Hello, i have a visual studio code project in c#. This project is used in all my unity projects (i set them the .dll). This VSC project needs UnityEngine.dll, UnityEngine.UI.dll that i took from unity 2018. Now i want to updgrade my vsc project with unity 2019.2.2f1 but UnityEngine.UI.dll doesn't exist anymore, how can i do ? i tried to keep the old UnityEngine.UI.dll in my vsc project, which i could successfully generate the dll but when i insert my vsc dll in my unity project with unity 2019.2.2, i get an error which say that i can't use UnityEngine.UI in my vsc project. I have see about the asmdef but this is not a file i can include in my vsc project isn't it ? Thank you.
