you've got (at least) two options at your disposal: a. the invocation object has a reference to the object it was running on (I don't remember the name of the reference by heart). you can then grab the dictionary from there using reflection a'. better yet, have the dictionary be an explicitly implemented interface, and get typed access for it in the interceptor, without polluting your entity's API b. you could also keep the dictionary on the interceptor instance (and make sure you have interceptor per entity and not as singleton) which will make accessing it a breeze. example for something similar can be seen here: http://daniel.wertheim.se/2010/02/05/getting-started-with-mongodb-using-json-net-and-castle-dynamic-proxy/ <http://daniel.wertheim.se/2010/02/05/getting-started-with-mongodb-using-json-net-and-castle-dynamic-proxy/>
