The System.Windows.Forms.Integration namespace contains classes that enable interoperation between the Windows Forms and WPF technologies. When you use System.Windows.Forms.Integration classes, you can host Windows Forms controls on WPF pages, and WPF elements in Windows Forms-based applications.

The two key classes that implement interoperation capabilities are WindowsFormsHost and ElementHost. Which class you use depends on your control implementation:

• Use the WindowsFormsHost class when you must use a Windows Forms control on a WPF page.

• Use the ElementHost class when you must use a WPF element in a Windows Forms-based application.
