Using the Pinecone vector database in .NET

The article discusses the integration of the Pinecone vector database with .NET for building generative AI applications. It emphasizes the importance of controlling data used in AI to prevent issues like "hallucinations," where AI generates plausible but incorrect information. To mitigate this risk, retrieval-augmented generation (RAG) techniques can be employed, which involve using a vector index to enhance the AI's ability to generate accurate responses based on relevant data. Pinecone offers a managed vector database service on Azure, which can be accessed through a .NET SDK. This SDK simplifies the connection to the database, allowing developers to create, manage, and query vector indexes efficiently. The article outlines the process of setting up a Pinecone index, including creating namespaces, upserting data, and querying the index using various distance metrics. The integration of Pinecone with .NET facilitates the development of RAG applications, enabling developers to leverage existing tools and streamline their workflows.

FYI me and Maurycy Markowski are maintaining Pinecone.NET which has been available since May 2023: https://github.com/neon-sunset/Pinecone.NET.

It is a community library for Pinecone that has been eventually adopted by SemanticKernel.

Notably, the new official SDK has a few issues as outlined here: https://github.com/neon-sunset/Pinecone.NET/pull/126#issueco...

While it is acceptable and there are much sadder examples of vendor SDKs, it will not offer the same level of experience as hand-crafted client library. In the case of Pinecone, a similar level of care is applied mainly to their Python and TypeScript SDKs.

Now, I don't particularly care for Pinecone anymore - it's a paid vector DB that does not fit my more "indie"-ish needs, and this is a very small project, but I do care about .NET having high-quality libraries. It is a core dependency anyway, therefore it will continue to be developed as appropriate.
