Ask Me Anything: Data Engineering in Microsoft Fabric
Join us for an interactive Q&A on Data Engineering in Microsoft Fabric. The Data Engineering team is behind the Spark runtime, notebook and Lakehouse experiences in Fabric—helping you transform, process, and manage data at scale with tools designed to boost both performance and productivity.
We’re here to answer your questions about:
- Apache Spark in Microsoft Fabric: its capabilities, performance, and features
- Best practices for building out your Lakehouse architecture
- How we’re thinking about scaling, performance tuning, and developer experiences

•OnlinePython + AI: AI agents
OnlineFor the penultimate session of our Python + AI series, we're building AI agents! We'll use many of the most popular Python AI agent frameworks: Langgraph, Semantic Kernel, Autogen, Pydantic AI, and more.
Our agents will start simple and then ramp up in complexity, demonstrating different architectures like hand-offs, round-robin, supervisor, graphs, and ReAct.
Pre-requisites:

•OnlineShifting Offensive Security Left: Rethinking DevSecOps in the Age of AI
OnlineToday’s DevSecOps pipelines excel at finding issues, but not at knowing which ones truly matter. Traditional testing tools stop at detection, while real security validation often happens late, manually, and out of band.
In this session, we’ll explore what it means to bring offensive security intelligence into the developer workflow, unifying detection, validation, and remediation in a continuous loop. Using XBOW as an example, we’ll discuss how AI-driven reasoning can help teams move from theoretical findings to proof-backed, fix-verified security that keeps pace with modern development.
You'll learn:
- Why DevSecOps needs real-world validation (not just scanning) to close the loop
- How shifting offensive testing left changes prioritization, collaboration, and velocity
- How AI is reshaping the path from vulnerability discovery to verified remediation

•OnlinePython + AI: Model Context Protocol
OnlineIn the final session of our Python + AI series, we're diving into the hottest technology of 2025: MCP, Model Context Protocol. This open protocol makes it easy to extend AI agents and chatbots with custom functionality, to make them more powerful and flexible.
We'll show how to use the official Python FastMCP SDK to build an MCP server running locally and consume that server from chatbots like GitHub Copilot. Then we'll build our own MCP client to consume the server. Finally, we'll discover how easy it is to point popular AI agent frameworks like Langgraph, Pydantic AI, and Semantic Kernel at MCP servers.
With great power comes great responsibility, so we will briefly discuss the many security risks that come with MCP, both as a user and developer.
