Opening scripts opens a new vs window every single time.

Hello community! I am new to Unity (semi-transferring from Unreal ;)) and trying to learn how to use this properly. I have installed Unity and VS2015 Community Edition (Lastest version to the posting date). The problem is that when I try to open a script from unity content browser, it opens in the vs on a new vs window instead of opening on a tab on a pre-existing vs window. For example, lets say I have someclass.cs, even if it’s the same script, if i try to double click to open, it just opens a new visual studio to open its file. This is really frustrating me out. Since I’m new, I have no idea if this is the norm that I have to get used to. I couldn’t find any answer on the web that had my kind of problem. The workaround that I have found is simply dragging the script from unity content but that’s really annoying. Can someone please help me out? Thanks!

for tl;dr :

  1. opening scripts opens up new visual studio every single time.
  2. just want opening scripts to open up in new tab in pre-existing visual studio.

Take a look at your preferences in VS itself for UnityVS. Check your options there.
