Very promising project for creating AJAX based applications on ASP.NET 2.0. It seems it will be released next year, and features set looks good. Atlas Project will include new controls with AJAX support, like auto-complete textboxes, drag and drop, client side paging and sorting in DataView and so on; object-oriented script framework; web services integration.
With this feature ASP.NET may greatly improve UI and this will be very good reason for developers to migrate to ASP.NET. We’ll see.
