I just upgraded to Unity 5.2 and I am currently using Visual Studio 2013 Professional edition. Our company is to large to be able to legally use 2015 community so upgrading is not currently an option. With the tight integration with Visual studio 2015 community it appears it has broken my ability to debug with VS 2013 Professional. Is there a setting that could possibly fix this? I have tried deleting the UnityVS tools stuff but VS 2013 still opens without the ability to attach to Unity. Any possible solutions?
