Preview 6 of Microsoft’s .NET 11 software development platform is now available, with improvements across the runtime, libraries, frameworks, and C# and F# programming languages.
Announced July 14, .NET 11 Preview 6 can be downloaded from dotnet.microsoft.com. The full, general production release is expected in November. The first preview was unveiled February 10.
Runtime-async, the .NET runtime’s built-in implementation of async/await, keeps getting faster in Preview 6, building on the suspension improvements from Preview 5. Async continuations can now opt out of ExecutionContext capture and restore. And the JIT now compiles a dedicated runtime-async version of a synchronous, task-returning method rather than delegating to it through a thunk. The JIT turns the method’s tail calls into runtime-async calls and awaits the task that would otherwise have been returned, so the async path no longer pays for an extra layer of indirection, Microsoft said.
