Type Parameters
- T
The type of the extension class.
- Derived
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.
