The .NET 11 runtime introduces significant changes to its async/await implementation, moving beyond the traditional state machine approach. This analysis explores how the runtime leverages Continuation Passing Style (CPS) to manage asynchronous operations more efficiently. Key improvements include reduced memory allocations, faster context switching, and better support for high-throughput scenarios. The post breaks down the internal data flow, showing how continuations are scheduled and executed. For developers building scalable services, understanding these runtime changes is crucial for optimizing performance. The article also discusses potential pitfalls and migration considerations for existing codebases. Overall, .NET 11's async runtime represents a major step forward in asynchronous programming efficiency.
