Business value

We are continuing our efforts to make the core application leaner, more extensible, and easier to localize by extracting our system logic into modules that form a system application and an application foundation. These modules focus on simplicity by following a one feature = one module principle. Each module encapsulates complexity and replaces implementation details with clean, documented, and stable APIs. They speed up the development cycle and make it easier to monitor and optimize functionality from security and performance perspectives. The number of modules can vary depending on the configuration, and you can extend each module individually. Because this is a major shift in the development paradigm for both Microsoft and our partner community, we’re making the source code for each module available ahead of 2020 release wave 1.

Feature details

When we finish modules, we publish their source code in the ALAppExtensions repo on GitHub. We encourage you to explore it and provide direct feedback and make contributions. The following modules are available now:
