This is another Silverlight sample application I've put together, this one concetrates on ASP.NET AJAX application services and includes all the commonly used stuff like authentication, role and profile data usage. The sample code shows how to use ASP.NET AJAX application services with Silverlight and also shows how to call the application services asynchronously and handle callbacks to the Silverlight application. This is all enabled server side using the standard ASP.NET 2.0 membership database in a SQL Server 2008 db. Source code is freely available for download as usual. Please visit my DASP hosted website for more information about this project, to run the sample and to download the source code: http://www.jjssoftware.co.uk/appservices.aspx. Enjoy!
As an afterthought, I thought it's worth highlighting that the same functionality demonstrated in this application is also now achievable using the May 2009 preview of the .NET RIA Services (with Silverlight 3). The .NET RIA services project is early in the development cycle and Microsoft openly admit that functionality will change and/or break over time, but I personally believe there is much to be gained in this area in future.
