Thanks for the session! I couldn't reproduce your 'orderHint' demo using Graph Explorer neither on beta nor on v1.0 endpoint. I keep getting weird errors from Graph.
please check out OfficeDev repo on GitHub http://gihtub.com/officedev for starter projects and http://dev.office.com/code-samples for comprehensive list of code samples where you can find not only asp.net but also Windows Store, Xamarin, Cordova...
There is also a nice intro article on ITUnity which explains basic way of programming against O365 APIs from scratch http://www.itunity.com/article/programming-office-365-apis-general-availability-release-678
