<controlsPrimitives:DatePickerTextBox x:Name="TextBox" Margin="0,0,20,0" Height="22" Background="{TemplateBinding Background}" Selectionremoved="{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}"/> 

This sample buid successed but at runtime in InitializeComponent() method I got this Error =>

 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 

If I delete controls, CalenderItem or DatePickerTextBox the Error do not occur.

How can I solve this problem.
