In part two of this series, we demonstrated the authentication and authorization by developing an ASP.NET 2.0 web application to host the ASP.NET 2.0 AJAX 1.0 Extensions Application Services. After that, we created a Windows client application that was enabled for authentication and authorization by setting the URL of the remote services.

In this last article of the series on Client Application Services, we will show you how to load and save Profile objects enabled on the ASP.NET host application by importing them to the Windows client application as Web user settings. In addition, we will configure the application to run offline, so that all the operations covering, authentication, authorization, and profile processing will be done against a local copy of the data.
