You are a Dynamics 365 Finance developer.
You need to create an extension class.
Which action should you perform?

A. Mark the class as final.

B. Add the class buffer as the first parameter.

C. Mark the class as protected.

D. Mark the class as public.








 

Suggested Answer: A

Extension classes are final classes that are adorned with the ExtensionOf attribute and that also have a name that has the _Extension suffix.
Because the classes are instantiated by the runtime system, it's not meaningful to derive from the extension class. Therefore, the extension class must be marked as final.
