Copilot in Your Apps over Rectangular (SQL) Data [edited]

I recently showed a pretty cool demo in a State of .NET event showing how to use a custom Copilot in a custom application over data from SQL Server. It's a fun demo, because it shows a few things that are generally considered limitations of Large Language Models (LLMs). In particular, this demo includes a Copilot (which uses Azure OpenAI) which searches and reasons over data in dozens of tables. [edited]
