When I try to run a small test app in Blend 2 created by following the
directions in the User Guide titled "Try it: Playing with handoff and
nonhandoff animations" I get an error saying "WpfBas.exe has encountered a
problem and needs to close. We are sorry for the inconvenience." The error
signature says

"EventType : clr20r3 P1 : wpfbas.exe P2 : 0.0.0.0 P3 : 484595e1

P4 : presentationframework P5 : 3.0.0.0 P6 : 470bc696 P7 : 660b
P8 : e1 P9 : system.windows.markup.xamlparse"

Does this make any sense to anyone? This is my first attempt to use WPF and
Blend, so my confidence isn't real high at this point.

Thanks,

Ian

Probably you have an error that shuts down the process, run the same project
using VS2008 to discover it.

Good catch. Thanks for teaching me an important Blend debugging technique...

Now, I don't really know what to do with this new found knowledge.
Apparently, the problem is in the fact that I put a gradient background on my
form. Looks fine in the designer, but not at runtime. Error is...

"'GradientStop' object cannot be added to 'LinearGradientBrush'. Handler has
not been registered with this event.
Parameter name: handler Error at object 'System.Windows.Media.GradientStop'
in markup file 'WpfBas;component/window1.xaml' Line 35 Position 62."

Here's the XAML...
