About this tag
.NET 11 is the upcoming release of Microsoft's cross-platform developer platform, and this tag collects WindowsForum coverage of its preview builds and early tooling. The tagged content centers on .NET 11 RC1, where Microsoft published experimental Blazor components for building chatbots and agent-driven interfaces under the "Agentic UI" label. The Microsoft.AspNetCore.Components.AI package lets an AI agent stream output, call tools, request permission, propose edits, and update shared data, with the Blazor app rendering that activity as inspectable interface elements. Coverage also notes that the library is unfinished and that developers testing RC1 have run into a NuGet restore issue.
