A custom channel sink property would be specified with an attribute/value pair. In the example:
the Custom sink provider data can also be specified here. Only one level of nodes is supported. In the example: the extra information will be available as an ICollection of SinkProviderData in the constructor of the provider. |
Required Attributes
| Attribute | Description |
|---|---|
| id | Specifies a string that identifies this channel sink provider. Others can use this string in their ref attribute to bind to this channel sink provider. |

Example
The following configuration file uses a <provider> instance element to assign to the HttpChannel the "propsetter" and a "null" channel sink provider that themselves were declared with <provider> template elements. In addition, the "propsetter" channel sink provider will be created with the custom provider properties specified as attributes on the provider instance element and as the child <endpoint> attribute name/value pairs.
