Hey folks, we've just released a BUNCH of SharePoint 2010 training materials to the web today. Me and several of my good friends at Microsoft worked on these for more hours than I care to say. We wanted to make sure the content was up and available on product launch day, and both have arrived simultaneously.
You can find links for both IT Pro materials (some of which I worked on) at http://technet.microsoft.com/en-gb/sharepoint/ff420396.aspx. For developer materials look at http://msdn.microsoft.com/en-us/sharepoint/ff420377.aspx.
Just saw your webcast on customizing Search Results. I noticed a Core Search WebPart Category for Ajax Options. Is that something you are working on or OOTB? Could you please share some insight?
