Building AI Agents with Python and C#

Build intelligent AI agents that do more than chat.

Building AI Agents with Python and C# is a practical guide for developers, students, and technical professionals who want to design, build, and deploy real-world AI agents using two of today's most important programming languages.

This book goes beyond basic prompting and simple chatbot examples. It shows you how to create agent systems that can reason, use tools, retrieve knowledge, manage memory, interact with external systems, and operate in structured workflows.

You will learn how to build agent pipelines step by step, from foundational concepts to production-ready architectures. Along the way, you will explore tool calling, structured outputs, retrieval-augmented generation (RAG), MCP, document-aware agents, memory systems, multi-agent workflows, observability, security, and deployment strategies.

Whether you are building internal business assistants, document-review systems, research agents, workflow automation tools, or next-generation AI applications, this book gives you a practical roadmap for turning powerful models into dependable software systems.

Inside this book, you will learn how to:

• Build AI agents in both Python and C#
• Design better prompts, planning loops, and structured outputs
• Implement tool calling and safe tool design
• Use MCP to connect agents to external tools and services
• Add short-term memory, long-term memory, and context injection
• Build retrieval-based and document-aware agents
• Design single-agent and multi-agent systems
• Create asynchronous, event-driven workflows
• Integrate agents with APIs, databases, and business systems
• Test, evaluate, observe, secure, and deploy agents for real-world use

Who this book is for:

• Developers who want to move beyond basic chatbot projects
• Students and educators exploring practical AI engineering
• Software engineers building AI-powered business applications
• Technical professionals interested in agent architecture and automation
• Anyone who wants a structured, hands-on introduction to real agent systems

If you want to learn how modern AI agents actually work-and how to build them in a practical, scalable way-this book will help you move from experimentation to real implementation.
