Clemenscomments that Don Box's talk on Indigo showed the importance of design and architecture, not so much in demo code, but in the content of his message:
Simply hacking up an app won’t let you play in a connected application ecosystem that’s powered by Web services. WinFX will enable better applications by simplifying coding complex applications in a big way and making developers more productive. You’ll code less. Code isn’t all that matters. Architecture matters. Negotiation and contracts matter. Design matters.
So very true. The sense I get from reading all the material coming through the PDC blogger filters is that design and architecture do matter, and its going to get more important as we get into new development. Very exciting!
