The first thing you’ll notice with Visual Studio 2017 is the new install experience which lets you pick and choose which development tools you want installed. To help you get started working on your projects quickly, Visual Studio 2017 Preview version 15.5 has parallelized initialization to make your solutions load fast and get you to writing code as soon as possible. Other performance improvements include moving computation –like code analysis—out of the main Visual Studio process to keep your typing speed unimpeded.
