'Usage
Dim instance As Component

Component is the base class for all components in the common language runtime that marshal by reference. Component is remotable and derives from the MarshalByRefObject class. Component provides an implementation of the IComponent interface. The MarshalByValueComponent provides an implementation of IComponent that marshals by value.

You can host a Component in any object that implements the IContainer interface, and you can query and get services from its container. The container creates an ISite for each Component it contains. The container uses the site to manage the Component and is used by the Component to communicate with its container.

A Component should release resources explicitly by calls to its Dispose method, without waiting for automatic memory management through an implicit call to the Finalize method. When a Container is disposed, all components within the Container are also disposed.
