I am in Redmond this week to attend a DevelopMentor Web Services Guerilla course. One of my MVP's for Web Services is the instructor (Aaron Skonnard).Today the topics were to introduce us to XML (only a little) and to the Web Services architecture. It was a great introduction. We also took some time to write some HTTP Handlers. It was very interesting.I will be here a week and it is from 9 am - 9 pm, so it will be quite the time.
