You have access to all of the same namespaces that a native app does, and also access to all of the namespaces included in .net Framework Standard.

You can stay within .net Framework Standard and share that code between your Android/iOS/Windows Phone(lol) app, and reach into the native libraries when you need platform specific functionality.
