How best to communicate between AppDomains?

Question

I have an application that needs to send a moderately high volume of messages between a number of AppDomains. I know that I could implement this using remoting, but I have also noticed that there are cross-domain delegates. Has anyone looked at this kind of problem?

Answer 1

I have had good success using WCF with a named pipes binding. Using named pipes creates no network traffic and uses binary encoding, so it should be pretty fast without sacrificing the ability to distribute in future scaling scenarios.
