LangChain
Basic Information
LangChain .NET is a C# implementation of the LangChain abstractions intended to help developers build applications that use large language models through composable building blocks. It aims to mirror the original LangChain design while remaining open to new entities and third party libraries. The project provides providers and model wrappers for services such as OpenAI, embedding models, document loaders, vector databases and chain orchestration patterns. The repository includes examples, tests and a wiki to guide usage, and positions itself as a community-driven effort to unite C# developers working on LLM applications. The maintainer highlights quick PR turnaround, invites contributors, and provides support channels and sponsorship information.
