Applications written in the Smalltalk-inspired language will require only a simple recompile to run on both Mac and Windows 7 systems, he said. According to Ballmer, Visual Objective-C will also appear in Visual Studio 2010 SP1 for Windows. The centerpiece of Visual Studio for Mac OS X is Visual Objective-C, a native implementation of Apple’s preferred object-oriented programming language, which is used on both Mac OS X and the iPhone SDK. Standing in front of a giant poster of the new Visual Studio for Mac OS X, his voice hoarse with emotion, Ballmer screamed, “Now it’s time to give something back!” “Every day, our Windows 7 dev team is inspired by the great work being done by the visionaries in Cupertino.” “We never stopped loving the Mac,” he shouted, waving an iPhone. The company’s Excel spreadsheet software first appeared for the Mac in 1985, he bellowed, two full years before Microsoft released a Windows version. Speaking to a full crowd at the Meydenbauer Center, Ballmer reminded the audience that Microsoft is one of the oldest and most competitive ISVs for Apple’s Macintosh platform.
