Is direct reference = static reference?
Because we can only refer to an object of a class through a field or through
a constructor. Static references refer to the class directly.Sorry for
insisting on that but I want to implement this thing correctly.

Yes! This is the correct interpretation.
Usman, please do it like suggested by Simon.
So, we keep the duplicates in MSE. Ok I'll change VerveineSharp to
implement
this interpretation. But I do not understand what is mean by
direct and indirect references because as I understand the meta-model
provides only one type i.e. a Reference class to instantiate references. How
do we do the different between direct and indirect?
What Simon meant is that in the code there is no Reference to class A.
There are only calls to the constructor A. And a call to a constructor can
be considered an indirect reference. But, the model should only represent
what is found in the code.
