Methods

  Name Description
Public methodSupported by Silverlight for Windows Phone BuildChannelFactory<TChannel> Initializes a channel factory for producing channels of a specified type from the binding context.
Public methodSupported by Silverlight for Windows Phone CanBuildChannelFactory<TChannel> Returns a value that indicates whether the binding element can build a channel factory for a specific type of channel.
Public methodSupported by Silverlight for Windows Phone Clone When overridden in a derived class, returns a copy of the binding element object.
Public methodSupported by Silverlight for Windows Phone Equals(Object) Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected methodSupported by Silverlight for Windows Phone Finalize Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)
Public methodSupported by Silverlight for Windows Phone GetHashCode Serves as a hash function for a particular type. (Inherited from Object.)
Public methodSupported by Silverlight for Windows Phone GetProperty<T> When overridden in a derived class, returns a typed object requested, if present, from the appropriate layer in the binding stack.
Public methodSupported by Silverlight for Windows Phone GetType Gets the Type of the current instance. (Inherited from Object.)
Protected methodSupported by Silverlight for Windows Phone MemberwiseClone Creates a shallow copy of the current Object. (Inherited from Object.)
Public methodSupported by Silverlight for Windows Phone ToString Returns a string that represents the current object. (Inherited from Object.)

Remarks

A binding consists of an ordered set of binding elements that inherit from this abstract base class. For example, the TransportBindingElement class, which is the only binding element required by the service model in a binding, inherits from the BindingElement class.

Creating a binding and binding element for your transport is optional if you are just using the channel model. It is possible to do everything you need through the channel factory as long as it is made public.

The service model uses a factory pattern where the binding is used to create the channel stack. If you want to use the service model, then using a transport binding element is required. Placing this binding element into a binding is a good practice because it removes the requirement for users to create their own custom binding for your transport.

On the sending side, a binding is used to build a IChannelFactory, which in turn builds a channel stack and returns a reference to the top channel in the stack. The application can then use this channel to send messages.

Examples

The following example shows how to add a transport binding element to a custom binding and then build a channel listener that can accept incoming messages.
