How Not to Build a Data Platform: Lessons from Failure to Success

Building a data platform is not just about technology. It’s about adoption.

In this session I’ll share the hard-learned lessons from a data platform initiative that failed because we never engaged the business end-users it was built for. The architecture was sound and the pipelines ran, but nobody came.

You’ll learn why selling the platform’s value to stakeholders is as critical as the engineering. You’ll also see how aligning with real business needs turned that failure into a success.

You’ll leave with practical strategies for making your data platform a cornerstone of business decision-making instead of a forgotten project. These are the foundations that make later work, such as AI on top of your data, actually pay off.

19:00 - 20:00

Building Production AI Agents with Microsoft Agent Framework and .NET

AI agents are now everywhere, but how do we move beyond demos and actually build, debug, deploy, and operate them as real software?

In this session, we explore Microsoft Agent Framework (MAF), the next generation agent framework for .NET developers. Starting from familiar C# code, we will build an intelligent agent that can reason, use tools, maintain state, and collaborate as part of a larger agentic system.

But building the agent is only half the story. We will take our agent from local development to production using Microsoft Foundry Agent Service, showing how hosted agents provide a managed runtime with deployment, scaling, observability, and enterprise-ready operations.

Along the way we will look at:

  • Creating agents with Microsoft Agent Framework in .NET
  • Adding tools and real-world capabilities
  • Designing workflows and multi-agent patterns
  • Connecting with Microsoft Foundry
  • Deploying and running agents as hosted agents

If you are a .NET developer wondering where you fit in the new world of AI agents, this session shows that the answer is simple: right at the center of it.
