Microsoft has released Preview 4 of Visual Studio 15, the forthcoming update to its flagship integrated development environment (IDE). One of the biggest changes in the preview is an improved installation experience. "The highlight of this release is that nearly all of VS is running on the new setup engine, resulting in a smaller, faster and less impactful installation," blogged John Montgomery, Microsoft's director of program management for Visual Studio. "The smallest install is less than 500 MB on disk (compared to 6GB in the previous release of Visual Studio)."
Other changes include some improvements to the way the IDE handles C++ and enhancements for IntelliSense, Microsoft's technology that provides code completion and context-sensitive help.
