This is exactly the type of problems the event sourcing pattern tries to solve. If we preserve all the events that led up to the current state, we can replay history and derive the current state from that, but we also open the door for more flexibility in our system.

During this workshop we will explore all the concepts that are associated with event sourcing. We will use C# to implement an event sourced system over the course of the workshop, so we can see things in practice. Our framework of choice will be Marten, an open-source, production-ready event sourcing framework in .NET.

In this workshop, we'll build an application that embodies the good practices we recommend in OpenTelemetry, and look at how those translate into good observability practices when looking at production applications.



Getting started, through to telemetry curation

Observing Event Driven Architectures (RabbitMQ, Azure ServiceBus, Kafka)

Local Visualisation techniques using .NET Aspire

OpenTelemetry Collector's and where they fit

Naming consistency through OpenTelemetry Weaver

You'll come away with a deep understanding of why Observability is important, how it's changed, and why it's now part of your job not simply an "Ops problem".

Modern Observability for .NET Applications

CSS is one of the fundamental building blocks of the web, and it's not just about making websites look pretty. Layout, accessibility, responsive design, validation, interaction - understanding CSS is vital to creating usable, accessible web and mobile applications. But let's face it - CSS is also weird. No functions, no control flow... in fact, some people say it isn't even a real programming language.

Dylan Beattie's been building web applications since before CSS was invented. (Yes, really.) In this hands-on workshop, he'll show you everything you need to know to make CSS a trusted part of your engineer's toolkit, from fundamental principles like selectors and specificity, to modern web standards like CSS grids, flexbox, variables and transitions. Learn how to build interactive forms and dialogs that work flawlessly on everything from mobile phones to projectors; how to use scoped CSS to target components and subsystems, and how to plan, deploy and test CSS just like you would any other code that's being deployed to production.
