Join us for another episode of Sip & Sync with Azure ☕🎤 as we explore how to modernize a legacy .NET application using GitHub Copilot and Azure app modernization tools.
In this episode, host Priyanka Vergadia is joined by Krystal Folkes, who walks through an end-to-end modernization journey. Starting with a real-world ASP.NET Web Forms application, Krystal demonstrates how GitHub Copilot agents, planning mode, and security assessments can help teams upgrade legacy code, migrate databases, modernize architecture, and deploy to Kubernetes.
This session covers not just code upgrades, but also security baselining, database migration, architecture visualization, and deployment planning. Whether you’re dealing with brownfield applications or planning modernization at scale, this walkthrough shows how Copilot can dramatically reduce complexity and time-to-value.
