Build high-performance APIs with gRPC and .NET
summary
Shows how to build a gRPC service and client on .NET 5 using Grpc.AspNetCore and Grpc.Net.Client with ProtoBuf code generation, Visual Studio Add Connected Service, and an actual Greeter demo that runs: a unary call and a server streaming demo of 10 messages with 1s delays, both working end-to-end. Reports 92% allocation reduction in .NET 5, server throughput up ~60% and client RPS +230% versus .NET Core 3. Covers gRPC-Web, Kestrel/IIS hosting, keepalive pings, and IPC via domain sockets/named pipes.
