āš” Building applications with LLMs through composability āš”
C# implementation of LangChain. We try to be as close to the original as possible in terms of abstractions, but are open to new entities.

While the SemanticKernel is good and we will use it wherever possible, we believe that it has many limitations and based on Microsoft technologies. We proceed from the position of the maximum choice of available options and are open to using third-party libraries within individual implementations.

I want to note:

  • Iā€™m unlikely to be able to make serious progress alone, so my goal is to unite the efforts of C# developers to create a C# version of LangChain and control the quality of the final project
  • I try to accept any Pull Request within 24 hours (of course, it depends, but I will try)
  • I'm also looking for developers to join the core team. I will sponsor them whenever possible and also share any money received.
  • I also respond quite quickly on Discord for any questions related to the project
