My class is creating entries in the database and I want it to stop
public class BenefitsForm : IAnnualForm, IAuditable
{
    public BenefitsUser UserInfo { get; set; }
    public CoverageLevel Medical { get; set; }
}

public class MedicalPlan : IHealthPlan
{
    public int Id { get; set; }
    public virtual IList<CoverageLevel> CoverageLevels { get; set; }
}

public class CoverageLevel
{
    public int Id { get; set; }
    public virtual MedicalPlan MedicalPlan { get; set; }
}

BenefitsForm form = new BenefitsForm() { UserInfo = new BenefitsUser() };
using(var repo = new CoverageLevelRepository())
{
    form.Medical = repo.Retrieve(new NumericKey(formId))); //this retrieves the coveragelevel with the id I want.
}
formRepository.Create(form); // this creates a duplicate med plan and 4 duplicate coverage levels.
formRepository.SaveChanges();

BenefitsForm form = new BenefitsForm() { UserInfo = new BenefitsUser() };
using(var repo = new Repository())
{
  form.Medical = repo.Retrieve(new NumericKey(formId))); //this retrieves the coveragelevel with the id I want.
  repo.Create(form); // this creates a duplicate med plan and 4 duplicate coverage levels.
  repo.SaveChanges();
}

ObjectContext.SaveChanges(
           System.Data.Objects.SaveOptions.DetectChangesBeforeSave
                   );
