Docs: Exception: Cannot find resource named 'nameItemTemplate'. Resource names are case sensitive.

[tapiov]

Hello,

On last build & launch, I get the following exception:

System.Windows.Markup.XamlParseException: ''Provide value on 'System.Windows.StaticResourceExtension' threw an exception.' Line number '38' and line position '55'.'

Exception: Cannot find resource named 'nameItemTemplate'. Resource names are case sensitive.

nameItemTemplate is found in two places within solution

1)
ItemsSource="{Binding Source={StaticResource ExpenseDataSource}, XPath=Person}"
ItemTemplate="{StaticResource nameItemTemplate}">

2)

       <!-- Name item template -->
        <DataTemplate x:Key="nameItemTemplate">
            <Label Content="{Binding XPath=@Name}"/>
        </DataTemplate>

Both within ExpenseITHome.xaml

The exception points to ExpenseITHome.xaml.cs, line 25, which reads

   public ExpenseITHome()
    {
        InitializeComponent();  // This is line 25
    }

Commenting out InitializeComponent(); makes the application work. Is there a point in the tutorial where this Initialize line is changed/removed? Did I just miss it? Why does the error occur?

As a side note: I really don't like editing lines and lines of axml code, readability is poor, structuring is poor etc. I am hoping that I can build these in Designer (or in Blend) and the code the main operation to .cs.

Thanks,

Tapio Valli
