If you want a hint of just how big Visual Studio has become, consider its new Quick Launch capability. The idea behind Quick Launch: There's some operation in the IDE you want to perform, but you can't quite remember in which submenu or toolbar selection or pop-up window the control for that operation is hiding. Wouldn't it be nice if you could search the IDE, in the same way you, say, search for a variable's definition in your project's source?
That's exactly what Quick Launch lets you do. Enter a search string, and the IDE groups the results of your search. You can see matches in the most recent controls you've used, the documents you've opened, or menus or options you've selected. Click on one of the choices and -- hopefully -- you'll be taken to the spot in the IDE you're looking for.
As I warned at the beginning, Visual Studio 2012 is a big product. There's a whole lot more I didn't touch on: testing features, project lifecycle management, version control features, Visual Studio's integration with other Microsoft products, and so on.
If you want to do Windows development -- particularly Windows 8 and RT development -- then Visual Studio is really the only game in town. This is simultaneously a blessing and a curse. On the one hand, Visual Studio 2012 does an admirable job as the platform for building applications for a dizzying variety of targets. On the other hand, if you don't like it, you're pretty much stuck with it. Nevertheless, countless successful applications, small and large, were born, raised, and graduated from the Visual Studio IDE. And countless more are still to come.
