• 创建控件项目
在我们刚刚使用的StartPage解决方案中，添加一个Visual C#项目imccBlog，项目模板选择WPF User Control Library。项目创建完成后，为项目添加下列dll的引用：
C:\Program Files\Microsoft Visual Studio 10.0\Common7\IDE\Microsoft.VisualStudio.Shell.UI.dll
通过添加此dll的引用，我们可以在XAML中执行Visual Studio的内部命令。
• 编辑UserControl1.xaml
编辑UserControl1.xaml的内容如下，以读取RSS并显示在开始页中：
<UserControl x:Class="imccBlog.UserControl1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:vs="clr-namespace:Microsoft.VisualStudio.PlatformUI;assembly=Microsoft.VisualStudio.Shell.UI">
<Grid>
<Grid.Resources>
<XmlDataProvider x:Key="imccBlog" XPath="rss/channel" Source="http://imcc.blogbus.com/index.rdf" />
</Grid.Resources>
<Border BorderBrush="Black" BorderThickness="1" CornerRadius="10" Padding="4" Margin="0,0,0,10" >
<ItemsControl DataContext="{StaticResource imccBlog}" ItemsSource="{Binding XPath=item}" BorderBrush="Transparent" Padding="6" >
<ItemsControl.ItemTemplate>
<DataTemplate>
<TextBlock Margin="0,0,0,6">
<Image Source="C:\Users\Public\Documents\CTPWalkthroughs\Visual Studio\Samples\Start Page\greendot.png" Height="10" Margin="0,0,5,0" />
<Hyperlink Foreground="White" Command="{x:Static vs:VSCommands.Browse}" CommandParameter="{Binding XPath=link}">
<TextBlock FontSize="12" Text="{Binding XPath=title}" /></Hyperlink></TextBlock>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</Border>
</Grid>
</UserControl>
