Unlocking Dynamics 365 Finance and SCM: A Deep Dive into Extensibility Dynamics

1. Sealing the Application:

- The presentation emphasizes the importance of sealing the application to enable faster updates and hotfixes, particularly crucial in a cloud environment.

- Extensions play a key role in isolating changes, with Microsoft's application suite assembly protected and only modified by provided hotfixes.

2. Extensibility Features:

- Extensibility in Dynamics 365 includes adding new model elements, modifying existing ones, and using class augmentation features like Chain of Command.

- The goal is to enable partners and customers to customize without resorting to traditional techniques like overlaying, ensuring easier upgrades and updates.

3. Extension Examples:

- Examples cover various extension types, such as forms, tables, enums, and classes, with step-by-step guides on creating them and incorporating additional logic.

- Enum extensibility requires marking enums as extensible and ensuring switch statements are hookable or have delegates for partner code integration.

4. Application Areas for Extensibility:

- Extensibility is explored across different application areas, including data entities, queries, menus, and reports.

- Delegates and chain of command methods are highlighted as powerful tools for handling events and customizing behavior without relying on overlayering.

5. Future Expectations:

- As Dynamics 365 evolves, the expectation is to limit intrusive customizations and encourage the adoption of extension models.

- Certain limitations exist, such as changes to method or type definitions, as these define the system's contract with partners, ensuring a balance between flexibility and system integrity.
