Why is the Context not cleared on Exception?

Question

Entity Framework

Good afternoon! Faced the problem of saving the entity in the database, after an error

dbEntities db;
        public RelationshipPeopleRepository(dbEntities context)
        {
            db = context;
        }

        public void Create(relationship_people item)
        {
            db.relationship_people.Add(item);
            db.SaveChanges();
        }

When I call Create, I get the error "Duplicate entry '108-94' for key 'PRIMARY'", I process it with try / catch and want to save information about this to a table in the database.
I'm already doing it in another repository

db.log.Add(item);
db.SaveChanges();

And I still get the error Duplicate entry '108-94' for key 'PRIMARY
What am I doing wrong?

Answer 1

Is the context in all repositories the same? If so, then in case of an error in saving the entity, it should be "unhooked" from the context:
In theory, the context after that will stop tracking the entity and will no longer try to shove it into the database.
