    I used to be able to just detect design-time in the page constructor and hook-up some view models with some fake data. This no longer seems to work; I set the DefaultViewModel but the IDEs still say that there's no DataContext set, but it works at runtime.

    I take it something has changed from WP7, SL and WPF. How do we simply add fake values to TextBlock controls? There's no fallback value either.

    P.S. I didn't know about the dark "Blue Thunder" (my name) VS theme until this series, so I'm pleased if I only learned that Wink

    @LukePuplett: Hi Luke, I'm sorry I don't have an answer for you here.  I was not aware that anything changed, but I'm definitely not an authority on these matters.  If I come across anything I posted it here.  Sorry!

    @Beau: Thanks Beau!  Unfortunately I have no coupon codes or anything like that.  There is a sale going on for our 10 years anniversary ... since it will be year 11 here in a few days, I would jump on that quickly.  Smiley  Best wishes!!!
