I've just bought this book, and the first thing I try to download is Ajax.NET, as mentioned in chapter 7. I follow the link, and only the source is there.

I have looked at http://www.ajaxpro.info/ and have downloaded the zip files, but the zip files contain Ajax.2.dll, ajaxpro.dll, ajaxpro.json.2.dll and ajaxpro.json.dll.

Can someone tell me where I can get ajax.net from, and/or what is the connection with ajax.net and these other 4 dlls?

The book is supposed to explain how to get started with ajax, but, as soon as I try something practical there is a problem.

Thank you.
