I'm having a go at adding a Mac project to my Forms solution for the first time, and I'm finding that the doco appears to be out of date. I've been following https://docs.microsoft.com/en-us/xamarin/xamarin-forms/platform/mac (and some others as well, but all say the same thing) and I'm finding that what is typed there isn't matching up with my intellisense. e.g. the doco says to add "using Xamarin.Forms.Platform.MacOS;" but the closest thing that intellisense comes up with is "using Xamarin.Forms.PlatformConfiguration.macOSSpecific;" - I presume these are the same thing (the latter is a newer version of the former)? There are other differences too where intellisense fails to find what they have typed which gives me no confidence at all with getting this working. Is there some updated doco on this somewhere? It appears to have changed somewhat since the initial release of Mac support (I can't find anything newer than last year on this topic).
