@Ian: If you could point me to the exact time in the video I could offer a better answer.  Off the top of my head / not looking at the video (1) I was following the instructions of the Hands On Labs Smiley and (2) why the author of the Lab chose not to use StringBuilder?  Speculation, but perhaps the amount of appending didn't warrant it, or they were just keeping everything obvious and simple.  You can feel free to use whatever method you prefer.  Good luck!

I'm very new to programming so wasn't sure if I was missing something obvious

In your download there are folders of the application for chapters 3-5, 9 and 24.  There is no CS_15 folder for the lesson in question ("Part 15: Implementing Type Converters").  I looked in the CS_24 folder hoping to find it there but ItemDetailPage.xaml has no reference to <FlipView.Template> and ListConverter.cs isn't there either.

I'm sure it's in the Lab download, I just didn't get around do downloading it (it seems large and was hoping to avoid getting it).

Anyway, thanks Bob for your great work.

http://social.msdn.microsoft.com/Forums/en-US/csharpgeneral/thread/d85dc60d-d8c9-4a98-a769-ce7819024196/

It means you've hit a bug in the code you typed in.  Since you didn't land on C# code, I'm going to guess it's a problem with your XAML code.  I'm guessing this is related to your other issue with the blue squiggly line under line 85 in your XAML.  Since it's dealing with the Type Converter AND this is not a compilation error -- but rather a runtime error, I'm guessing you didn't implement it correctly and when you call it from XAML it breaks.  Perhaps you're missing a accessibility modifier like Public?  If I were you I would CLOSELY comb through my code.  Worst case ... compare ( or even copy the code) from the Windows 8 Lab in a Box / Contoso Cookbook Hands on Lab and paste it into your project ... both the List Converter AND the XAML that calls it to see if it fixes the problem.

I've never hit the error you describe, so outside of helping you debug it, I don't exactly why you're getting it.
