Event Highlights

  • Day 1: Focused on .NET 10’s new features—performance upgrades, C# 14, ASP.NET Core, Blazor, MAUI improvements, AI innovations, and the Visual Studio 2026 launch.
  • Day 2: Deep dives into Azure (Cloud keynote, Functions, Kubernetes Service, Container Apps), testing platforms, container optimizations, security best practices, and package management with NuGet.
  • Day 3: Community contributions including clean architecture principles, Xamarin.Forms to .NET MAUI migrations, observability, REST API upgrades with MCP, and advanced C# and F# features.
  • Student Zone: Beginner-friendly projects in C#/.NET covering AI, web, mobile, and game development.
  • International Reach: Broadcasts and support for Chinese .NET community members.

Technical Deep Dives

AI & ML Innovations

  • Microsoft Agent Framework: For building multi-agent, intelligent applications with support for concurrent workflows and rich Agentic UI.
  • Microsoft.Extensions.AI: Unified AI abstraction across providers.
  • Model Context Protocol (MCP): SDK for connecting AI applications with external tools and services, already deployed in Xbox Gaming Copilot and Copilot Studio (Blazor WebAssembly).
  • AI Foundry, GitHub Copilot: Modernizing applications and generating tests using AI, rapidly upgrading codebases and improving coverage.

Developer Experience

  • GitHub Copilot: Integrated as an AI pair programmer for modernization, refactoring, test generation, code suggestion, and migration to Azure cloud.
  • Performance Upgrades: .NET 10’s JIT improvements, hardware intrinsics, NativeAOT, and runtime optimizations.
  • Security: Expanded post-quantum cryptography, hardened defaults, and secure authentication flows (e.g., passkeys in ASP.NET Core Identity, Microsoft Sentinel integrations).

Ecosystem Updates

  • .NET MAUI: Android/iOS bindings, improved HybridWebView, XAML source generator, migration support from Xamarin.Forms.
  • Community: Sessions on clean architecture, observability with OpenTelemetry, API expansion, and real-world case studies.
