Udemy – GenAI for .NET: Build LLM Apps with OpenAI and Ollama

In this hands-on course, you’ll learn to integrate OpenAI, Ollama and .NET’s new Microsoft-Extensions-AI (MEAI) abstraction libraries to build a wide range of GenAI applications—from chatbots and semantic search to Retrieval-Augmented Generation (RAG) and image analysis.

Throughout the course, you’ll learn:

• NET + AI Ecosystem: You’ll learn about Microsoft’s new abstraction libraries like Microsoft-Extensions-AI, which makes it super easy to integrate & switch different LLM providers like OpenAI, Azure AI, Ollama and even self-hosted models.
• Setting Up LLM Providers: Configure the LLM providers—such as GitHub Models, Ollama, and Azure AI Foundry—so you can choose the best fit for your use case.
• Text Completion LLM w/ GitHub Models OpenAI gpt-5-mini and Ollama llama3.2 Model model: You’ll learn how to use .NET to integrate LLM models and performs Classification, Summarization, Data extraction, Anomaly detection, Translation and Sentiment Analysis use cases.
• Build AI Chat App with .NET and gpt-5-mini model: You’ll develop back-and-forth conversation based messaging with LLM and user where the AI maintains context across multiple user turns.  We will use Chat Streaming features when developing AI Chat Application.
• Function Calling with .NET and gpt-5-mini model: Develop a function that will trigger from OpenAI GPT-5-mini. The model returns structured JSON specifying which .NET function to invoke, along with arguments for retrieving real-time data.
• NET AI Vector Search using Vector Embeddings and Vector Store: We’ll also cover Vector Search, a powerful feature that allows semantic search based on meaning—not keywords.

You’ll learn how to:

• Generate embeddings using OpenAI’s text-embedding-3-small or Ollama’s all-MiniLM  embeddings model,
• Store these in a vector database like Qdrant
• Query the vector store with user embedding to find top matches by similarity
• Retrieve relevant data based on similarity searches—all in our .NET applications.

RAG – Retrieval-Augmented Generation with .NET

You’ll learn how to combine vector search results with LLM responses to:

• Retrieve relevant data from your own sources
• Break documents into chunks → embed them → store in vector DB
• At query time, embed the question → retrieve relevant chunks → pass them along with the user’s query to the LLM
• Get accurate, context-specific answers using your internal data from LLM
