I have started using VS 2015. In the past, I have composed KT/HS-ATS and KO-ATC on VS 2008.
The new screen looks cool, and it indicates immediately if the code has inconsistencies. So far there is no issue in converting my existing files from 2008 to the current version. I felt a small confusion about the different behaviour of “Find All Reference” functionality on the right-click menu. The 2008 listed precisely the same variable but the 2015 lists other variables that are used in other classes within the same project. Maybe there are some better usages, or I have to improve.
