I am planning to start a new web design project in July and take the opportunity to upgrade from Q2 2013 asp.net ajax toolset to Q2 2016 and move from VS 2012 to VS 2015 community edition at the same time. Production website will be running on iis 7.5. I assume this will be fine...?
However, if I have to use this development setup to maintain or extend an existing website with 2013 controls, what problems might I expect, and how should I avoid them!
Thanks for any insights on avoiding action that you can give me before I hit a pothole
