Design Patterns, Architecture Best Practices, Clean Code. Does this sound like bullshit bingo to you? In this session, we will explain why it shouldn't. We will explain why those things matter, from a technical as well as from a business perspective. If you are already convinced, maybe it also helps to convince your colleagues or managers. Then we will go into a couple of design patterns, where they can be applied and how they can be implemented in AL. Then we talk about architectural best practices and show examples how they can be implemented. After this session, you should have food for thought as well as specific ideas how to improve your Business Central development practice.
