Because a lot of developers are working with Visual Basic .NET I put the a new example online written in VB.NET. The example will be the same as the C# version. I will update both projects in the future to help VB.NET developers.
The VB.NET example is available online at http://ajax.schwarz-interactive.de/vbnetsample/default.aspx , the C# example at http://ajax.schwarz-interactive.de/csharpsample/default.aspx .
Both projects are available as a download for Visual Studio .NET 2003: http://ajax.schwarz-interactive.de/download/ajaxsample.zip .
Updated documentation can be found at http://ajax.schwarz-interactive.de/download/ajaxguide.doc .
