Two weeks ago I announced the Msdn ultimate giveaway contest. A lot of people published great comments to the post which made it a really hard decision for me. I finally had to decide and I have based my decision on the following criteria: Relevancy to web services interoperability, amount of implementation details, and presence of rationale behind the details.
It was a tough decision and a very close call. I learned a lot from your responses and thank you all for participating.
