Recently I updated my Visual Studio to Visual Studio 2017 and I also updated my Unity to 5.6.
Right now, in Visual Studio the button for “Attach to Unity” is gone. Is there anyway to fix this problem?
Of course when you install your own version of VS it doesn’t have the preinstalled Unity Tools for Visual Studio installed which are bundled with the VS version that is shipped with Unity. The extension seems to be located at:
C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\Extensions\Microsoft\
there’s a folder called “Visual Studio Tools for Unity” which is a Visual Studio extension. You may be able to copy that folder in your newer VS version. However it’s not clear if this is the only “modification” that Unity has done to VS.
