Windows Azure Service Bus supports only Full Trust code access security.
This type is used by Windows Azure Service Bus to read information from an App.config file and create the corresponding binding. You can also access the binding programmatically, through WS2007HttpRelayBinding. As such, you will not likely to use directly, but instead use it indirectly whenever you configure a binding in an App.config file. For more information on setting Windows Azure Service Bus configuration values, see Configuring an AppFabric Service Bus Application.
However, you can use to create your own custom relay bindings, based on WS2007HttpRelayBinding. Custom bindings are optimized collections of transport, encoding, and security elements, along with other features. For more information, see Creating a Custom AppFabric Service Bus Binding.
