Question

Is it possible to to create an EF entity that allows your to create records but disable update and deletes. I have data object that I want to allow code to create records in DB but they should not be allowed to change or delete them. I’m using EF code first approach.

Answer 1

Yes you can override the SaveChanges method of your DbContext and can prevent that.

public override int SaveChanges()
{
    foreach (DbEntityEntry entity in this.ChangeTracker.Entries)
    {
        if (entity.State == System.Data.EntityState.Modified)
            return;
        // more logic, depending on your needs
    }

    base.SaveChanges();
}
