Page 2.1.2 - 2.1.5
Page 2.1.2, Example 2.1-1 |
I created a WEBSITE for the Text1 example as the book recommends. I typed example 2.1-1 into the .xaml file;
<UserControl x:Class="Text1.Page"
xmlns="http://schemas.microsoft.com/cilent/2007"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Width="400" Height="300">
<Grid x:Name="LayoutRoot" Background="White">
<Canvas>
<TextBlock>Silverlight</TextBlock>
</Canvas>
</Grid>
</UserControl>
Running the website produces the following error;
ParserError- AG_E_PARSER_NAMESPACE_NOT_SUPPORTED
File: Scene.xaml, line 4 character 29
I generated the same .xaml in Expression Belend 2.5 beta and it used the following namespace; xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" instead of the following namespace used in the book;
xmlns="http://schemas.microsoft.com/cilent/2007".
This produces the following error;
ParserError- XamlReader.Load() does not support x:Class.
File: Scene.xaml, line 4 character 29
At this point I downloaded the source code for the book and found that it implemented the code for this example as a project rather than a website. Emulating the downloaded code, I recreated the example as a project and everything worked just fine.
I'm a profesional programmer but a Silverlight and WPF newbie so I don't really have much in the way of intuition as to what is happening here save to say the technology is probably changing quickly. I would recommend, however, that the source code download for the book be consistent with the examples in the book.

Note from the Author or Editor:
Correct; Microsoft changed the namespace for beta 2, unfortunately. Recent builds of the plugins complain here. Please refer to the first "Hello World" example right after the installation for the correct namespaces. |
