Microsoft Announces Release of .NET 11
.NET 11 introduces faster SDK tooling, runtime optimizations, and language enhancements to help developers build modern applications more efficiently.
Microsoft has announced the availability of .NET 11. The cross-platform development platform introduces updates across its runtime, SDK, libraries, C# 15, ASP.NET Core, and .NET MAUI.
This release includes a Native AOT command-line host and an MSBuild server that stays warm between commands, reducing repeated startup work. Runtime optimizations improve generated code, while C# 15 introduces union types and closed hierarchies to help developers model application states with compiler-checked patterns.
Additional highlights include asynchronous validation and OpenAPI 3.2 in ASP.NET Core, built-in Zstandard compression, and CoreCLR as the default runtime for .NET MAUI. .NET 11 is a Standard Term Support release with two years of support. Developers can get started with Visual Studio 2026 or Visual Studio Code with the C# Dev Kit.
