This session covers how agentic modernization can accelerate a .NET upgrade. We'll walk through a real migration end to end, from assessing what will break before you start, through the upgrade itself, to getting a change your team will actually merge. Along the way we'll look at where the agent does the work for you, where it hands back to you, and how to extend it with your own skills when your codebase doesn't match the default path.

What if a complete native Windows app were a single C# file - no .csproj, no App.xaml, no code-behind, no ViewModels?

Microsoft.UI.Reactor is an experimental C# framework that brings the MVU (Model-View-Update) pattern to WinUI 3. Your UI is a function of your state. State lives in hooks, next to the code that uses it. And every control on screen is a real WinUI control - the same runtime, the same controls, the same theming as the XAML app next door.

We'll start by running a complete Windows app with dotnet run app.cs, then build up: hooks and state, lists and keyed reconciliation, and the 60+ Roslyn analyzers that catch UI bugs while you type - because when your UI is ordinary C#, the entire .NET toolchain points straight at it.

This is an experiment, and the talk is honest about that: what works, what's rough, what we got wrong, and where XAML and MVVM fit alongside it (spoiler: they aren't going anywhere). Come for the live demo, leave with an opinion - we're actively collecting them.

Microsoft Foundry keeps raising the bar for AI. What does that mean for your next C# app? Join this session for a demo-packed tour of the latest Foundry features and services, and discover how to get the most out of them with .NET. From powerful models to new AI capabilities, we’ll explore what’s new, what matters, and what’s worth bringing into your projects. Less slideware, more possibilities, and plenty of “I could use that!” moments.

AI can generate your XAML and C#, but can it tell whether the button is actually visible or the screen behaves as intended? Building mobile and desktop apps takes more than code generation. Your AI assistant needs eyes and hands on the running app.

In this demo-driven session, we'll explore how DevFlow and an interactive mobile canvas connect GitHub Copilot to a running .NET MAUI app. Starting with an existing application, we'll inspect the UI, give the assistant context about specific controls, interact with the app, and use logs and runtime information to investigate problems. We'll then make targeted code changes and replay user workflows to check the results.

Along the way, we'll see where MCP fits, what these experimental tools can and cannot do, and where developer judgment still matters. You'll leave with practical patterns for moving beyond generated code to an AI-assisted feedback loop for your own .NET MAUI apps.

C# file-based apps are getting a serious upgrade in .NET 11.

In this session, we’ll tour the latest improvements, including faster launch performance, app-to-app references, richer package reference support, and expanded CLI support across more `dotnet` commands. We’ll see how file-based apps are growing from a lightweight way to run a single C# file into a surprisingly capable model for building real tools and applications—without giving up the simplicity that made them compelling in the first place.

If you’ve been curious how far C# can go without a project file, .NET 11 turns it up to 11!
