Darren, Ewan and myself are really close to getting the book, Professional BizTalk Server 2006 out of the door, it's been hard work but hopefully it'll be worth while. The book offers insight in to how BizTalk works under the hood which will enable you to really exploit the architecture, this is blended with the lessons learned designing, developing, and operating some of the most mission critical BizTalk solutions that have been deployed around the world by Microsoft Consulting Services. I knew it would be a massive amount of work before we started, and it has definitely been that!!
As you may have seen GotDotNet is being phased out by Microsoft, because of this I've moved BizUnit to its new home at CodePlex, I have some great ideas for new features which, now the book is done I might actually get time to implement!! The latest version includes a bunch of work that we did on the last performance lab in Redmond that I was involved in, including some new test steps to enable it to be used to automate performance tests.
Aside form the book, a lots been going on for me. I left Microsoft last summer to work for a leading european investment bank, leaving after 8+ incredible years was not easy I can tell you. I had an amazing time working for Microsoft, a lot of great times. Since leaving I've been playing with a lot of different but very interesting technology, so I should get back to some blogging soon!
