Since today Amazon.com lists my new book Pro SQL Server 2008 Service Broker for preorder. Regarding the expected delivery of SQL Server 2008 in Q1/Q2, I'll try to release the book in June 2008.
I also welcome Remus Rusanu - ex software develop engineer in the SQL Service Broker team - as an guest author. Remus writes the complete 12th chapter, where he talks about administration and troubleshooting of Service Broker applications. Remus will also write about the tool ssbdiagnose.exe that helps you to find errors in a distributed Service Broker configuration.
