Remarks

When an entity type is generated by the Entity Data Model tools, the ReportPropertyChanging method is called before a property change to cache the current value of the property in the IEntityChangeTracker so that this value can be used as the original value for the property.

This method calls the EntityMemberChanging method in the change tracker.
