The components and capabilities of the product, the core solution and extensions approach, how customisations survive an update, the differences between the online and on-premises versions, the distinction between the base app and the system app, what apps do and how one reaches the marketplace.

Installing and configuring the development environment, managing the configuration files for an extension, working with several extensions in one workspace, debugging in the editor, deploying an extension, creating and modifying one, multilanguage development and keeping extensions maintained.

Tables, table extensions, page types and role centres, enums, reports including layouts, data models, triggers, request pages and multilanguage, XMLports and their properties and nodes, codeunits with events, triggers, interfaces and install and upgrade code, entitlement and permission set objects including inherent permissions, and queries with joins, filters and aggregation.

Profiles and views in code, the user assistance model, assisted setup, teaching tips, tours and onboarding checklists, the data process model and functional table types, document and master data standards and their design patterns, and the language itself: procedures, data types, files, expressions, built-in functions and statements, variables, error handling and access modifiers.

Testing applications, installing and running the test toolkit, writing test codeunits and procedures, and telemetry: monitoring and analysing it, configuring it, and emitting custom signals from an extension.

Calling external services with the HTTP classes, reading and writing JSON, creating and working with API pages, bound and unbound actions in OData, and using read scale-out to improve the performance of read-heavy work.
