The agenda highlights GitHub Copilot-assisted modernization, Aspire-based approaches, migration of WinForms and line-of-business apps, and adding agentic/AI capabilities.

Apoorv Gupta explains Spec-Driven Development (SDD) as a spec-first workflow for AI-native engineering, where structured specs act as the shared source of truth across requirements, design, implementation, and validation. The post introduces GitHub Spec Kit and outlines a practical lifecycle teams can adopt to reduce ambiguity and rework.

Natalie Guevara explains how to give GitHub Copilot CLI real code intelligence by installing and configuring language servers via the LSP Setup skill, replacing brittle grep/decompile workflows with semantic features like go-to-definition, find references, and type resolution in the terminal.
