Demystifying Microsoft Agent Framework Middleware

In this session we'll walk through how Daniel Costea uses ChatClient and Agent middleware to turn plain .NET AI agents into production‑ready systems with observability, safety, and cost control. Starting from an agent that talks directly to an LLM, he walks through real‑world failure modes (cost spikes, privacy leaks, unsafe tool calls) and then layers in SharedFunction, Response, and FunctionCalling middleware to fix them. Along the way, he connects each concept to the familiar ASP.NET Core middleware pattern so .NET developers can reuse an existing mental model for building robust AI agents.
