As requested I've posted the code from today's webcast on Application Services. We covered how to take advantage of the membership and profile providers and leverage the login controls that come as part of the .NET framework. We also looked at how AJAX and WinForms applications can build off the same provider database.
If you're interested in diving deeper into Application Services and/or have suggestions of topics you'd like to see covered in this webcast series, click the "Talk to me" link in the left hand pane of www.BenkoTips.com to send me an email with your ideas. I'm always looking for your feedback.
