I’ve just added PDF and CHM versions of “Windows Azure Service Bus Developer Guide”, you can get them here.
The HTML browsable version is here.
I have the first delivery of my 2-day course “SOA, Connectivity and Integration using the Windows Azure Service Bus” scheduled for 3-4 May in Stockholm. Feel free to contact me via my blog if you have any questions about the course, or would be interested in an on-site delivery. Details of the course are here.
