.NET 11 has reached its Release Candidate 1 (RC1) status, signaling the next iteration of the .NET platform is nearing its November 2026 release. Microsoft made .NET 11 RC1 available on September 8, 2026, with Go-Live support for production use. This release encompasses enhancements to the runtime, SDK, libraries, MSBuild, NuGet, C#, F#, ASP.NET Core, .NET MAUI, and Windows Forms.
The significance of .NET 11 lies in its focus on deeper platform-level improvements, extending beyond a mere version update. For instance, runtime and performance optimizations, such as NativeAOT, asynchronous execution, and CoreCLR, are undergoing continuous refinement. Additionally, the integration of C# 15 brings new language features, like union types, which can enhance the expressiveness of domain models and API contracts for developers crafting large applications.
ASP.NET Core and Blazor also undergo substantial updates in the .NET 11 cycle, with a shift towards richer server-side rendering, improved validation, and streamlined Blazor WebAssembly applications. These advancements aim to provide a smoother development experience for modern .NET applications.
.NET MAUI developers are particularly encouraged to take note of the upcoming changes in .NET 11. A key development is the shift towards CoreCLR for .NET MAUI applications on Android, iOS, and Mac Catalyst. This evolution could prove beneficial for developers creating production cross-platform applications using MAUI.
Before adopting .NET 11, it is advisable for teams to conduct thorough testing of their applications, dependencies, workloads, and CI/CD pipelines. While .NET 11 RC1 is now Go-Live, signifying Microsoft's support for its production use, teams currently on .NET 10 do not need to rush, as .NET 10 remains supported until November 14, 2028, while .NET 11 is an STS release.
The official launch of .NET 11 is anticipated in November 2026, coinciding with the .NET Conf 2026 event. For .NET developers, testing .NET 11 in non-production projects and assessing how applications behave with the new runtime can be advantageous as .NET 11 draws closer.
