The AJAX Control Toolkit for ASP.NET 2.0 has been updated. Nothing new was added, but the bug fixes are sure to be welcome. In related news, a VS 2008 Beta 2 compatible version was also released with a couple of interesting features. And in case you did not know, they are now accepting patches.
The AJAX Control Toolkit is a set of open source controls for ASP.NET AJAX. Unlike most Microsoft products, this is following the release-early, release-often philosophy. As such it lacks some of the polish you find in other Microsoft libraries. On the other hand, being open source allows developers to crack open the library and make any changes they need.
In the past Microsoft was fearful of accepting outside patches. As Microsoft is a constant target of IP litigation, they are understandably shy when it comes to integrating code with a questionable pedigree. Over the last year this has been quietly changing. It turns out that the AJAX Control Toolkit project began accepting patches via a "Patch Utility" back in April with little fan-fair.
For Visual Studio 2008 Beta 2, you get the same set of controls. Changes include support for JavaScript IntelliSense and designer support for attaching extenders. The IntelliSense features rely on "reference tags". These are specially formed comments that pull in the metadata from other scripts.
