I built a zero-dependency C# Vector Database that saturates DDR5 RAM bandwidth

If you’re building AI apps today, you eventually need a Vector Database for RAG (Retrieval-Augmented Generation) or giving your agents long-term memory. The current ecosystem’s answer to this problem usually involves one of three things: Pay for a cloud service. Spin up a massive Rust, Go, or Python Docker container locally (like Qdrant, Chroma, or Milvus). Use a bloated wrapper library that pulls in 50MB of dependencies just to do math. I’ve been a software engineer for 40 years. I despise bloat. I don't use heavy data-access frameworks or massive client-side libraries.
