I don't know if this is a new Microsoft trend or not but for the second time in the past week  I came across an important, missing or hard to find download link for a Microsoft product.

This time around the missing download is AJAX 1.0 Extensions for ASP.NET 2.0.

Normally you should be able to find the file at http://www.asp.net/ajax/ but for some reason it disappeared and only AJAX version 3.5 download links exist over there.

Could that be because Microsoft is trying to aggressively push ASP.NET 3.5. which includes AJAX version 3.5?

In any case the name of the installation file is ASPAJAXExtSetup.msi and you can find the download link at:
