Personentity with a
Nameproperty we can basically be in 2 major scenarios:
Personinstance is changed, however from the user perspective maybe it's not since the
Nameproperty has the exact same value as when it was instantiated.
GetPropertyState(entity, property)method of
ChangeTrackingService, given a tracked entity and a property name, returns the current state of the property as seen by the tracking service.
None: The property has no tracked states, thus is not changed either;
Changed: The property has tracked states, thus has changes; This means that in some way the property changed over time, this state does not take into account the actual value of the property;
ValueChanged: The property has tracked states and the actual value is different from the original one;
ValueChanged. On the contrary the second one is
Changedonly, because the memento service has tracked some changes but the current value is the same as the original one.
IsPropertyValueChanged(propertyName): Is an extension method to
IMementoentities that acts like a shortcut to get if a property value changed over time or not;
