Events

Learning micro-steps with "test && commit || revert"

Even if you don't use it every day, you as a developer should be able to take "micro-steps" when developing the requested functionality. Just like most other skills, you need to practice this technique. "test && commit || revert" (TCR) is a great way to enforce micro-steps and sharpen your skills. In the course of this talk, we will explore the ideas behind "test && commit || revert", the new programming workflow invented by Kent Beck, Oddmund Strømme, Lars Barlindhaug, and Ole Johannessen. After a short introduction we will dive right into an example. We will see why "losing code" can be a good thing and experience the beauty of "the test suite that is always green". But we will also loot at the limitations and problems of TCR.

Blazor: Beyond the ToDo App

There are a lot of great tutorials out there to get started with Blazor. And they all help developers get into Blazor. But not every application is a simple ToDo app. In todays enterprise applications we rarely write all the code in a single ASP.NET Core project. In this talk, we will go beyond the popular ToDo app example. We will create a small app that separates the API and the UI in different projects. This lays the foundation for more complex applications. We will also use "Project Tye" to run the projects as Docker containers and simulate a microservice architecture. There are only a few slides used for the introduction. The rest of the time will be spent in the code to see how more complex solutions can be developed using Blazor.

Server-side Blazor in Action

Not everybody loves JavaScript. Don't get me wrong. I don't hate JavaScript. But I love C#. I always dreamed about writing my frontend code in C#. Tell you what? It's possible. Even without WebAssembly. In this talk, we will dive into the the world of server-side Blazor. After a short walk through the default project template, we will create a custom component. There are only a few slides used for the introduction. The rest of the time will be spent in the code to see server-side Blazor development in action.

FeatureManagement in .NET

Continous Integration and Continous Delivery are getting more and more popular. There are companies who will the new employees push changes to production on Day 1. Sounds easy, doesn't it? But if every commit/merge to "master" leads to an update on production, what do you do with your unfinished feature? Or the feature, which has not gotten through QA, yet?

Introduction to ASP.NET Core SignalR (Workshop)

Real-time communication is used in a lot of applications. In this workshop, we will go through the steps that it takes to use SignalR in your ASP.NET Core application.

The broken windows and burning cars of software development

It does not matter if you are a Senior Software Architect with a lot of experience or are junior dev who just started his second job. The truth is you might be still responsible for bad code written at companies, you no longer work for. In this talk we will explore the basic psychology behind the "Broken Window Theory" and see, why it relates to software development so well.

Why "real world" TDD is hard and what you can do about it

Learning Test-Driven Development (TDD) is hard. There, I said it! But why is hard? And what can you do to make TDD less frustrating to learn/use? In this talk you will get to know the "missing pieces" of most TDD introductions. You will learn, why "red - green - refactor" isn't enough and how dependency injection and other techniques will help you write testable code.
