Visual Studio 2010 has been re-designed with features such as a reorganized layout with file menus and commands on a “shelf” at the top of the IDE. As you can clearly see fom the screenshot, Microsoft has now begun to use Windows Presentation Foundation (WPF) for the evolution of toolbars and menu bars.
Visual Studio 2010 will also feature a new UI with which developers will be able to enjoy additional real estate space because of multi-monitor support and can also simply drag source code windows to a secondary monitor. Rather cool I must say!!
