Where Are We?

The CLR provides a rich architecture for viewing method invocation as an exchange of messages. The key to this architecture is the transparent proxy facility provided by the CLR's remoting library. Transparent proxies live at the boundary of the world of call stacks and allow developers to view the world as a pipeline of message filters. The CLR also provides a strong notion of context, which allows one to transparently integrate interception into a type-centric programming model.
