You use the IgnoreAttribute attribute to ensure that a method on a domain service is not exposed as a domain operation.

The following example shows a method in a domain service that is called by a domain operation, but is not exposed as a domain operation.

Public Sub InsertCustomer(ByVal customer As Customer)
    If (customer.SalesPerson = String.Empty) Then
        customer.SalesPerson = RetrieveSalesPersonForCompany(customer.CompanyName)
    End If

    If ((customer.EntityState = EntityState.Detached) _
                = False) Then
        Me.ObjectContext.ObjectStateManager.ChangeObjectState(customer, EntityState.Added)
    Else
        Me.ObjectContext.Customers.AddObject(customer)
    End If
End Sub

<Ignore()> _
Public Function RetrieveSalesPersonForCompany(ByVal companyname As String) As String
    Dim salesPersonToAssign As String = "unassigned"

    Dim customers As List(Of Customer)
    customers = GetCustomers().Where(Function(c) c.CompanyName = companyname).ToList()

    If (customers.Count > 0) Then
        salesPersonToAssign = customers.First().SalesPerson
    End If

    Return salesPersonToAssign
End Function
