Example incorrect because the suffix is _myExtension instead of _Extension

According to the task the method extensionMethodDayOfWeek() is a new method, not an extension method. So there is no need for the "next" keyword.

I would prefer A. The required method is new, so no next is allowed because we have no CoC here. To use _Extension is a reasonable recommendation but not requiered.

1. you would need to create a new class that extends SalesLineType and add the method directly to this new class, rather than using CoC. 2.CoC cannot be used to add new methods to a class.
