This section enables the use of a custom binding element from a machine or application configuration file. You can add a custom binding element to this collection by using the
add keyword, and setting the
type attribute of the element to a binding element extension, as well as the
name attribute to the custom binding element.
Binding extensions enable the user to create user-defined binding elements for use as part of custom bindings. Programmatically, a binding extension is a type that implements the abstract class BindingElement. In the configuration file, the
bindingElementExtensions section is used to define an extension element.
The following example uses the
add element, as well as the
name attribute to add a binding extension to the
bindingElementExtensions section of the configuration file.
<system.serviceModel> <extensions> <bindingElementExtensions> <add name="udpTransport" type="Microsoft.ServiceModel.Samples.UdpTransportSection, UdpTransport, Version=188.8.131.52, Culture=neutral, PublicKeyToken=null" /> </bindingElementExtensions> </extensions> </system.serviceModel>
To add configuration abilities to the element, the user needs to write and register a
bindingElementExtensionSection element. For more information on this, see the System.Configuration documentation.
After the element and its configuration type are defined, the extension can be used as part of a custom binding as shown in the following example.
<customBinding> <binding name="test2"> <udpTransport /> <binaryMessageEncoding maxReadPoolSize="211" maxWritePoolSize="2132" maxSessionSize="3141" /> </binding> </customBinding>
