Remarks
Implement IExtensibleObject<T> to enable aggregation of extensions.
For example, if you are implementing a TreeNode class and want to allow external code to add annotations and methods to some instances of TreeNode, you can have TreeNode implement IExtensibleObject<TreeNode>. This enables code that uses TreeNode to add objects that implement IExtensibleObject<TreeNode> to the Extensions collection.
There are four extensible objects in Windows Communication Foundation (WCF):
For a discussion about how to create extension to work with these objects, see Extensible Objects.
