Microsoft AL application foundation modules and application add-ons for Microsoft Dynamics 365 Business Central

Welcome to the ALAppExtension repository!

This repo is a platform for Microsoft and our vibrant partner channel and community to work together to develop system modules and add-on apps in the AL language and to enable the general extensibility of Microsoft Dynamics 365 Business Central.

We’re working to make the core application thinner, more extensible, and easier to localize by extracting more and more of our system logic into modules, forming a system application and application foundation, as well as extracting business logic into add-on and localization apps. As we go, we’ll publish the source code for the modules and apps in this repo. The modules and apps are open for contributions. The apps can furthermore serve as starting point for verticalizations or just as samples for developing apps.

Microsoft will ship the contributions in upcoming releases of Microsoft Dynamics 365 Business Central, where you’ll get to enjoy the effect of your contributions.

Types of engagements

There are a couple of ways to engage with us here:

• You can grab the code and contribute to the published modules and apps. For more information, see the Contributing guidelines.
• If you’re building your own app and need something specific from us, like an event, you can help improve the general extensibility of the business logic. For more information, see the Extensibility requests section below.

Extensibility requests

The following are the types of requests you can submit to unblock your app:

• Add new integration events – Get the event you need to hook-in to a process.
• Change function visibility – For example, make a public function external or a similar change so you can call it from your extension and reuse the business logic.
• Replace Option with Enum – Replace a specific option with an enum that supports your extension. The new type enum is extensible, but all code was written for non-extensible options.
• Extensibility enhancements – Request changes in the application code that will improve extensibility.

We’ll have a look at your request, and if we can we’ll implement it asap. If we can’t we’ll let you know and briefly explain why not. When that happens, don’t be discouraged. Go back to the drawing board, see if you can work it out, and then come back and submit another request.
