Embracing gRPC in .NET
summary
Shows concrete .NET setup: a gRPC server (dotnet project template) and four console clients exercising unary, server streaming, client streaming, bidirectional. Uses protobuf binary over HTTP/2, auto-generates C# clients and base classes, exposes headers/trailers, RPC-specific status codes and RPCException handling, and adds Interceptors, compression and deadlines. Demonstrates proto-driven contract, shows payloads around 80% smaller than JSON in the demo, enables grpc transcoding to expose HTTP endpoints, and attempts client-side load balancing (round‑robin) though that demo fails live while the other demos work.
