Visual Studio project "needs migration".
Visual Studio don't open the unity project. Visual Studio Tools for Unity is installed but disabled. I can't enable it. Unity 2017.3.1f1 but same thing on 2018.1.
I started getting this after I updated Visual Studio to version 15.7.1. The unity extension for visual studio had stopped working.
Here is the solution that worked for me:
Open the Visual Studio Installer
Click Modifiy
Uncheck "Game development with Unity" and click modify.
Wait for it to uninstall
Re-open the Visual Studio Installer
Modify
Check "Game development with Unity" and click modify.
Wait for it to install
...
Make games
Just wanted to add to this, I just updated to 2019.3.1f1, same issue. I tried this solution without any luck, but uninstalling Visual Studio completely and then re-installing through the Unity Hub (Select Installation, Add $$anonymous$$odules, VS 2019) did the trick!
Thanks. I solved this problem not long after writing this post by installing older versions of Visual Studio for Unity.
