After adding the code in listing 2-3 (the Page.xaml), and right-clicking on "Open in Expression Blend", Expression Blend opens the project, but I get an "Invalid XAML" error in the designer window. Looking at the details, each of the items on the page get this type of error:

UserControl is not supported in a Windows Presentation Foundation (WPF) project.
Canvas is not supported in a Windows Presentation Foundation (WPF) project.
...

Is this a problem with my development environment? I thought I had it set up as specified in the book.

Thanks,

Jeff

Hey Jeff,

Are you sure you are working in a Silverlight application enviroment and not WPF web application?
