On November 5th I had the pleasure of delivering a presentation on the topic of "AJAX and Web Services" to the combined Atlanta Microsoft Professionals, Cutting Edge, and VB .Net Study groups. I discussed how we can take .asmx web services and expose them to client side JavaScript including the changes that are necessary on both the client and the server. I showed several code samples that showed passing parameters, callback functions, user context, and complex types. I also discussed client side support for ASP .Net 2.0 Profile and Authentication services. My slides can be downloaded here - enjoy. Please feel free to contact me with questions or feedback. I look forward to hearing from you
