Semantic Kernel + Open WebUI: Local LLM API in ASP.NET Core (without its own UI)
In this tutorial, I'll show you how to implement a local LLM API with Semantic Kernel in an ASP.NET Core WebAPI project in just a few steps – without a custom interface! Using my open source library "Ollama API Facade," you can easily connect your backend to the Open WebUI, use local language models via LM Studio, and get professional debugging with Burp Suite.
🔧 Ideal for .NET developers who want to get started quickly with local AI models and rely on a ready-to-use UI.
