In other technologies such as Windows Forms and Web Forms, you can adorn a class with the [ToolboxItem(false)] attribute and it will not appear in the Visual Studio Toolbox.
In Windows Presentation Foundation (WPF) you use the [ToolboxBrowsable(false)] attribute instead. This attribute is found in the Microsoft.Windows.Design namespace in the Microsoft.Windows.Design.dll assembly.
