EDIT : BUG Fixed in unity 2019.1.4f1 Hello devs, I have stumbled upon this issue while coding some new stuff i have never worked with before. I have gotten used to the API so i just didn't notice, but coding this new functionality (drag and drop stuff) i am clueless and i need these desc to find what i am looking for quickly without going to the docs every 5 mins. I went back to older projects to see if it worked in 2018.3.7 and yes there i have full desc. I cant find much info on this, and it seems not meny people are having this issue but some people are asking on the Unity Answer and not getting answer so i thought i would try my luck here, Here are also pics of the problem. It seamed the 2019 installation is messed up, so i reinstalled. same problem. VS 2019 works with unity 2018 and on other non unity related projects. i want to blame Unity Hub for this but i found some information from before the HUB so i am not sure where the problem can be. I did try the solution but it didn't work for me, and i am not sure how to reconnect the XML files which hold the function desc. Side Note -> check out this installation path ( Unity\Hub\Editor\2019.1.1f1\2019.1.3f1\Editor ) Is this Normal ??? i was going to delete my 2019.1.1f1 install since i updated , would this delete the new update? UnityHub can i choose where to install my stuff somehow ?
