Can't attach VS 2017 to 2021.1 beta?

Hey, when I try to attach VS 2017 to 2021.1 beta, VS just shows me an empty window where I’m supposed to select the Unity version:

6948467--817283--upload_2021-3-18_13-1-26.png

This works fine with Unity 2018.4 that I have installed as well. Do I need a different Visual Studio Tools for Unity? (If yes, why weren’t they installed together with 2021.1?) - Or do I need a newer version of VS? Or what else could be the reason?

Probably get more help with 2021.1 beta issues in the 2021.1 beta forum

Ok it does work properly with VS 2019
