For window-based applications targeting the CLR, you use Windows Forms as the base for the GUI provided by the .NET Framework libraries. Us ing Windows Forms enables rapid GUI development because you assemble the GUI graphically from standard components and have the code generated completely automatically. You then just need to customize the code that has been generated to provide the functionality you require. For natively executing code, you have several ways to go. One possibility is to use
