Have vstools for 2019 installed… but Unitiy no longer opens VS at the point of an error line etc, or even shows the errors in vs error console like before, and even the solution explorer in vs isn’t showing the project like it used to… pretty much just treating devenv like a notepad for each file opened… unlike before with vs2018 … really broken and I’m still unsure of why the Hub doesn’t have the vstools bit to download.
I also got problem.
I can’t select VS 2019 in Unity editor preferences.
yeah it used to be visual studio in the external script editor… now it’s just devenv.exe with no other option :S
I had to uninsatll VS and erase old data in APP data folder.
What I found that compiling scripts takes longer time than in old monodevelop.
My PC is not fast and gets anoying because Unity completely frezees when VS is compiling.
hmm? well I reinstalled vs2017 only took another 1.3gb to put back again, and now unity detects Visual Studio, and doesn’t need the devenv.exe shortcut… it all works like it did before… sad they couldn’t have gotten that all working properly for vs2019 and unity 2019.1 releases
UnityEditor 2019.1.0f2 detects fine Visual Studio 2019 (Enterprise) - I uninstalled VS 2017 before installing VS 2019 and Unity Editor (using the Hub)
well that’s strange, because I also uninstalled vs2017 before installing vs2019 (community), and then installed unity2019.1 and that detected nothing… even installed the vstools for unity in vs installer.

I can’t attach Unity to VS2019. Game dev tools are installed, too: No dice.
EDIT: GOT IT (Unity 2018.3)! I went to Edit >> Prefs >> External tools >> Default editing app, it was default to “devenv.exe” instead of “Visual Studio 2019”.
Swapped it, closed VS, went to Unity’s Assets >> Open C# Project (not sure if this part’s required) >> works!

I don’t get that option at all in Unity, despite vs2019 being installed.
Did you also install the “Tools for Unity” in teh same installer?
why I did yes
Yea same here. I can’t open VS 2019… and now VS2017 is crashing on me. 
for some reason unity just stopped opening my files in Visual Studio 2017. I can change the editor to VSCode and it works, but no dice when its set to 2017. just came out of the blue.
I had this same problem with 2019.2 and VS2019. Then I noticed in the release notes, “Editor: Added VSCode, Visual Studio, and Rider code editor integration as Packages.” My project had an old version of the Visual Studio Editor package. After upgrading it to the latest version, Visual Studio started working again with the Unity editor.
