I'm trying to create a multiplatform library that supports iOS, Android, and UWP. The VS for Mac project template only supports iOS and Android. For VS for Windows, I've only found a confusing maze of outdated documentation. It seems I'm supposed to use the "Nugetizer 3000" extensions, but those require VS 2017 and I don't think I should have to install an old version of VS just to make a NuGet package. There doesn't seem to be a template for this at all on Windows, and that's the only environment where I can interact with UWP.
