Show GN: Cadenza: A Minimal SDK Maximizing the Utility of .NET 10 File-Based Apps

Cadenza is a bundle of SDKs supporting single-file scripting in a .NET 10+ environment, offering a development experience similar to the PEP 723 experience provided by Python's uv. As long as the latest .NET SDK is installed, you can write and run code immediately without any complex additional setup.

The main SDK types are as follows:

• Cadenza: Console scripts and CLI utilities
• Cadenza.Worker: Background services and daemons
• Cadenza.Web: Web APIs and Minimal API scripts
• Cadenza.Mcp: MCP (Model Context Protocol) servers for AI agents such as Claude, Cursor, and VS Code
• Cadenza.Agent: MEAI-based local AI agents

In particular, the AI agent development feature is powerful. You can connect local models such as Ollama, or configure agents by defining custom tools such as file system access. Agents built this way can be built and deployed as a single executable or as a Docker container image.

It is highly accessible, as development is possible using only VS Code's C# extension, without a Visual Studio license.
