Lots of new features are bundled in this release of Visual Studio 15 preview !!! My favorite is how fast it can open a BIG solution and how seamless it is to switch from one branch to another without the constant reloading...good stuff!

Improvements in performance:

  • Shorter solution load time with lightweight project load (my favorite)
  • Faster startup with on-demand loading of extensions
  • Moving subsystems from the main VS process to separatel processes
  • Faster project load, coding, and debugging for C++
  • Improved speed of Git source control operations by using git.exe

Improvements in productivity:

  • Code Edition
  • Quick Fixes and Refactorings (close second)
  • Code Navigation
  • Debugging
