The limitations of TCP are becoming increasingly evident as users demand faster and more reliable experiences, especially in mobile and high-concurrency environments. Traditional transport protocols are starting to feel like legacy bottlenecks. This is where QUIC, a next-generation protocol developed by Google and incorporated into HTTP/3, comes into play.

In this session, Woody will explain QUIC, a UDP-based protocol that offers built-in encryption, low-latency handshakes, multiplexed streams, and connection migration, all at the transport layer. You will learn how HTTP/3 utilizes QUIC to surpass HTTP/2 by eliminating head-of-line blocking and reducing connection setup times. We will provide practical examples in .NET 8 and 9 using Kestrel, HttpClient, and the System.Net.Quic namespace, enabling you to create high-performance web APIs, multiplayer services, or real-time applications with modern transport features.

Expect live demonstrations, code walkthroughs, and insights into why QUIC is faster, more resilient, and scalable. Whether you are streaming gigabytes of data or sending micro-interactions, this represents the future of networking in .NET.

Key Takeaways:
• Understand how QUIC differs from TCP and why it forms the foundation of HTTP/3.
• Learn how to configure and deploy QUIC-enabled ASP.NET Core apps using Kestrel.
• Explore the System.Net.Quic API to build custom QUIC solutions in .NET 9.
• Discover real-world benefits like multiplexing, connection migration, and TLS 1.3 integration.
• Evaluate performance improvements using practical benchmarks and use cases like file transfer, multiplayer gaming, and API calls.

Target Audience:
• .NET Developers building high-performance web APIs, games, or streaming platforms.
• Software Architects exploring modern transport protocols for scalable, real-time applications.
• Cloud Engineers and DevOps needing to understand QUIC’s operational impact on latency, encryption, and fallback compatibility.
• Performance and Security Engineers seeking ways to minimize overhead and maximize throughput in demanding environments.
