16. Windows Applications Applications designed for the desktop
Designed for a single platform
Use classes from System.Windows.Form namespace
Applications can include menus, pictures, drop-down controls, buttons, textboxes, and labels
Use drag-and-drop feature of Visual Studio

Create New Project
Select New Project on the Start page
OR use File → New Project option

Change the name of the class and the source code filename
Use the Solution Explorer Window to change the source code filename
Select View → Solution Explorer
