.NET DeveloperDays 2026

6 Oct 2026 1 mins Presentations & Speaking

Woohoo we’re getting close to .NET DeveloperDays in Warsaw. I’m really excited to be there, so let’s talk about what you can listen to from me.

This year, two of my sessions were selected – Starting with Microsoft.Extensions.VectorData and RAG and Weird C# features you (don’t) need to know about.

LLMs are everywhere, but what if you don’t want to build just a plain smart chat, but you want to infuse it with your internal data? And what if the data is changing fast? Microsoft.Extensions.VectorData and RAG might be the correct and easy path for you to solve this.

C# is a mature language with a surface most developers know well – but beneath it lurk features that are obscure, misunderstood, or simply bizarre. This talk digs into the dark corners.

Let’s have fun together there.
