A day in the life of a Business Central developer
LEVEL: 300 - Advanced
Conference Hotel

Our world is always changing, and it is changing faster and faster. The development environment keeps getting more flexible, which means that you need to know about more things each time that a new update comes out. The sheer number of things that you need to know about can feel overwhelming.

This workshop will give you the skills that you need to get a grip on the whole thing. We will start with an empty slate, and we will go through all phases of a development project, and cover every step of the way.

You will learn how to set up a development environment using Docker, how to create a source code management repository, how to approach different ways to do source code management, how to manage a project using Visual Studio Team Services, how to build all of the elements that come with a Business Central app, how to do automatic testing, how to submit apps to AppSource and how to maintain them, and everything else that comes with being a Business Central developer.

Workshop date: Tuesday 20 or Wednesday 21 November. This is a one day workshop.

09:00 - 17:00

Rock ‘n roll with VSCode
LEVEL: 300 - Advanced
Conference Hotel

Last year, waldo did a session about VSCode – the new development environment we as NAV developers should get used to. He was asked quite some times to put that into a workshop.

Well, here you go:

This workshop will focus on VSCode as a development tool, like:

  • Its configurability
  • Its extensibility
  • Coding hacks
  • Shortcuts
  • Snippets
  • SCM
  • ...

We will be installing and configure our VSCode the way we like for doing AL development. We will dive into VSCode Extensions which will help you during Al Development. And last but not least, we will create our own VSCode Extension.


  • I will prepare Azure VMs for you for during the workshop. All you need is your laptop with Wifi!

Workshop date: Tuesday 20 or Wednesday 21 November. This is a one day workshop.

09:00 - 17:00

GIT deep dive
LEVEL: 300 - Advanced
Conference Hotel

How Git works inside, branching strategies, merge strategies, this is what you need to know to be able to use Git on full speed.

We will be using the command prompt and/or git client of your choise (could have limited possibilities) and of course VSCode to demonstrate how different commands could be used to reach what you need. After the workshop you will know what words like “stash, reflog, squash, GitFlow ” means in the context of Git and you will have overview to make decisions and create rules when implementing and using SCM.


A basic knowledge of VSCode and SCM is advantage.

Workshop date: Tuesday 20 or Wednesday 21 November. This is a one day workshop.

JavaScript for NAV Developers
LEVEL: 400 - Expert
Conference Hotel

With an advent of web, and especially the tablet and the phone clients, it became obvious that we won’t be able to pretend the Web world has infiltrated our sacred C/AL ground for much longer. All the Web technologies, HTML5, CSS, and above all – JavaScript – have entered into our world and now we need to learn how to make this new animal behave in our own backyard. But JavaScript is not an easy beast to tame. Easygoing to the point of sloppiness, and flexible as a chewing gum, cryptic even before you minify it, as beautifl and elegant as it is cruel and scary, with functions that are variables that are also properties, and expressions, and at the same time behave as if they are all booleans, where everyting is either truthy or falsy, and where == was not good enough as an operator so it also came up with ===, if JavaScript gets you royally confused, don’t worry – it’s all by design.

If there was ever a language that was as powerful as to allow you to do absolutely any kind of craziness you could come up with, but at the same time allowing you to mess things up beyond all reason, then it’s JavaScript. It can do whatever you want it to do, and it’ll let you do whatever you want to do to it. And it now talks directly to C/AL, so you better get to know it well before it starts making fun of you.

This one-day workshop led by Vjekoslav Babić, who had been a seasoned Web developer for years before jumping on the C/AL wagon 15 years ago, you will learn all the intrinsics of JavaScript that can confuse an AL developer. Not only you’ll learn all the important language features such as callbacks and closures, or harness the immense power of expressions – you’ll also learn how to write efficient code, how to not make common mistakes, and how to take advantage of amazing development features embedded into every modern browser. And above all, you’ll learn how to properly use all this together with the good old C/AL.

Hungry? Taste Machine Learning!
LEVEL: 200 - Intermediate
Conference Hotel

Have you ever ordered a dish in a cafe, but you were told that it was not available?

I did. This is a very unpleasant situation. And for both parties.

The cafe can lose the client, simply because the demand was incorrectly predicted.

In this workshop we will see how machine learning can solve this problem. What general problems can be solved through machine learning? And what is it? A fashion word or a working tool?
