Well I suppose I can talk a little about it now - after all it seems like happening. For the last few months I and a few other colleagues of mine are writing a book on Indigo, now called WCF (Windows Communication Framework). I personally am quite fascinated by communication and all the challenges that brings to the table. The book is titled “Pro WCF: Practical Microsoft SOA Implementation” and will be released later this year. You can get more details on it here . As and when I get more time, look out for more details on Indigo from me here including details of the other authors - who I have nicknames as the Indigo Amigos. Feel free to drop me a note if you have any questions on Indigo and I’ll try my best to get back to you, however between fighting fires at work and trying to finish the chapters, I don’t have too much bandwidth left. :)
