deep dive
summary
Live demo of .NET gRPC builds a Visual Studio template service and simple console clients that exercise all four RPC modes including server streaming and bidirectional streaming, using generated Protocol Buffers types. Shows Postman and a reflection-based client, implements deadlines, metadata/trailers, interceptors, and throws RPCException for validation. Configures client-side load balancing with multiple server instances, and retry/hedging policies. Adds grpc-json transcoding so browser GET/POST maps to gRPC. Claims up to ~80% smaller payloads vs JSON; demos run successfully end-to-end.
