            {
                return (from c in dc.Companies where c.CompanyId == companyId select c).Single();
            }
        }


    public void SaveCompany(Company company)
    {
        using (DataClasses1DataContext dc = new DataClasses1DataContext())
        {
            dc.Companies.Attach(company, true);
            dc.SubmitChanges();
        }
    }

    public void InsertCompany(Company company)
    {
        using (DataClasses1DataContext dc = new DataClasses1DataContext())
        {
            dc.Companies.InsertOnSubmit(company);
            dc.SubmitChanges();
        }
    }
}

4 Add a service reference
