Summary
In this chapter, we looked at the fundamentals of extension development with the AL Language, along with an overview of the main objects for creating applications (tables, table extensions, pages, codeunits, and so on) and how to create them with Visual Studio Code. Then, we had an overview of the best practices for handling an AL project (project organization, object IDs, naming conventions) and guidelines for writing better code by focusing on the extensibility aspect of our extensions.We learned how to create objects, how to create an AL project, how to handle its structure, and how to stick to naming conventions with objects.In the next chapter, we'll implement a real-word extension for Dynamics 365 Business Central by applying all these rules and best practices.
