The timing couldn't have worked out any better if we had of tried. We presented our Web Service Security : Scenarios, Patterns and Implementations guide for the first time ever at the patterns & practices summit today - and I just received word that the content has just gone live on MSDN.
So, if you are interested in learning more about how to secure your web services take a look at the content on the landing page - or download the PDF from the download link. We will also have executable quickstarts available on our GotDotNet workspace later this week.
Don (http://blogs.msdn.com/donsmith) and I will start providing a more in depth drill down in blogs over the next couple of days - but just wanted to get the word out!!!
