Замечания

The GetDependentEnd method applies the following rules (in order of priority) when returning the dependent end of an AssociationType object:

If a referential constraint is defined on the association, the dependent end (as specified by the referential constraint) is returned.
If the multiplicity of the association is one-to-one (1:1) and OnDelete="Cascade" is defined on one association end, then the other association end is returned. If OnDelete="Cascade" is not defined on either end, then the first element in the AssociationEndMembers property of the association parameter is returned.
If the multiplicity of an association is one-to-many (1:*) or zero-or-one-to-many (0..1:*) the association end with multiplicity of many (*) is returned.
In an association with multiplicity of zero-or-one-to-one (0..1:1), the association end with multiplicity of zero-or-one (0..1) is returned.

The GetDependentEnd method is used by the Generate Database Wizard when generating a database from a conceptual model.
