In short

Unveiled alongside the .NET Conf 2026 event, the release establishes C# 15 as the default language and transitions .NET MAUI to the CoreCLR runtime. Workflow efficiency is improved via a Native AOT CLI host and a warm MSBuild server that reduce development overhead. Web and intelligence workloads also expand through asynchronous validation, built-in Zstandard compression, and new experimental Blazor AI components.

.NET 11 support

.NET 11 is a Standard Term Support (STS) release with two years of support under the .NET support policy. STS and Long Term Support (LTS) releases have the same quality and servicing policies; the difference is the length of support. .NET 10 remains a supported LTS option.
