gRPC in .NET: Basics & More
summary
gRPC is a first-class RPC option in .NET since Core 3.0 with .NET 6 recommending it for new RPCs; the session shows actual code generation from .proto files using Grpc.AspNetCore, Grpc.Tools and protoc, demonstrates a working console client and ASP.NET Core server (including a bi‑directional streaming demo that runs), and explains four modes: unary, server streaming, client streaming and bidirectional. It stresses reuse gRPC channels for performance, shows versioning by package name so URLs become greet.v1/greeter/Method, covers hosting limits (AKS, Container Apps, App Service on Linux, gRPC‑Web for Windows/IIS), and previews gRPC JSON transcoding in .NET 7. Tools shown: Google.Protobuf, grpcurl, BloomRPC, Postman.
