Daniel Roth frames .NET 11 as a step toward “agentic web apps”, combining faster and more secure ASP.NET Core and Blazor fundamentals with tighter integration into .NET Aspire for distributed app development, plus new building blocks (agents, tools, skills, and components) aimed at agentic experiences.

Overview

The session covers new and upcoming capabilities across Blazor, ASP.NET Core, and .NET Aspire, with demos that focus on UI components, form handling patterns, validation and localization, and Aspire-based templates and tooling.
