SecurityBindingElement Class

An abstract class that, when implemented, represents a binding element that supports channel SOAP message security.

Namespace: System.ServiceModel.Channels
Assembly: System.ServiceModel (in system.servicemodel.dll)

public abstract class SecurityBindingElement : BindingElement
public abstract class SecurityBindingElement extends BindingElement
public abstract class SecurityBindingElement extends BindingElement
Not applicable.

This class is the base class for the SOAP message security binding elements in WCF. There are three implementations of this abstract class: SymmetricSecurityBindingElement, AsymmetricSecurityBindingElement, and TransportSecurityBindingElement. These implementations model the bindings defined in the WS-Security Policy specification.

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 on.

To add this class to a binding, do the following:

  1. Create a BindingElementCollection.

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

  3. Add these elements in the order described above to the BindingElementCollection using the InsertItem method.

  4. Create an instance of a security binding element derived from SecurityBindingElement, such as AsymmetricSecurityBindingElement, SymmetricSecurityBindingElement, or TransportSecurityBindingElement.

  5. Add the derived security binding element to the collection.

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

For more information about using a SecurityBindingElement, see SecurityBindingElement Authentication Modes and How To: Create a Custom Binding Using the SecurityBindingElement.

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
