Well I have a problem, and is that when I create a new project all packages are stored on Library/PackageCache but not in Packages folder (which contains only manifest.json file). The problem generated here is that when I try to attach the solution to Unity (using "Attach to Unity" button on Visual Studio), Visual Studio throws a lot of errors at building time saying for example that TextMeshPro files miss. I have read before that I have to delete this packages but no clue of how to do it (maybe erasing ""com.unity.textmeshpro": "1.3.0"," line from manifest.json, but maybe this could cause more problem, I don't know). But the more evident problem is causes when I try to install a local package (one made by me). Actually, I'm working on Zios Theme Editor, I created a package using ASMDEF files, and everything go wells except for one situation: when I try to install this from scrach. Is like the local package is located at the wrong placed. This doesn't occurs when I manually copy the entire folder into Packages folder and I compile for first time the project. So, I'm missing something or what?
