![Modernize your .NET applications in days using GitHub Copilot
Modernizing apps isn’t just rewriting code—it’s untangling dependencies, tracing data flows, and making changes without breaking production.
In this session, we’ll show how you can use agentic AI to take on the hardest parts of modernization: analyzing large codebases, mapping dependencies, planning upgrades, refactoring safely, while doing it all at scale.
With the GitHub Copilot modernization agent, you can move from legacy complexity to modernized apps in days, not months.

![Scaling the Claw: Skills, Shell, CodeAct and Background Agents
Four additions make the agent genuinely useful. Skills package domain knowledge such as valuation and risk scoring into files it discovers and loads only when a request calls for them, including skills managed centrally in Foundry that update with no redeploy. Shell access lets it reorganise a messy folder of trade confirmations, confined to one working directory.
CodeAct gives it a sandbox where it writes and runs code to work out an answer rather than guessing at the arithmetic. Background agents let it research several tickers at once and pull the results back together.
