Simone has created another survey concerning AJAX usage with ASP.NET. The results are available, now, and it is really interesting to see that there are only small changes in the use of AJAX libraries for ASP.NET developers.
The most used Ajax/JS library among .NET developers is jQuery, which is used by the 71,4% of the users. Second comes the Ajax Control Toolkit with 58,8%, followed by the core ASP.NET Ajax library, which is used by 44,8%.
The 3 most used libraries are still the same of 2007, just with the opposite order (it was ASP.NET Ajax, the Control Toolkit and then jQuery).
He writes more about the results concerning my library:
Here are the results in more detail:
|AJAX Control Toolkit||49,6%||58,8%||9,2%|
It is really interesting that there is only one big change, jQuery become the new #1, I use jQuery in combination with my own library since the very beginning, and this combination is still what I recommend to use.
If you have a look at the CodePlex download statistics you can see that Ajax.NET Professional is still alive:
