Examples

The following example shows how to use this class to create a custom binding that includes this class as a security binding element. For more information about the code in this example, see How to: Consistently Reference X.509 Certificates.

public Binding CreateClientBinding()
{
    AsymmetricSecurityBindingElement abe =
        (AsymmetricSecurityBindingElement)SecurityBindingElement.
        CreateMutualCertificateBindingElement(
        MessageSecurityVersion.
        WSSecurity10WSTrustFebruary2005WSSecureConversationFebruary2005WSSecurityPolicy11BasicSecurityProfile10);

    abe.SetKeyDerivation(false);

    X509SecurityTokenParameters istp =
       abe.InitiatorTokenParameters as X509SecurityTokenParameters;
    if (istp != null)
    {
        istp.X509ReferenceStyle =
        X509KeyIdentifierClauseType.IssuerSerial;
    }
    X509SecurityTokenParameters rstp =
    abe.RecipientTokenParameters as X509SecurityTokenParameters;
    if (rstp != null)
    {
        rstp.X509ReferenceStyle =
        X509KeyIdentifierClauseType.IssuerSerial;
    }

    HttpTransportBindingElement transport =
        new HttpTransportBindingElement();

    return new CustomBinding(abe, transport);
}

Public Function CreateClientBinding() As Binding
    Dim abe As AsymmetricSecurityBindingElement = CType(SecurityBindingElement.CreateMutualCertificateBindingElement(MessageSecurityVersion.WSSecurity10WSTrustFebruary2005WSSecureConversationFebruary2005WSSecurityPolicy11BasicSecurityProfile10), AsymmetricSecurityBindingElement)

    abe.SetKeyDerivation(False)

    Dim istp As X509SecurityTokenParameters = TryCast(abe.InitiatorTokenParameters, X509SecurityTokenParameters)
    If istp IsNot Nothing Then
        istp.X509ReferenceStyle = X509KeyIdentifierClauseType.IssuerSerial
    End If
    Dim rstp As X509SecurityTokenParameters = TryCast(abe.RecipientTokenParameters, X509SecurityTokenParameters)
    If rstp IsNot Nothing Then
        rstp.X509ReferenceStyle = X509KeyIdentifierClauseType.IssuerSerial
    End If

    Dim transport As New HttpTransportBindingElement()

    Return New CustomBinding(abe, transport)
End Function

Remarks

A custom binding contains a collection of binding elements arranged in a specific order: the element that represents the top of the binding stack is added first, the next element down in the binding stack, is added second, and so forth.

To add this class to a binding

1. Create a BindingElementCollection.

2. Create custom binding elements that is above this binding element in the binding stack, such as the optional TransactionFlowBindingElement and ReliableSessionBindingElement.

3. Add the created elements in the preceding order to the BindingElementCollection using the InsertItem(Int32, BindingElement) method.

4. Create an instance of AsymmetricSecurityBindingElement and add it to the collection.

5. Add any additional custom binding elements to the collection, such as TcpTransportBindingElement.

Before using this class, you should determine if a standard binding meets your security requirements.
