The same support assistant, a third time: .NET on Azure.

Fruitless Research's site has an "Ask a question" assistant that answers from the plugin manual, built on Cloudflare, and rebuilt once on Databricks. This is the same system a third time: ASP.NET Core and EF Core, the same 219 passages in Postgres with pgvector and full-text search, Claude writing the answer only from what was retrieved, the same evaluation set. The code is public at github.com/twwalsh/dotnet-rag.

Retrieval and generation run in an Azure Container App; this page only carries the question there. It knows nothing about orders or people. Answers are generated and can be wrong.
