I’ve just published the official release version of “The Developer’s Guide to AppFabric”. After receiving some great feedback from people I’ve corrected some errors and typos. There’s no new content since the CTP, but I’m busy working on that and there will be a lot more coverage of brokered messaging in the November release.
