IMHO the full .NET is from today considered a legacy platform. I would compare the situation to WebForms / MVC - who does new projects with WebForms now?

As far as I remember the long term plan is to stack the remaining APIs from the full .NET on top of .NET Core.

So Microsoft would have: .NET Core - base for everything. .NET - Windows specific bits, Xamarin - mobile specific bits.
