Our book SOA with .NET and Windows Azure is now available!
I am one of the many coauthors of this wonderful book (I think ;) that takes a fundamental approach to the realization of SOA with .NET. It also adds a cloud twist by covering Windows Azure as cloud computing platforms are expected to change the computing landscape as we know it. The book is available on Amazon: https://www.amazon.com/gp/product/0131582313.
