I am looking at adding logic to a library I am working on that would require the need for a Dynamic Proxy. I would like to get some advice from user's who have used these two library's in a production environment. Does one out perform the other, were there any shortcoming's which made you have to switch to the other, etc. Basically tell me your experiences with the library's. The answers will help me decide which one to use.
-- Edit --
I forgot to mention that the library I am developing will support Mono, therefore any knowledge you can share about the two libraries and their support for Mono would be great also.
