Entity Framework after save event

entity-framework entity-framework-6

Question

Is there a SaveChanges event that fires after changes are saved, but before the change tracker is updated?

I am using EF 6.

I need to perform a task whenever the status changes on a certain entity.

I have overridden SaveChanges to set this up. I can use ChangeTracker to tell what changes. When it's the correct entity with the correct change I fire of my code.

After the base SaveChanges is called, ChangeTracker no longer shows the entity as modified, so I need to do my task just before I save. However, there is a chance that SaveChanges will fail and I should not have done my task.

How can I hook into the ChangeTracker after the save, but before the model and ChangeTracker is updated?

Can you override the save changes method?

//you will use a different dbcontext name than faroutEntities5
public partial class faroutEntities5 : DbContext
{
    public faroutEntities5()
        : base("name=faroutEntities5")
    {
    }

    public override int SaveChanges()
    {
        ChangeTracker.Entries()....

        return base.SaveChanges();
    }

Unable to save new Entities with One-To-Many relation in Entity Framework

The moment when you create the Entity2, Entity(1) is not yet in the database and Entity2 needs to have 1 available to create itself. You do right thing to call SaveChanges() to create Entity(1) first.
