You speak in the past tense, but .NET 11 is not released yet at time of writing. Runtime-async is not the current reality.

True, it's in preview currently, but actually .NET is already very efficient with async today also - https://hez2010.github.io/async-runtimes-benchmarks-2024/ (.NET9 tested here).

Sure, it’s really fine for what it does, but it is not significantly easier to deal with than Rust async, and remains fundamentally unsuited in several scenarios where Rust async works really well.
