From the experience of trying to convince people to upgrade from VB6 to .NET using a "big-bang" approach, Microsoft has acknowledged that few organizations are likely to accept this as a viable upgrade path. So Microsoft has provided bi-directional interoperability support between WPF and Windows Forms applications through what is colloquially called Crossbow. In essence this is really about providing a hosting element with a Windows Forms application so that a WPF control can be inserted. Let's show this with a bit of an example based on the work you have done so far.

From the Add New Item dialog (see Figure 35-17), select the User Control (WPF) item. This will add the XAML and xaml.vb files necessary to create a WPF user control. If you examine the XAML you will see that it is essentially the same as the original XAML for the window we started with at the beginning of the chapter except that the root XAML element is UserControl instead of Window.
