Microsoft has announced the seventh preview release of the .NET 11 open source developer platform, with improvements ranging from tiered compilation for async methods and a milestone in bringing CoreCLR to WebAssembly . Developers can download Preview 7 from dotnet.microsoft.com . Production availability for .NET 11 is expected in November. Unveiled August 11 , .NET 11 Preview 7 includes improvements across libraries, the .NET runtime, SDK, C# , ASP.NET Core, .NET MAUI, Entity Framework Core, F#, and Windows Forms, according to Microsoft. With this latest preview, runtime-async — the runtime’s built-in implementation of async / await — continues to close the gap with the compiler-generated state-machine model, according to Microsoft. Async versions of methods are now compiled through the tiered compilation pipeline. Async methods previously bypassed tiering and always ran the tier0 code, which was optimized for compilation speed rather than steady-state throughput. On the WebAssembly front, .NET 11 is bringing CoreCLR to WebAssembly with a portable interpreter-plus-R2R (ReadyToRun) model that reuses RyuJIT for ahead-of-time code generation. This configuration could start up in Preview 6, and now runs the CoreCLR libraries test suite end-to-end in Preview 7. Preview 7 also brings C# language and compiler updates including labeled break and continue . With C# 15, break and continue can name an enclosing loop or switch , allowing developers to exit or continue an outer construc…
