我正在开发一个基于 Silverlight 5 的应用程序。它的框架 4.5 是 MVVM 架构，由 Prism 实现。我也在使用 silverlight 5 工具包。

</StackPanel>
</ControlTemplate>
<controlsPrimitives:DatePickerTextBox x:Name="TextBox" Margin="0,0,20,0" Height="22" Background="{TemplateBinding Background}" SelectionBackground="{TemplateBinding SelectionBackground}" BorderThickness="1,1,0,1" Foreground="{TemplateBinding Foreground}" FontFamily="{TemplateBinding FontFamily}" FontSize="{TemplateBinding FontSize}" Padding="{TemplateBinding Padding}" HorizontalContentAlignment="{TemplateBinding HorizontalContentAlignment}" Style="{StaticResource System.Windows.Controls.Primitives.DatePickerTextBox}"/>
此示例构建成功，但在运行时在 InitializeComponent() 方法中我收到此错误 =>
The type 'controlsPrimitives:CalendarItem' was not found. Verify that you are not missing an assembly reference and that all referenced assemblies have been built
The type 'controlsPrimitives:DatePickerTextBox' was not found. Verify that you are not missing an assembly reference and that all referenced assemblies have been built
如果我删除控件、CalenderItem 或 DatePickerTextBox，则不会发生错误。
我怎么解决这个问题。
