Of course, first of all, happy new year! Oh, and: FIRST POST! :-)
With AX 2012, Enterprise Portal has also gotten an upgrade. It is now built on SharePoint 2010, and also hooks into the Enterprise Search features of SharePoint. As far as development goes, the new .NET story has simplified the use of proxies (of course), and MorphX list pages "just work" as EP pages without any extra effort (except clicking deploy). Of course there is a lot more to talk about!
I'm working on Enterprise Portal content for Microsoft, so it's been EP round the clock for weeks now, and not quite done yet. Of course this brings a good opportunity to share a lot of that knowledge I'm gathering with all of you readers.
So, before I start writing EP articles for this blog to add to the AX 2012 Developer Resources, what kind of questions do you have? Any particular issues, general information, development questions, follow me on Twitter and send me your questions!
