Exploring Interface Implementation: A Journey from Events to Enums

Dynamics 365 ERP - Development

Natalie faced the challenge of replacing an event-driven feature with interfaces to allow for multiple implementations.
Initially, the command queue pattern was considered, but the complexity led to exploring other solutions.
A metadata search over assemblies in C# was proposed as a potential solution.
An event solution was presented using a codeunit to expose a list via an event for manipulation.
The issue with the event solution was the lack of fixed execution order for event subscribers.
The use of enums in AL to implement interfaces was highlighted as a unique feature.
Enum values can be searched for interface implementations, ensuring a predictable order of execution.
An example was provided demonstrating how to implement interfaces using enums in AL.
