The WPF Designer is the tool in Visual Studio that provides the WYSIWYG design surface for building WPF windows. In many ways, it behaves just like the designers we use for web forms and Windows forms. But it is in fact a brand-new tool, with some subtle differences over its IDE brethren.

The project template we want to select is WPF Application, and it is located in the Windows category on the New Project dialog box (see Figure 21.3).
