Code window resize
A feature you can turn on/off is automatic resizing of the code window. When you are editing your code, selecting the code window maximizes it at the expense of Solution Explorer, the Output pane, etc.
Edit code while it executes
You could do it with Visual Basic 6 back in the '90s and finally you can do it in VS2012. While the code is executing, you can pause it (breakpoint / debugging) and modify the code. Just as it did back in the '90s, the compiler will continue working with the code you just wrote.
Google It!
They just made everyone's life easier by providing a button called "Google It!" in case of any run-time error message box.
Automatically add semicolons.
Rumor has it that the compiler will also automatically add closing brackets and braces.
Advanced copy and pasting of code
The art of developing good software includes the skill of copying and pasting code found on the Internet. To make your life easier, VS2012 will apply some sense to the pasted code and rewire it for you. Simply write your stub method...Ask a question at StackOverflow.com or maybe try Goggling the code you need. Once you have it, simply copy the code and paste it into your stub method...then the magic begins. The compiler has recognized and wired up your connection string, replaced "textBox1.Text" with "term", and because you are returning a string from this method, it assumes that you want the first result from the table and so will suggest returning that for you.
Evil Code Monkey
After copying and pasting code, things can get pretty messy really quickly. IntelliSense now includes Evil Code Monkey™ which will point out your ugly code, shaming you into Googling the correct way to write it.
Language Style
VB, C# or F# - it's all just language styles!
When you are viewing code you can opt to have it translated from its original source into VB, C# or into some of the new styles.
Add Reference dialog
Finally they figured out what people meant when they asked for a proper "Add Reference" dialog. They now provide the ultimate mix of speed and flexibility.
The creation of high quality applications is also something which Microsoft is aiming for with the release of VS2012, with the inclusion of high quality testing and debugging tools that allow local debugging, as well as the ability to debug apps on the simulator and remotely on a connected device. Microsoft has undergone a lengthy process in an attempt to ensure that Visual Studio 2012 allows continuous value and quality to be delivered through the use of the software. With the inclusion of what they called Application Lifecycle Management, development teams of any size can be confident that required collaboration to deliver apps will be seamless and problem free.
