Tired of your architecture diagrams becoming outdated before they even reach production?
In this hands-on session (Level 300), you’ll learn how to turn .NET Aspire AppHost definitions into living documentation —Mermaid diagrams, markdown, and Aspire Dashboard screenshots— powered by GitHub Copilot Chat and the Copilot Coding Agent.

Ask Copilot for an ASCII diagram of the services and resources declared in Aspire.

Automatically transform it into Mermaid and preview it in VS Code via mcp-mermaid.

Delegate to the Coding Agent the generation of a pull request that updates documentation whenever the architecture changes.

Enrich the markdown with Aspire Dashboard screenshots using Playwright MCP, creating an always up-to-date “source of truth” for your team.

By the end, you’ll know how to integrate this workflow into your CI/CD pipeline, reduce documentation debt, and deliver a reproducible blueprint for any cloud-native solution built with .NET Aspire. Bring your laptop with .NET 10 Preview installed and get ready to be amazed by Copilot’s speed!
