TechDays 2010: ASP.NET Ajax 4.0

how come all of the demos are base upon raw table access and nothing with stored procedures, which 98% of the world works with.
Well,
this presentation is about a "presentation pattern", not about data access..... so, MVVM is not worried about how do you bring data from database......
Fantastic introduction
It covers all the main problems and pieces. I didn't know the light mvvm framework. I like it
Thanks very much
@Angelo Cook: 98% of the world...? Whose world? Definitely not mine. Why would I bother to create an additional layer of complexity that would have to be maintained, if I can achive the same and sometime even better performance, with well designed database.
