.NET 11: What's New in Blazor (30+ Features)

Описание: The demands on modern web apps keep rising – performance, security, observability, and now agentic capabilities. In this session, Daniel Roth (Principal PM for ASP.NET Core & Blazor) walks through what's coming in .NET 11 for web development, with live demos on .NET 11.

From a stronger foundation (Kestrel perf, native OpenTelemetry, DBSC) to a filled-out Blazor static SSR story, distributed apps with Aspire, and building agentic UIs with AG-UI – this is a full tour of the .NET 11 web stack.
