C# Networking Deep Dive With io_uring part 2 - Bridge the Async Model

In part 1 we built the minimal io_uring loop: setup, mmaps, SQE/CQE draining, accept/recv/send via opcode dispatch.This was the first step to understanding how the kernel interface works but the dispatch logic was basically hand coded, a state machine that would not scale. This second part is all about introducing the asynchronous model to await data pushed by the kernel. For simplicity, in this article scope we will simply return the number of bytes received, in later parts it will be described
