ioxide

A shared-nothing io_uring runtime for .NET. One reactor per core, each with its own ring, and handlers are plain async code that always resumes on its reactor.

dotnet add package ioxide

HTTP/2, HTTP/3, QUIC, the clients and the ASP.NET Core transport are separate ioxide.* packages.

• Documentation: guides and runnable examples.
• Playground: one complete server per workload, ready to copy and run.

Each reactor locks about 1 MB of memory, so raise ulimit -l if a server with many reactors won't start.
