How to integrate any LLM model in C#?

Dear Hugging Face people, I’m new to AI, so there are things I don’t know yet, and I’d like to know if you can help me with the following questions:

• My PC has only 16GB of RAM and a second-generation Ryzen 3 APU, so what are the requirements I need on Windows 11 to run vicuña or another NLP model that can be integrated into a C# project? In any case, which one do you recommend or how should I do it?
• How can I train it on a certain topic once installed?
