The Mix 07 talk has been posted for what I have been working on for the last year:
Rapidly Building Data Driven Web Pages with Dynamic ADO.NET
Speaker(s): Samuel Druker - Microsoft, Shyam Pather - Microsoft
Come learn about how new technologies from Microsoft bring together the concepts of dynamic languages and ADO.NET and allow you to quickly develop data driven web pages using ASP.NET dynamic data controls, scalable to even the most complex databases.
More information to come in the new few weeks, but all I can say at this point is that the experience has been very dynamic. And if you can’t make it to Mix07, we should have some screen casts and white papers available some time in the next several weeks.
