Announcing .NET 11
Today, we're excited to announce the release of .NET 11!
This year's release makes building modern applications faster, more productive, and has improvements across C# 15, ASP.NET Core, .NET MAUI, and Windows development. With hundreds of runtime optimizations, more responsive SDK tooling, and less overhead in everyday commands, you can spend less time waiting and more time creating. Build richer web and cross-platform applications, take advantage of new C# language features, and explore AI-powered development with improved tools and agentic capabilities.
