You’ll see how agents can communicate, share context, and split responsibilities across workflows. We’ll discuss patterns that work, common pitfalls and how to get the best results of making AI Agents work together.

This session is for developers who already know the basics of AI applications and want to bring them into production with confidence.

Making your existing applications ready for AI agents integration

AI agents are getting better at completing full business tasks & processes. But they need a way to work with your existing business applications & data.

This session shows you to get your current business applications ready for this. Using Model Context Protocol (MCP), you can make your current .NET APIs and Azure Functions available to AI agents with minimal changes. You will see how to extend your application so agents can ask questions, take actions, and work with your data.

We will walk through the theory of how works, talk about pitfalls & patterns and the session is full of demos showing you how to get your current application ready to connect with AI systems.

After this session you'll have some clear steps of making your own business applications ready to be interacted with by AI Agents

Letting agents control your webbrowser. What could go wrong?

2025 is the year of Agents. Last year, we mostly built applications that created text or searched through your business data with RAG. Now, we're giving generative AI more power by using agents. What makes agents different is their ability to perform tasks or run actions themselves.

In this talk, we'll look at one specific agent as an example: an agent that uses a web browser just like a human would. While a browser agent can be a powerful tool in your AI agent toolbox, the principles you'll learn from this agent can apply to connecting any kind of system, service, or API.

We'll talk about a new protocol called MCP (Model Context Protocol), explaining how it enables seamless connections between AI agents and virtually any system or API.

In this session you'll learn to understand the broader application of MCP for agent integration or making your own applications MCP ready, and discover when it's smart to use these agents, when you shouldn't, and what could possibly go wrong.
