A conference session walkthrough covering the AI building blocks available for .NET/C# developers. Topics include Microsoft Extensions for AI (provider-agnostic chat abstraction), connecting to cloud models (Azure AI Foundry, OpenAI) and local models (Ollama, Foundry Local), RAG pipelines with embeddings and vector stores, MCP (Model Context Protocol) integration using the C# SDK, and the Microsoft Agent Framework for building single and multi-agent workflows. Live code demos show chat completion, in-memory and SQLite vector search, data ingestion pipelines, MCP tool calling against Microsoft Learn docs, agent-to-agent (A2A) communication, and image generation as an agent tool. Resources referenced include the official AI for .NET docs and the Generative AI for Beginners .NET sample repo.
