Extending Microsoft Dynamics 365 for Operations Cookbook

Using Interfaces for extensibility through metadata

Interfaces enforce that all classes that implement them also implement the methods defined in the interface. This has all the traditional benefits associated with them, but in Dynamics 365 for Operations, we can go further.

We should create an interface called MyRunnableI with a method called Run() and a class that implements it called MyRunningPerson (which must have a method called Run()). We can assign an instance of MyRunningPerson to a variable of type MyRunnableI and call its Run() method. This allows greater flexibility and extensibility of our code.

However, in Dynamics 365 for Operations, we can create a plugin framework where the class to instantiate is configured in data. We can, ...
