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)
    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
public void InsertCustomer(Customer customer)
    if (customer.SalesPerson == String.Empty)
        customer.SalesPerson = RetrieveSalesPersonForCompany(customer.CompanyName);

    if ((customer.EntityState != EntityState.Detached))
        this.ObjectContext.ObjectStateManager.ChangeObjectState(customer, EntityState.Added);

public string RetrieveSalesPersonForCompany(string companyname)
    string salesPersonToAssign = "unassigned";

    List<Customer> customers = GetCustomers().Where(c => c.CompanyName == companyname).ToList();
    if (customers.Count > 0)
        salesPersonToAssign = customers.First().SalesPerson;

    return salesPersonToAssign;
