.NET 11 Preview 1 has been released, introducing various enhancements to the runtime, SDK, libraries, and languages aimed at improving performance and adding useful features. Notable library updates include Zstandard compression, BFloat16 support, and improved handling of Unicode graphemes, while runtime changes focus on reducing async overhead and supporting new architectures like RISC-V. The SDK has been updated with new features such as interactive framework selection and configurable hot-reload ports, making development easier. Language improvements for C# and F# include collection expression arguments and default parallel compilation, respectively, which enhance the coding experience and efficiency
.NET 11 Preview 1 released
.NET 11 Preview 1 has arrived, bringing a bundle of runtime, SDK, library, and language tweaks that aim to squeeze out performance and add missing conveniences. The libraries now ship Zstandard compression, BFloat16 support, Rune handling across string APIs, FrozenDictionary literals, and native hard‑link creation. On the runtime side Microsoft reduced async overhead, enabled CoreCLR on WebAssembly, tightened GC limits for 32‑bit processes, and added RISC‑V and s390x architecture support. The SDK gains interactive framework selection, positional test arguments, configurable hot‑reload ports, new analyzers, while C# adds collection expression arguments and F# enables parallel compilation by default.
